967,828 SHARES
 
METRIKA SYSTEMS CORPORATION
 
COMMON STOCK
($.01 PAR VALUE)
 
     This Prospectus relates to the resale of 967,828 shares (the "Shares") of
Common Stock, par value $.01 per share (the "Common Stock"), of Metrika Systems
Corporation (the "Company") by certain shareholders of the Company (the "Selling
Shareholders"). The Shares may be offered from time to time in transactions on
the American Stock Exchange, in negotiated transactions, through the writing of
options on the Shares, or a combination of such methods of sale, at fixed prices
that may be changed, at market prices prevailing at the time of sale, at prices
related to such prevailing market prices or at negotiated prices. Such
transactions may be effected by the sale of the Shares to or through
broker-dealers, and such broker-dealers may receive compensation in the form of
discounts, concessions or commissions from the sellers and/or the purchasers of
the Shares for whom such broker-dealers may act as agent or to whom they sell as
principal, or both (which compensation to a particular broker-dealer might be in
excess of customary commissions). The Selling Shareholders and any broker-dealer
who acts in connection with the sale of Shares hereunder may be deemed to be
"underwriters" as that term is defined in the Securities Act of 1933, as amended
(the "Securities Act"), and any commission received by them and profit on any
resale of the Shares as principal might be deemed to be underwriting discounts
and commissions under the Securities Act. The Shares were originally sold by the
Company in private placements pursuant to certain Stock Purchase Agreements with
the Company dated December 16, 1996 and December 27, 1996 (the "Purchase
Agreements"). See "Selling Shareholders."
 
SEE "RISK FACTORS" COMMENCING ON PAGE 4 FOR A DISCUSSION OF CERTAIN FACTORS THAT

HEREBY.
 
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.
 
     None of the proceeds from the sale of the Shares by the Selling
Shareholders will be received by the Company. The Company has agreed to bear all
expenses (other than underwriting discounts and selling commissions, and fees
and expenses of counsel or other advisors to the Selling Shareholders) in
connection with the registration and sale of the Shares being registered hereby.
The Company has agreed to indemnify the Selling Shareholders against certain
liabilities, including liabilities under the Securities Act as underwriter or
otherwise.

                                  THE COMPANY
 
     Metrika Systems Corporation ("Metrika Systems" or the "Company") develops,
manufactures and markets on-line industrial process optimization systems that
employ proprietary ultra-high speed advanced scientific measurement technologies
for applications in raw materials analysis and finished materials quality
control. The Company operated as two divisions of Thermo Instrument Systems Inc.
("Thermo Instrument") until its incorporation as a Delaware corporation in
November 1996. In connection with the Company's incorporation, Thermo Instrument
transferred to the Company the assets, liabilities and business of its
Gamma-Metrics subsidiary and Radiometrie division ("Radiometrie") in exchange
for 5,000,000 shares of the Company's common stock. Unless the context otherwise
requires, references in this Prospectus to the Company or Metrika Systems refer
to Metrika Systems Corporation and its subsidiaries and the predecessor business
which constitute the Company. The Company's on-line raw materials analyzer
business is conducted by its Gamma-Metrics subsidiary based in San Diego,
California, and its on-line finished materials quality control business is
conducted by its Radiometrie division with operations in Erlangen, Germany and
Gloucester, England. As of October 20, 1997, Thermo Instrument beneficially
owned 60.5% of the outstanding Common Stock. The Company's principal executive
offices are located at 5788 Pacific Center Boulevard, San Diego, California
92121, and its telephone number is (619) 450-9649.

                                  RISK FACTORS
 
     In addition to the other information in this Prospectus, investors should
carefully consider the following risk factors when evaluating an investment in
the shares of Common Stock offered hereby. This Prospectus contains
forward-looking statements that involve risks and uncertainties, such as
statements of the Company's plans, objectives, expectations and intentions. The
cautionary statements made in this Prospectus should be read as being applicable
to all forward-looking statements wherever they appear in this Prospectus. The
Company's actual results could differ materially from those discussed herein.
Factors that could cause or contribute to such differences include those
discussed below, as well as those discussed elsewhere in this Prospectus.
 
     Dependence on Capital Spending Policies.  The Company's customers include
coal burning utilities, coal mines, cement manufacturers, and manufacturers of
web-type materials such as steel, plastic and rubber. The capital spending
policies of these companies can have a significant effect on the demand for the
Company's products. Such policies are based on a wide variety of factors,
including the resources available to make such purchases, the spending
priorities among various types of process control equipment or techniques and
policies regarding capital expenditures during recessions. Any decrease in
capital spending by these customers could have a material adverse effect on the
Company's business and results of operations. Further, the Company's growth is
dependent in part on construction and upgrade of manufacturing plants in the
basic materials industries. A recession in one or more markets could cause a
slowdown or reduction in capital spending and in new plant construction. Growth
of the Company's on-line finished materials quality control business has
recently been adversely affected by a recession in Germany.
 
     Uncertainty of Market Acceptance of New Products.  Certain of the Company's
products represent alternatives to traditional instruments and methods. As a
result, such products may be slow to achieve, or may not achieve, market
acceptance, as customers may seek further validation of the efficiency and
efficacy of the Company's technology. This is particularly true where the
purchase of the product requires a significant capital commitment. Further,
because on-line process control systems are incorporated into a customer's
production line, a decision to invest in these systems involves significant
operating risks if the system fails or shuts down. The Company intends to expand
its product base by adapting its proprietary technologies for new applications
in broader industry segments including the pharmaceutical, agrochemical and
industrial chemical industries. The Company believes that, to a significant
extent, its growth prospects depend on the continuing acceptance by a broader
group of customers and by broader industry segments of its new products and
technologies. There can be no assurance that the Company will be successful in
adapting its proprietary technologies for new applications, in obtaining these
acceptances or, if obtained, that such acceptances will be sustained. The
failure of the Company to obtain and sustain such acceptances could have a
material adverse effect on the Company's business and results of operations.
 
     Technological Change and New Products.  The market for on-line process
optimization systems is characterized by changing technology, evolving industry
standards and new product introductions. The Company's future success will
depend in part upon its ability to enhance its existing products and to develop
and introduce new products and technologies to meet changing customer
requirements and to successfully serve broader industry segments. The Company is
currently devoting significant resources toward the enhancement of its existing
products and the development of new products and technologies. There can be no
assurance that the Company will successfully complete the enhancement and
development of these products in a timely fashion or that the Company's current
or future products will satisfy the needs of the on-line process optimization
systems markets. Any failure to complete the enhancement and development of
these products or the failure of the Company's current or future products to
satisfy market needs could have a material adverse effect on the Company's
business and results of operation.
 
     Risks Associated with Acquisition Strategy.  The Company's strategy
includes the acquisition of businesses and technologies that complement or
augment the Company's existing product lines. Promising acquisitions are
difficult to identify and complete for a number of reasons, including competi-
 
                                        4
<PAGE>   5
 
tion among prospective buyers, the need for regulatory approvals, including
antitrust approvals, and the high valuations of businesses resulting from
historically high stock prices in many countries. There can be no assurance that
the Company will be able to complete future acquisitions or that the Company
will be able to successfully integrate any acquired business. In order to
finance such acquisitions, it may be necessary for the Company to raise
additional funds through public or private financings. Any equity or debt
financing, if available at all, may be on terms which are not favorable to the
Company and, in the case of equity financing, may result in dilution to the
Company's stockholders.
 
     International Operations and International Sales.  In 1994, 1995, 1996 and
the six months ended June 28, 1997, sales originating outside the U.S. accounted
for 59%, 58%, 56% and 48%, respectively, of the Company's total revenues. In
addition, in 1994, 1995, 1996 and the six months ended June 28, 1997, U.S.
export sales accounted for 24%, 23%, 26% and 36%, respectively, of the Company's
total revenues. The Company anticipates that sales outside the U.S. and U.S.
export sales will continue to account for a significant percentage of the
Company's total revenues. The Company intends to continue to expand its presence
in international markets. International revenues are subject to a number of
risks, including the following: agreements may be difficult to enforce and
receivables difficult to collect through a foreign country's legal system;
foreign customers may have longer payment cycles; foreign countries may impose
additional withholding taxes or otherwise tax the Company's foreign income,
impose tariffs or adopt other restrictions on foreign trade; U.S. export
licenses may be difficult to obtain; the protection of intellectual property in
foreign countries may be more difficult to enforce; and fluctuations in exchange
rates may affect product demand and may adversely affect the profitability in
U.S. dollars of products and services provided by the Company in foreign markets
where payment for the Company's products and services is made in the local
currency. In 1996, effects of currency translation, due to a stronger U.S.
dollar, decreased revenues by $0.9 million. Further, a significant portion of
the Company's business is conducted in foreign countries, particularly Germany.
Foreign operations are also subject to certain risks such as general economic
conditions in the countries in which the Company operates, unexpected changes in
regulatory requirements, compliance with a variety of foreign laws and
regulations and overlap of different tax structures. Tax rates in certain
foreign countries exceed that of the United States and foreign earnings may be
subject to withholding requirements or the imposition of tariffs, exchange
controls or other restrictions. There can be no assurance that any of these
factors will not have a material adverse effect on the Company's business and
results of operations.
 
     Competition.  The Company encounters intense competition in the sale of its
on-line finished materials quality control products. The Company believes that
the principal competitive factors affecting the market for on-line process
optimization systems include quality and reliability, accuracy, price, customer
service and support, ease of use, distribution channels, technical features and
compatibility with customers' manufacturing processes. Certain of the Company's
competitors have greater resources, manufacturing and marketing capabilities,
technical staff and production facilities than those of the Company. As a
result, they may be able to adapt more quickly to new or emerging technologies
and changes in customer requirements, or to devote greater resources to the
promotion and sale of their products than can the Company. Further, competition
with respect to all of the Company's products could increase if new companies
enter the market or if existing competitors expand their product lines. There
can be no assurance that competitors of the Company will not develop
technological innovations that will render products of the Company obsolete.
 
     Proprietary Rights.  Proprietary rights relating to the Company's products
will be protected from unauthorized use by third parties only to the extent that
they are covered by valid and enforceable patents or are maintained in
confidence as trade secrets. The Company has 12 U.S. patents which have
expiration dates ranging from 1998 through 2014. The Company also owns
corresponding foreign patents in a number of jurisdictions throughout the world.
There can be no assurance that any patents now or hereafter owned by the Company
will afford protection against competitors. Proceedings initiated by the Company
to protect its proprietary rights could result in substantial costs to the
Company. Recently, the Company's Gamma-Metrics subsidiary initiated a lawsuit in
the Federal District Court in San Diego, California, alleging among other
things, patent infringement against Scantech Limited and its subsidiary Mineral
Control Instrumentation Ltd. There can be no assurance that competitors of the
 
                                        5
<PAGE>   6
 
Company, some of whom have substantially greater resources than those of the
Company, will not initiate litigation to challenge the validity of the Company's
patents, or that they will not use their resources to design comparable products
that do not infringe the Company's patents. The Company could incur substantial
costs and diversion of management resources with respect to the defense of any
such claims, which could have a material adverse effect on the Company's
business, financial condition, and results of operation. Furthermore, parties
making such claims could secure a judgment awarding substantial damages, as well
as injunctive or other equitable relief, which could effectively block the
Company's ability to make, use, sell, distribute or market its products and
services in the U.S. and abroad. There may also be pending or issued patents
held by parties not affiliated with the Company that relate to the Company's
products or technologies. In the event that a claim relating to proprietary
technology or information is asserted against the Company, the Company may need
to acquire licenses to, or contest the validity of, any such competitor's
proprietary technology. It is likely that significant funds would be required to
contest the validity of any such competitor's proprietary technology. There can
be no assurance that any license required under any such competitor's
proprietary technology would be made available on acceptable terms or that the
Company would prevail in any such contest. There can be no assurance that the
steps taken by the Company to protect its proprietary rights will be adequate to
prevent misappropriation of its technology or independent development by others
of similar technology. In addition, the laws of some jurisdictions do not
protect the Company's proprietary rights to the same extent as the laws of the
U.S. There can be no assurance that these protections will be adequate.
 
     Dependence on Sole-source Suppliers.  Various components of the Company's
products are supplied by sole-source vendors. The Company has not experienced
significant difficulty in obtaining adequate supplies from these vendors, and
has identified alternate suppliers. However, there can be no assurance that the
unanticipated loss of a single vendor would not result in delays in shipment or
in the introduction of new products. Any such delays could have a material
adverse effect on the Company's business or results of operations.
 
     Government Regulations and Approvals.  The market for certain of the
Company's products, both in the U.S. and abroad, is subject to or influenced by
various domestic and foreign clean air and consumer protection laws. The Company
designs, develops and markets its products, in part, to meet customer needs
created by existing and anticipated regulations, and any changes in these
regulations may adversely affect consumer demand for the Company's products.
 
     Potential Fluctuations in Quarterly Performance.  Many of the Company's
products are large systems that may require significant capital expenditures.
Consequently, the timing of sales of these systems could affect the Company's
quarterly earnings. Further, the Company's quarterly operating results may also
vary significantly depending on a number of other factors, including the size,
timing and shipment of individual orders, changes in pricing by the Company or
its competitors, discount levels, seasonality of revenue, foreign currency
exchange rates, the mix of products sold, the timing of the announcement,
introduction and delivery of new product enhancements by the Company and its
competitors and general economic conditions. Generally, the Company recognizes
product revenues upon shipment of its products. Revenues on substantially all
contracts are recognized using the percentage-of-completion method. Typically,
the Company experiences higher revenues in the second half of each year due to
seasonality experienced by its on-line finished materials quality control
business primarily because customers tend to place their orders earlier in the
year so that they can have the systems installed either during the holiday
season in the third quarter or between Christmas and the New Year. Because
certain operating expenses of the Company are based on anticipated capacity
levels and a high percentage of the Company's expenses are fixed for the short
term, a small variation in the timing of recognition of revenue can cause
significant variations in operating results from quarter to quarter. There can
be no assurance that any of these factors will not have a material adverse
effect on the Company's business or results of operation.
 
     Dependence on Key Personnel.  The Company's success depends to a
significant extent upon a number of key employees, including members of senior
management. The loss of the services of one or more of these key employees could
have a material adverse effect on the Company. The Company has not obtained and
does not intend to obtain key-man life insurance policies for any key employee.
The
 
                                        6
<PAGE>   7
 
Company believes that its future success will depend in part on its ability to
attract, motivate and retain highly skilled technical, managerial and marketing
personnel. Competition for such personnel is intense and there can be no
assurance that the Company will be successful in attracting, motivating and
retaining key personnel. The failure to hire and retain such personnel could
materially adversely affect the Company's business and results of operations.
 
     Shares Eligible for Sale After this Offering.  The 5,000,000 shares of
Common Stock owned by Thermo Instrument will become eligible for sale under Rule
144 promulgated under the Securities Act commencing in November 1997. In
addition, subject to certain limitations described below under "Shares Eligible
for Future Sales," as long as Thermo Instrument is able to elect a majority of
the Company's Board of Directors, it will have the ability to cause the Company
at any time to register for resale all or a portion of the Common Stock owned by
Thermo Instrument. Additional shares of Common Stock issuable upon exercise of
options granted under the Company's stock-based compensation plans will become
available for future sale in the public market at prescribed times. Sales of a
significant number of shares of Common Stock in the public market following this
offering could adversely affect the market price of the Common Stock. See
"Relationship with Thermo Electron and Thermo Instrument," "Shares Eligible for
Future Sale."
 
     Potential Conflict of Interest.  For financial reporting purposes the
Company's financial results are included in the consolidated financial
statements of Thermo Instrument and Thermo Electron. The members of the Board of
Directors of the Company who are also affiliated with Thermo Electron or Thermo
Instrument will consider both the short-term and the long-term impact of
operating decisions on the Company as well as the impact of such decisions on
the consolidated financial results of Thermo Instrument and Thermo Electron. The
interest of Thermo Electron and Thermo Instrument on the one hand and the
Company on the other hand may differ. The Company is an indirect subsidiary of
Thermo Electron and is a party to various agreements with Thermo Electron. These
agreements may limit the Company's operating flexibility. See "Relationship with
Thermo Electron and Thermo Instrument."
 
     Lack of Voting Control.  The Company's shareholders do not have the right
to cumulate votes for the election of directors. Thermo Instrument beneficially
owns approximately 60.5% of the voting stock of the Company. Accordingly, Thermo

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
     The Company develops, manufactures and markets on-line industrial process
optimization systems that employ proprietary ultra-high speed advanced
scientific measurement technologies for applications in raw materials analysis
and finished quality control. The Company is a pioneer in the development of
process optimization systems that provide real-time, non-destructive analysis of
the composition of raw materials in basic materials production processes,
including coal, cement and minerals. The Company also manufactures advanced
systems which are used to measure and control parameters such as material
thickness, coating thickness and coating weight in web-type materials, such as
metal strip, rubber and plastic foils. Customers use these systems to improve
product quality and consistency, lower material costs, reduce energy consumption
and minimize waste.
 
     The Company intends to supplement its internal growth with strategic
acquisitions of complementary businesses. There can be no assurance that such
businesses will be available at prices attractive to the Company. On December
31, 1996, the Company acquired the assets, subject to certain liabilities, of
the Autometrics division of Svedala Industries Inc. ("Autometrics"), a
manufacturer and marketer of on-line analysis instruments for the minerals
processing industry.
 
     A significant portion of the Company's sales are for large systems, the
timing of which can lead to variability in the Company's quarterly revenues and
income. In addition, in 1996 approximately 56% of the Company's revenues
originated outside the U.S. and approximately 26% of the Company's revenues were
exports from the U.S. Revenues originating outside the U.S. represent revenues
of the Company's on-line finished materials quality control business. The
operations of the on-line finished materials quality control business are
located in Germany, the United Kingdom and France, which principally sell in
their local currencies. Exports from the Company's U.S. operation are
denominated in U.S. dollars. The Company generally seeks to charge its customers
in the same currency as its operating costs. However, the Company's financial
performance and competitive position can be affected by currency exchange rate
fluctuations. Since the operations of the on-line finished materials quality
control business are conducted in Europe, principally Germany, the Company's
operating results could be adversely affected by capital spending and economic
conditions in Europe. The Company's operating results have been adversely
affected by a recession in Germany. The Company's strategy is to expand its
on-line finished materials quality control business in the U.S. and Asian
markets, which in turn may reduce the Company's exposure to European market
conditions.

</TABLE>
 
     Revenues increased from $11.6 million in the first quarter of 1996 to $14.3
million in the fourth quarter of 1996, principally due to sales growth at the
on-line raw materials analyzer business, resulting from increased sales in
international markets. Revenues decreased to $12.6 million in the first quarter
of 1997 from $14.3 million the fourth quarter of 1996, principally due to a $2.1
million decrease in sales at the on-line finished materials quality control
business, resulting primarily from a decrease in demand at the German operations
of this business. Improvement in the gross profit margin from 41% in the first
quarter of 1996 to 43% in the second quarter of 1996 reflects improvement at the
on-line finished materials quality control business due to higher costs incurred
in the first quarter of 1996 related to the introduction of new products, offset
in part by a decrease in gross profit margin at the on-line raw materials
analyzer business primarily due to shipments of older, lower-margin products.
The increase in gross profit margin from 46% in the third quarter of 1996 to 50%
in the fourth quarter of 1996 reflects margin improvement at the on-line raw
materials analyzer business principally due to manufacturing efficiencies as a
result of an increase in volume, and margin improvement at the on-line finished
materials quality control business primarily due to a reduction in manufacturing
costs relating to new products. The decrease in the gross profit margin from the
fourth quarter of 1996 to the first quarter of 1997 was primarily due to a
decrease at the on-line finished materials quality control business, resulting
primarily from a decrease in volume. Improvement in the gross profit margin from
44% in the first quarter of 1997 to 46% in the second quarter of 1997 reflects
improvement at the on-line finished materials quality control business primarily
due to an increase in volume.
 
RESULTS OF OPERATIONS
 
  Six Months Ended June 28, 1997 Compared With Six Months Ended June 29, 1996
 
     Revenues increased 11% to $26.7 million in the first six months of 1997
from $24.2 million in the first six months of 1996, reflecting an increase of
$3.7 million at the on-line raw materials analyzer business, primarily due to
increased sales in international markets and the inclusion of $1.1 million in
revenues from
 
                                       13
<PAGE>   14
 
Autometrics, acquired December 31, 1996. These increases were offset in part by
a decrease in revenues at the on-line finished materials quality control
business due to a decrease in demand in Germany, offset in part by an increase
in sales in the U.S. and Asian markets. The unfavorable effects of currency
translation due to a stronger U.S. dollar decreased revenues by $0.5 million.
 
     The gross profit margin increased to 45% in the first six months of 1997
from 42% in the first six months of 1996. The gross profit margin at the on-line
raw materials analyzer business was unchanged at 48% in 1997 and 1996. An
increase in the gross profit margin due to the inclusion in 1996 of lower-margin
revenues from a large order, was offset by the inclusion in 1997 of lower-margin
revenues at Autometrics. The gross profit margin at the on-line finished
materials quality control business improved to 42% in 1997 from 38% in 1996 due
to higher costs incurred in the 1996 period relating to the introduction of new
products, and an increase in higher-margin sales in 1997 resulting from the
introduction of such new products.
 
     Selling, general and administrative expenses as a percentage of revenues
decreased to 25% in the first six months of 1997 from 26% in the first six
months of 1996, principally due to an increase in revenues. Research and
development expenses increased to $2.1 million in the first six months of 1997
from $1.4 million in the first six months of 1996, primarily due to an increase
in product development expenses at the on-line raw materials analyzer business.
 
     Interest income increased by $0.5 million in the first six months of 1997
primarily due to interest earned on the invested net proceeds from the Company's
December 1996 private placement. Interest expense increased to $0.4 million in
1997 from $0.3 million in 1996, principally due to an increase in short-term
borrowings at foreign divisions, as well as an increase in applicable interest
rates.
 
     The effective tax rate was 40% in the first six months of 1997 and 1996.
The effective tax rate exceeded the statutory federal income tax rate primarily
due to the impact of state income taxes, nondeductible amortization of cost in
excess of net assets of acquired companies and foreign tax rate and tax law
differences.
 
  1996 Compared With 1995
 
     Revenues increased 13% to $52.0 million in 1996 from $46.0 million in 1995,
reflecting sales growth at both the on-line raw materials analyzer and finished
materials quality control businesses. Revenues increased $3.4 million at the
on-line raw materials analyzer business primarily due to growing acceptance of
its product line in international markets, and $3.5 million at the on-line
finished materials quality control business largely due to the introduction of
its quality control product line in Asia. Revenues decreased $0.9 million due to
the unfavorable effect of currency translation due to the strengthening of the
U.S. dollar.
 
     The gross profit margin increased to 45% in 1996 from 44% in 1995. The
gross profit margin at the on-line raw materials analyzer business improved to
51% in 1996 from 44% in 1995 primarily due to product redesign and increased
sales of products which have lower manufacturing costs. The improvement was
offset in part by a decrease in the gross profit margin at the on-line finished
materials quality control business to 41% in 1996 from 44% in 1995, resulting
principally from additional costs associated with the continued introduction of
new products in the German operations of this business.
 
     Selling, general and administrative expenses as a percentage of revenues
increased to 26% in 1996 from 25% in 1995, primarily due to increased marketing
efforts in international markets resulting in an increase in staffing and higher
travel expenses at the Company's on-line finished materials quality control
operations in Germany. Research and development expenses increased to $3.0
million in 1996 from $2.6 million in 1995, principally due to an increase in
product development expenses at the on-line finished materials quality control
business in Germany.
 
     Interest expense decreased to $0.8 million in 1996 from $1.1 million in
1995 due to a decrease in short-term borrowings at the on-line finished
materials quality control business, as well as a decline in interest rates.
Interest income increased $0.1 million in 1996 primarily due to higher average
invested
 
                                       14
<PAGE>   15
 
balances of the Company's foreign operations, as well as interest earned on the
invested net proceeds from the Company's December 1996 private placement.
 
     The effective tax rate was 40% in 1996 and 42% in 1995. These rates exceed
the statutory federal income tax rate primarily due to the impact of state
income taxes, nondeductible amortization of costs in excess of net assets of
acquired companies and foreign tax rate and tax law differences. The effective
tax rate decreased in 1996 primarily due to proportionately less income before
provision for income taxes from Germany, which is taxed at a higher rate.
 
  1995 Compared With 1994
 
     Revenues increased 19% to $46.0 million in 1995 from $38.6 million in 1994,
primarily due to a $3.5 million increase in sales at the on-line raw materials
analyzer business resulting from the introduction of the cross-belt analyzer
product line, as well as a $1.8 million increase in sales at the on-line
finished materials quality control business. Revenues increased $2.1 million due
to the favorable effects of currency translation due to the weakening of the
U.S. dollar.
 
     The gross profit margin increased to 44% in 1995 from 43% in 1994,
principally due to an improvement in the gross profit margin at the on-line raw
materials analyzer business to 44% in 1995 from 40% in 1994 resulting from
product redesign and an increase in sales of products which have lower
manufacturing costs. The gross profit margin at the on-line finished materials
quality control business was unchanged at 44% in 1995 and 1994. Improvement in
the gross profit margin at the Company's operations in the United Kingdom and
France was offset by a decrease in gross profit margin at the German operations
resulting principally from additional costs associated with the introduction of
new products.
 
     Selling, general and administrative expenses as a percentage of revenues
decreased to 25% in 1995 from 27% in 1994 largely due to an increase in
revenues. Research and development expenses increased to $2.6 million in 1995
from $2.3 million in 1994, primarily due to an increase in product development
expenses at the German division of the on-line finished materials quality
control business.
 
     Interest expense increased to $1.1 million in 1995 from $0.7 million in
1994, primarily due to an increase in short-term borrowings at the on-line
finished materials quality control business.
 
     The effective tax rate was 42% in 1995 and 46% in 1994. These rates exceed
the statutory federal income tax rate primarily due to the impact of state
income taxes, nondeductible amortization of costs in excess of net assets of
acquired companies and foreign tax rate and tax law differences. The effective
tax rate decreased in 1995 primarily due to proportionately less income before
provision for income taxes from Germany, which is taxed at a higher rate, and
increased benefits from a foreign sales corporation.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Consolidated working capital was $44.5 million at June 28, 1997, compared
with $8.7 million at December 28, 1996. Included in working capital are cash and
cash equivalents of $51.8 million at June 28, 1997, compared with $20.2 million
at December 28, 1996. Additionally, included in working capital are short-term
borrowings and advances from parent company and affiliated companies of $15.5
million at June 28, 1997 and $18.9 million at December 28, 1996 (see Notes 5 and
6 to Consolidated Financial Statements).
 
     During the six months ended June 28, 1997, $2.5 million of cash was
provided by operating activities. Cash provided by the Company's operating
results was reduced primarily by a $3.4 million increase in inventories and
unbilled contract costs and fees, which was offset in part by a $2.7 million
increase in other current liabilities. Inventories increased primarily due to a
build-up of inventory in anticipation of shipments at the on-line finished
materials quality control business. The increase in unbilled contract costs and
fees occurred principally at the on-line finished materials quality control
business and resulted primarily from the timing of billings on
percentage-of-completion contracts.
 
                                       15
<PAGE>   16
 
     During the six months ended June 28, 1997, the Company expended $1.6
million of cash for investing activities. On December 31, 1996, the Company
acquired the assets, subject to certain liabilities, of Autometrics for $1.3
million in cash (see Note 9 to Consolidated Financial Statements). The Company
expended $295,000 for the purchase of property, plant and equipment during the
six months ended June 28, 1997.
 
     The Company's financing activities provided $30.0 million of cash in the
six months ended June 28, 1997. In June 1997, the Company sold 2,300,000 shares
of its Common Stock in an initial public offering for net proceeds of $32.5
million (See Note 9 to Consolidated Financial Statements). During the six months
ended June 28, 1997, the Company increased its foreign short-term borrowings by
$3.7 million and repaid $0.2 million of its long-term obligation. A decrease in
"Due to parent company and affiliated companies" used $6.0 million in cash
during the six months ended June 28, 1997 (see Note 5 to Consolidated Financial
Statements).
 
     During 1996, $7.8 million was provided by operating activities. Cash
provided by the Company's operating results was improved primarily by a $3.6
million decrease in unbilled contract costs and fees, offset in part by a $2.7
million decrease in billings in excess of contract costs and fees, which
resulted principally from the completion of two contracts.
 
     The Company expended $0.7 million on purchases of property, plant and
equipment during 1996.
 
     The Company's financing activities provided $11.1 million of cash in 1996.
In December 1996, the Company issued 967,833 shares of its common stock in a
private placement for net proceeds of $13.5 million (see Note 3 to Consolidated
Financial Statements). During 1996, the Company reduced its short-term
borrowings by $1.9 million, repaid $0.8 million of its long-term obligation and,
prior to its capitalization, transferred $2.4 million in cash to Thermo
Instrument. An increase in due to parent company and affiliated companies
provided $2.7 million in cash during 1996, primarily as a result of a $2.8
million borrowing from a wholly owned subsidiary of Thermo Instrument, which was
repaid in January 1997.
 
     The Company plans to make capital expenditures for property, plant and
equipment of approximately $0.4 million in the remainder of 1997. Although the
Company expects positive cash flow from its existing operations, the Company may
require significant amounts of cash for the acquisition of complementary
businesses. The Company expects that it will finance any such acquisitions
through a combination of internal funds, additional debt or equity financing
from the capital markets or short-term borrowings from Thermo Instrument or
Thermo Electron, although it has no agreement with these companies to ensure
that funds will be available on acceptable terms, or at all. The Company
believes that its existing resources are sufficient to meet the capital
requirements of its existing businesses for the foreseeable future.

                                    BUSINESS
 
     The Company develops, manufactures and markets on-line industrial process
optimization systems that employ proprietary ultra-high speed advanced
scientific measurement technologies for applications in raw materials analysis
and finished materials quality control. The Company is a pioneer in the
development of process optimization systems that provide real-time,
non-destructive analysis of the composition of raw materials in basic materials
production processes, including coal, cement and minerals. The Company also
manufactures advanced systems which are used to measure and control parameters
such as material thickness, coating thickness and coating weight in web-type
materials, such as metal strip, rubber and plastic foils. Customers use these
systems to improve product quality and consistency, lower material costs, reduce
energy consumption and minimize waste.
 
     Global competition is driving participants in the basic materials
industries to increase quality and reduce production costs. The optimization of
industrial production processes requires the collection and analysis of data for
both the composition of the materials used in the process as well as for
measuring the variance of the output from composition targets. Manufacturers
traditionally have used off-line sampling techniques and laboratory instruments
to obtain this data. The delays associated with these techniques do not permit
real-time adjustments to the manufacturing process. In order to provide
real-time process and quality control, measurement systems must be integrated
into the customer's production line and must rapidly measure, on a continuous
basis, the stream of the materials used or product produced, rather than a
sample. The systems must also generate precise and reliable measurements of the
materials using non-invasive and non-destructive measuring techniques. Finally,
the systems must rapidly analyze the measurement data and, using this data,
adjust automatically the manufacturing process in real-time, and often under
harsh industrial conditions.
 
     The Company's systems make real-time, on-line, non-invasive,
non-destructive, precise measurements of materials using advanced scientific
measurement techniques, including gamma spectroscopy, beta particle detection,
laser spectroscopy, x-ray fluorescence and ultrasound. The Company's systems
incorporate proprietary intelligent sensors that have been developed for
specific production processes along with ultra-high speed signal processing
electronics capable of processing, in some cases, up to one million electronic
impulses per second resulting from the detection of excited particles such as
photons. These systems can be combined with the Company's proprietary real-time
software to form integrated process optimization systems designed to fit the
customer's specific application. The Company has developed a reputation for
rugged and reliable sensor technology capable of operating in hostile industrial
environments. The Company's products can generate significant savings to the
customer as a result of reduced manufacturing costs, reduced material waste,
decreased energy costs and in some cases, savings in capital investment. In many
cases a customer can recoup its investment in one of the Company's systems
within six to eighteen months.
 
     The advent of rugged high-speed analytical measurement instrumentation has
only recently allowed for the development of on-line industrial process
optimization. The markets for the Company's systems, therefore, consist
primarily of the existing industrial facility base which may be retrofitted or
upgraded to incorporate on-line analysis, as well as new industrial facilities
which are expected to be built in the future. The Company estimates that there
are several thousand web-type material production lines, many of which the
Company believes have obsolete measurement and control systems, which could be
upgraded by incorporating the Company's on-line finished materials quality
control systems. The Company believes that the current total annual worldwide
market for process optimization instruments and systems is in excess of $2
billion. The Company believes its process optimization products and systems
currently address an approximately $500 million annual market segment.
 
     The Company's strategy is to capitalize on the large market opportunities
for advanced measurement systems in the basic materials industries and to
exploit its core competencies and proprietary technologies through an evolving
series of optimization systems. As part of this strategy, the Company intends to
expand the geographic scope of its addressed markets. In particular, the Company
intends to expand the market presence of its on-line finished materials quality
control products in Asia, the U.S. and Latin America by drawing on the global
market expertise and existing global sales force of its on-line raw
 
                                       17
<PAGE>   18
 
materials analyzer business. In addition, the Company intends to aggressively
pursue market opportunities for its on-line raw materials analyzer products
created by the rapid infrastructure development and new manufacturing capacity
occurring in Asia and Latin America. Further, the Company intends to pursue
opportunities to retrofit the large existing base of coal mines, coal-burning
utilities and cement plants with its on-line process optimization systems. The
Company also intends to target new industries such as the pharmaceutical,
agrochemical, industrial chemical and glass industries. For example, the Company
is developing a laser-based spectroscopy system to be used on-line to analyze
the complex molecular structures of chemicals, which the Company believes can be
adapted for use in the pharmaceutical industry. The Company also plans to make
strategic acquisitions of complementary businesses. On December 31, 1996, the
Company acquired substantially all of the assets, subject to certain
liabilities, of the Autometrics division of Svedala Industries, Inc. Autometrics
designs, manufactures and markets on-line analysis instruments for the minerals
processing industry.
 
     In January 1993, Thermo Instrument acquired Gamma-Metrics, a manufacturer
and marketer of on-line raw materials analyzers and in October 1993, Thermo
Instrument acquired all of the assets, subject to certain liabilities, of
Radiometrie, a manufacturer and marketer of on-line finished materials quality
control systems. Gamma-Metrics and Radiometrie operated as two divisions of
Thermo Instrument until the Company's incorporation as a Delaware corporation in
November 1996. In connection with the Company's incorporation, Thermo Instrument
transferred to the Company the assets, liabilities and businesses of the
Gamma-Metrics subsidiary and Radiometrie division in exchange for 5,000,000
shares of the Company's common stock. In December 1996, the Company acquired the
Autometrics business. The Company's on-line raw materials analyzer business is
conducted by its Gamma-Metrics subsidiary based in San Diego, California, and
its on-line finished materials quality control business is conducted by its
Radiometrie division with operations in Erlangen, Germany and Gloucester,
England. The Company's principal executive offices are located at 5788 Pacific
Center Boulevard, San Diego, California 92121, and its telephone number is (619)
450-9649.
 
     On-line Raw Materials Analyzer Business
 
     The Company manufactures on-line process optimization systems which
non-invasively measure and analyze the physical and chemical properties of a
stream of bulk solid materials in real-time. The systems are primarily used to
analyze the composition of raw materials used in certain basic industries, such
as coal, cement and minerals. The analysis technique used in the Company's
process optimization systems involves neutron interrogation. Under neutron
interrogation each element, when activated by neutrons, emits gamma rays of
unique characteristics which allow identification and quantification of the
elements present. Neutron interrogation has a major advantage over other on-line
measuring technologies such as x-rays because neutrons can deeply penetrate the
materials being analyzed. As a result, neutron interrogation allows the entire
stream of the material to be analyzed and eliminates the need for sampling. In
addition, it provides a more accurate analysis of the materials, especially
non-homogeneous materials, and can be used to analyze an extremely broad range
of materials. The systems contain proprietary sensors that detect gamma rays
emitted from the material being analyzed, which is activated by the neutron
source within the analyzer, yielding a composite gamma ray spectrum of the
material analyzed. Through on-line high speed spectroscopy, this spectrum is
then decomposed into its constituent parts by using microprocessors and
sophisticated real-time analytical software. The analyzer can then translate
this data into the elemental composition of the raw materials and can also use
the information to infer certain quality control parameters specific to the
process.
 
     The Company has developed extensive proprietary know-how and expertise
regarding the measuring capabilities of various on-line sensor technologies
based on the material being analyzed and the ultimate use of the material. The
Company draws on this expertise to modify and adapt its technology to maximize
the efficiency and performance of its sensors in each application. The Company's
systems also employ ultra-high speed microprocessors and electronic signaling
devices which enable the technology to be used on-line and in real-time. The
Company has developed proprietary high speed sophisticated software which
rapidly processes the collected data and compares it to input target parameters.
In this way, a control signal can be generated which is then used to modify
process variables to guide the
 
                                       18

process to the target parameters. In order to provide real-time analysis, the
Company's systems must be integrated with the customer's production process,
thus subjecting them to hostile conditions. In response, the Company has
designed its systems to be extremely rugged, durable and accurate despite these
demanding conditions.
 
     Continuous on-line full-stream materials analysis provides faster and more
accurate analysis information than is possible with any conventional analysis
system. Traditional methods require numerous samples to be taken mechanically
from the materials at various stages of the production process, followed by
labor intensive sample preparation and laboratory analysis. Conventional
analysis techniques lag the production process and cannot be used effectively
for process control. In contrast, on-line, real-time analysis of the materials,
when coupled with the Company's software products, provides the customer with
immediate data regarding material composition and allows customers to
automatically and continuously adjust their manufacturing processes.
 
     The Company's systems can reduce operating costs through a decrease in raw
material waste and energy use. The continuous monitoring and adjustment of the
manufacturing process enable the customer to use its raw materials more
efficiently. Product quality and consistency are also improved with use of the
Company's systems. For example, one typical application enables customers in the
cement industry to regulate closely the raw mix proportions of cement materials
to produce a more consistent product. Customers building new facilities can save
on capital outlay by reducing their investment in homogenizing
stacker/reclaimers and homogenizing silos, the traditional methods of
homogenizing raw materials. The Company's systems also reduce pollution,
optimize recycling and reduce material waste.
 
     The Company currently markets the following family of products based on its
neutron interrogation technology.
 
     On-line Coal Analyzer.  The Company's on-line coal analyzer analyzes
streams of coal at a rate of up to four hundred tons per hour. The analyzer uses
neutron interrogation to determine the sulfur and ash concentration of the coal
on a continuous basis, and can also simultaneously compute the calorific value
of the coal, among other quality parameters. Customers can use the data to blend
or sort the coal depending on its quality. The Company has developed proprietary
high speed software that can be incorporated into the system to enable the
customer to automatically adjust and control the coal blending and sorting
process on-line.
 
     Coal analyzers are currently used by coal mines and coal-burning utilities.
Increased competition in the coal industry has forced coal producers to reduce
costs while meeting increasingly stringent quality specifications. Coal mines
can use the coal analyzer to improve profitability by blending coals of
different quality to meet specific contract requirements or environmental
regulatory standards, by sorting out low sulfur coal which can be sold for a
premium or by controlling the specific gravity of separation in a coal cleaning
plant to ensure that quality specifications are met without over-cleaning. In
addition to ensuring more consistent quality, on-line coal analysis improves
recovery or yield from the mine, thus extending the life of a mine by reducing
the risk of premature exhaustion of low sulfur reserves that are required to
balance high sulfur reserves. Utility market deregulation and privatization,
coupled with environmental emission standards, has forced coal-burning utilities
to reduce costs while satisfying environmental emissions regulations.
Coal-burning utilities benefit from using on-line coal analyzers by enabling the
utility to accurately and rapidly test the coal to verify that the specification
of coal received under contract meets its specifications; to burn a more
cost-effective blend of high and low sulfur coal without violating environmental
emissions standards; to avoid investment in costly scrubbers; to generate
emission credits by controlling emissions; to improve boiler performance by
burning consistent quality coal; and to provide data verification of continuous
emission monitors.
 
     Fifty-five percent of electricity production today in the U.S. is derived
from coal, and coal is the primary source of electricity in the rest of the
world. Further, it is estimated that approximately 45 new coal mines and
coal-burning utilities will be built each year for the next several years. In
China alone it is estimated that over 140 coal-fired utility plants will be
built between 1995 and 2005. The price of an on-line coal analyzer system ranges
from $300,000 to $500,000.
 
                                       19

     CrossBelt Analyzer.  The Company's CrossBelt Analyzer ("CBA") is used
primarily by the cement industry to analyze the composition of cement raw
materials. The CBA is essentially a horizontal tunnel that is easily assembled
around the customer's conveyor belt. The CBA analyzes materials traveling on a
conveyor belt at speeds of up to 600 feet (200 meters) per minute and with
material flow rates in excess of 1,000 tons per hour. The CBA generates data
which provides the elemental composition of the entire stream of materials and
can also use the information to infer certain quality control parameters, such
as lime saturation factor and silica ratio. The CBA can incorporate high speed
proprietary software which allows the customer to automatically control
production processes.
 
     Cement producers purchase the CBA to improve the economics of the plant by
reducing operating costs through the reduction in material waste and fuel costs.
The CBA is incorporated on-line into the customer's production process, which
enables the customer to control the mix of raw materials at the beginning of the
production line or to automatically control the blending of the cement additives
with crushed limestone and clay further down the production line. Both
approaches enable the producer to achieve more uniform cement quality. The CBA
controls the production process by using the analytical data it compiles to
automatically adjust the composition of the additive mix to achieve target
quality levels. This approach helps reduce variations in the materials fed into
the cement kiln yielding several benefits: lower energy consumption in the
cement mills, greater throughput and extended refractory life. Some customers
have reported that the use of the CBA has resulted in the reduction of fuel
costs. Fuel costs can constitute a significant percentage of a cement plant's
overall operating costs. For new plants, reduced variations in raw material
chemistry can also translate into major savings in the capital outlay for
homogenizing stacker/reclaimers and for homogenizing silos. This homogenizing
equipment is used to blend uneven raw materials. The price of a CBA system
ranges from $700,000 to $1 million.
 
     The annual consumption of cement is expected to rise from the 1994 figure
of approximately 1.3 billion tons to approximately 1.8 billion tons by the year
2005. In addition, there are currently approximately 1,150 cement plants that
the Company has identified as potential customers for its CBA.
 
     Mineral Slurry Analyzers.  The Company recently developed an on-line
analyzer using neutron interrogation for use in the mineral extraction industry
for analyzing mineral slurry, a mixture of fine insoluble materials and water.
The Company has successfully tested its neutron-based mineral slurry analyzer at
a beta test site. Virtually all mined minerals, including iron, copper, nickel
and bauxite, must be separated and purified through a process called
beneficiation whereby the mined minerals are milled and mixed with water to form
a mineral slurry. The mineral of interest is then concentrated through a variety
of separation stages using reagents. The Company's neutron-based mineral slurry
analyzer, which analyzes the entire elemental composition of the slurry, can
greatly improve the efficiency of the beneficiation process by using the
collected data to automatically adjust various process parameters, including the
amount of reagents used in the process. The Company believes its neutron-based
mineral slurry analyzer is suitable for controlling the beneficiation process
for a wide variety of minerals.
 
     On December 31, 1996, the Company acquired substantially all of the assets,
subject to certain liabilities, of Autometrics. Autometrics is a manufacturer of
mineral slurry analyzers. The assets acquired included two complementary product
lines and a customer base of approximately 300 customers, the majority of which
are located in the U.S. The two product lines acquired were Autometrics' on-line
x-ray slurry analyzers and its on-line particle size analyzers.
 
     The x-ray slurry analyzers are used in the mineral extraction industry,
primarily for copper, iron and gold extraction, to measure the percentage of
elements present in mineral slurries and can be designed to automatically
control and adjust the amount of reagents used in the mineral beneficiation
process. The x-ray slurry analyzer uses x-ray fluorescence as its energy source
which is a less expensive energy source than neutron interrogation, and does not
penetrate the materials being analyzed as deeply as neutron interrogation. The
x-ray slurry analyzer provides customers, who do not require a comprehensive
analysis system, a cost-effective alternative to the Company's neutron-based
mineral slurry analyzer.
 
     The on-line particle size analyzers are on-line real-time particle size
measuring instruments which have been used for over 15 years in the mineral
extraction industry. The on-line particle size analyzers use
 
                                       20
<PAGE>   21
 
ultrasound together with proprietary models to determine the particle size
distribution and percent solids in mineral slurries.
 
     The price of the Company's mineral slurry analyzers ranges from $50,000 to
$500,000. The Company believes there are currently approximately 750 mineral
processing facilities worldwide for all of the Company's products.
 
     Software Products.  The Company complements its application specific sensor
technology with process optimization software. These systems use adaptive and
predictive controls to maximize material utilization, as well as to blend raw
materials to meet certain regulatory requirements in a cost-effective manner.
The process to extract, beneficiate and utilize raw materials is difficult to
control due to variances in chemistry, size and shape of the materials, and time
delays in the transport of materials from different points within the handling
system. Traditional process control methods cannot be utilized in these dynamic
and highly variable conditions. The Company's proprietary process control
software can accomplish these optimization tasks by performing model-based
estimation and by adaptively controlling source materials. The Company is the
only provider of process control software of this type for use by customers in
the raw materials segment of the basic materials industry.
 
     A variety of products are manufactured and sold by the Company to address
the disparate needs of the cement, coal and energy industries. For the cement
industry, RAMOS(TM) achieves continuous blending for up to six sources of bulk
materials and three control parameters, while PREBOS(TM) is ideal for batch
blending, employing up to twelve sources. COBOS(TM) is used by coal producers
and coal-fired utilities to blend coal to a target composition defined by
sulfur, ash or calorific value and thus achieve optimum fuel composition while
meeting emission limits.
 
     FastLab.  The Company also offers its FastLab analyzer for rapid analysis
of samples off-line, with minimal sample preparation. The FastLab can be used
for numerous applications such as spot check analysis of raw materials, core
hole analysis, fuel analysis and chemical additives analysis. This product is
suitable for the same markets which use on-line elemental analysis. Its
advantages include its ease of use, its flexibility in handling multiple
material types and sampling locations and its low cost. The price of the
Company's FastLab analyzer ranges from $250,000 to $400,000.
 
     Process Safety Instrumentation.  Prior to entering the on-line process
optimization systems business, the Company's principal business was process
safety instrumentation for the nuclear power industry. The Company is a leading
supplier of process safety instrumentation in this industry. The Company's
instrumentation is designed to improve the safety and efficiency of nuclear
power plants. The Company produces several products for this market ranging in
price from $100,000 to $2.5 million. In addition, the Company offers automated
test equipment and some safety-related computer software for nuclear power
plants and other facilities where radioactive materials are used.
 
     On-line Finished Materials Quality Control Business
 
     The Company develops, manufactures and markets gauges and process
optimization systems for industrial manufacturing lines for continuous
production of certain web-type materials. Web-type materials are flat sheet
materials like paper, metal strip, plastic foil, rubber and glass. Typical high
volume products made from web-type materials include all types of vehicle body
and other parts, metals used for refrigerators and similar products,
beverage/food cans, cladding for buildings and rubber tires. The Company's
instruments measure the total thickness, basis weight and coating thickness of
web-type materials such as plastic foils, hot and cold metal strip, rubber,
glass and non-woven fabrics. The measuring technology incorporated in the
Company's products is based on partial absorption, reflection or change in
ionizing or infra-red radiation as well as of white light and laser beams, by
the materials to be measured. The Company's systems can measure a single point
on the material to be measured, several points or generate a "profile" of the
web. Measured values are acquired without contact and without interfering with
the production process, have high measurement accuracy and are extremely
reliable despite hostile environments. The Company offers its measuring gauges
with or without its process optimization systems. The customer's production
process can be regulated automatically by the Company's process optimization
system.
 
                                       21
<PAGE>   22
 
     The Company's products incorporate a variety of measurement gauges such as
x-ray thickness gauges, isotope thickness gauges, x-ray fluorescence coating
gauges or beta-backscatter gauges, depending on the application. One of the
Company's strengths is its proprietary know-how regarding application-specific
technology. The thickness gauges manufactured by the Company basically function
by measuring partial absorption of energy by the material to be measured. The
change in the intensity of the energy emitted is detected by application
specific sensors, then processed by high speed microprocessors, before emerging
as the measured value. These instruments can incorporate the Company's high
speed proprietary software to form a fully integrated process optimization
system for continuous manufacturing processes and improved product quality. The
Company's Fuzzy-Neurocontrol(TM) software provides predictive adaptive control
of the process. This proprietary software allows a more timely control of the
process, adapts the controls to the varying conditions in the process and offers
improved material savings. The Company's Spectracomp(TM) software automatically
and continuously compensates for variations in metal thickness measurements
resulting from changes in the composition of the alloy being measured.
 
     Competitive pressures have necessitated that producers of web-type
materials reduce production costs. The Company's products not only save on raw
materials and energy but they also maximize productivity and product quality.
The total thickness of web-type material, or the coating on it, is measured
accurately at the point of manufacture by the Company's products and are
compared by the system with an input target value. Adjustments can be made to
the manufacturing process early in the process, thereby reducing material waste.
The Company's systems also provide several competitive advantages which afford
the customer additional cost savings. For example, the Company's products can
accurately measure materials closer to the edge of the strip thus reducing
material waste. The Company has developed a reputation for rugged and reliable
instruments that can withstand hostile conditions. Ruggedness is critical to
customers because the Company believes downtime of the production system could
cost a customer up to $100,000 an hour. The Company's proprietary hot gauges can
be placed closer to the actuator (air knife) than conventional cold gauges
allowing adjustments earlier in the production process thus decreasing material
waste. In addition, the Company's systems include an extremely short response
time gauge, sending control signals one inch(2.5 centimeters) after measurement,
while competitors' gauges typically require at least twice this distance. Costs
can also be reduced through reduced start-up and product change times using the
system's comprehensive organized display of the process parameters. Reducing
start-up times at the beginning of the production and product change saves
energy, reduces scrap and saves machine time. Depending on the circumstances,
most customers can recoup their investment in a Company system within six to
eighteen months of installation. Prices for the Company's gauges and process
optimization systems typically range from $50,000 to $1 million. Competitive
technologies enabling on-line measurement of the thickness, such as contacting
mechanical thickness gauges and pneumatic calipers, exist, however, the Company
believes that use of these technologies results in inferior accuracy when
compared with its own products.
 
     The Company believes there is significant market potential for its products
resulting from several factors including increased demand for on-line
optimization, growing market opportunities in Asia and Latin America, increased
market penetration in the U.S. and the expansion of steel minimills. The Company
estimates that there are currently several thousand production lines worldwide
that currently use or could benefit from on-line process optimization. Asia and
Latin America are experiencing growth in infrastructure development and
manufacturing capacity which will drive demand for the Company's systems. The
Company also believes there are potential opportunities to penetrate the U.S.
markets which are dominated by few competitors. End users in the U.S. are
demanding alternative sources of on-line process optimization. Increased
emphasis on energy efficiency will also create demand for the Company's
products. For example, in the automotive industry, for a given load-carrying
capacity, all types of vehicles are being designed with a lower mass, with the
objective of reducing energy consumption. This leads directly to several trends:
for example, mass-produced road vehicles will use less steel and be made of
thinner steels, plastic sheet parts and even aluminum. (The Audi A8, for example
has an aluminum body.) Likewise, aircraft parts will be fabricated from more
exotic materials
 
                                       22
<PAGE>   23
 
such as composites and titanium. These trends indicate lower volume but higher
value manufacture of web-type products and, consequently, increased demand for
the Company's gauges and process optimization systems. The expansion of steel
minimills (recycling) has created competitive pressures in the steel industry
through increased demand for efficiency, which in turn will also stimulate
demand for the Company's gauges and process optimization systems.
 
COMPETITION
 
     In the coal, cement and mineral industries, the Company competes primarily
on performance and to a lesser extent on price. Competition regarding on-line
coal and cement analyzers is limited at present. Scantech Limited (formerly
Mineral Control Instrumentation Ltd.) of Australia is the Company's principal
competitor in the on-line coal analyzer market. Scantech Limited, which entered
the cement industry market in 1993, is also the Company's principal competitor
in this industry. The Company is a recent entrant into the on-line mineral
slurry analyzers market where it competes primarily with Amdel of Australia. The
market for solids and multiphase analyzers for process control generally is
fragmented, with numerous competitors. The Company believes it is a market
leader in the segment of the solids and multiphase analyzer market for on-line
bulk materials analyzers using neutron interrogation.
 
     Competition in the thickness gauging business is highly fragmented with
numerous competitors competing in various end use market segments. As a result,
competition varies according to the end use segment. The Company competes by
quality, performance and price. The Company's largest competitor is Honeywell,
through its recent acquisition of Measurex (USA), which in turn recently
acquired Data Measurement Corporation, the metals gauging division of Loral and
Ohmart. Both Data Measurement and Loral offer systems to the metals industry.
Ohmart is a supplier mainly to the plastics industry. Toshiba and Yokoyawa
(Japan) are at present competing with the Company in Asia. IMS (Germany) and IRM
(Belgium/USA), (formerly the metal gauging division of ABB (Sweden/Switzerland))
compete with the Company worldwide in the metals industry. There are a number of
competitors such as NDC (US), Eurotherm (UK) and Infrared Engineering (UK) which
compete with the Company in the plastics and rubber industry.
 
     Certain of the Company's competitors have greater resources, manufacturing
and marketing capabilities, technical staff and production facilities than those
of the Company. As a result, they may be able to adapt more quickly to new or
emerging technologies and changes in customer requirements, or to devote greater
resources to the promotion and sale of their products than can the Company.
Further, competition with respect to all of the Company's products could
increase if new companies enter the market or if existing competitors expand
their product lines. There can be no assurance that competitors of the Company
will not develop technological innovations that will render products of the
Company obsolete.
 
MARKETING, SALES AND DISTRIBUTION
 
     On-line Raw Materials Analyzer Business.  The Company sells its on-line raw
material analyzer products directly to its customers worldwide through its sales
force consisting of 11 persons. The territories of this sales force are
primarily geographical with some segment specialization. In addition, the
Company uses a network of sales and service representatives in 23 countries
around the world to facilitate product distribution worldwide. The primary
function of these representatives is to stay in close contact with customers or
potential customers, gather market information, translate, advertise,
participate in trade shows, arrange meetings and facilitate logistics. The
Company also sells some products to original equipment manufacturers ("OEMs")
who offer the Company's products along with their own or a third party's
products. Sales to OEMs represent approximately 10% of the Company's total
revenues.
 
     On-line Finished Materials Quality Control Business.  The Company sells its
on-line finished materials quality control systems primarily in Europe through a
direct sales force of 20 employees, and through a network of 14 distributors and
sales representatives in Europe. In Asia, a sales network is being established
with three agents currently under contract covering China, India and Japan.
Recently, the Company has employed three agents in Latin America covering
Argentina, Brazil and Colombia. In November 1996, an area sales manager was
hired to establish a sales operation addressing countries
 
                                       23
<PAGE>   24
 
participating in NAFTA. In addition, the Company sells its products to OEMs.
Sales to OEMs represented approximately one-third of the Company's total
revenues from its on-line finished materials quality control business for 1996.
The Company intends to further extend its sales network in Asia, North America
and Latin America.
 
     Customer Service and Support.  The Company believes that high quality
customer service and support is critical to success in the process optimization
segment of the analytical instrumentation industry. The Company maintains a
staff of engineers to assist customers with installing and integrating their
process optimization system and to provide ongoing spare parts and calibration
services for its on-line raw materials analyzer business. In addition, modems
permit remote diagnostics by customer support personnel from the Company's
headquarters or from satellite support centers. The Company supports its
manufacturing operations for its on-line finished materials quality control
business with a full range of services including application and engineering
support, installation, supervision, commissioning, emergency field service by
remote diagnostics via modems, extensive customer training, consulting and spare
parts.
 
RESEARCH AND DEVELOPMENT
 
     The Company maintains active programs for the development and introduction
of new products and improvements to existing products. The Company also seeks to
develop new applications for its existing products and technology. In
particular, the Company is actively seeking new applications for its non-
invasive, non-destructive analysis technologies. The Company is also in the
process of developing other applications for its CBA.
 
     With respect to its on-line finished materials quality control business,
the Company is focused on two areas of commercial importance in the metals
industry, the measurement of metal coatings and the cross-profile thickness
measurement of hot steel strip, cold strip and plate. In both areas of
measurement, parameters, particularly accuracy and resolution, are being
tightened in response to end-user needs. In addition, the Company is involved in
numerous other development projects including, among others, development of an
x-ray based tomographic thickness profile system. The object of this system is
to take a snapshot of thickness variations across the sheet at a high transverse
resolution. This system is in the early stages of development. The Company is
also developing a compact fixed energy x-ray source for thin films in the
plastic, rubber, glass and other industries which the Company anticipates
introducing to the market in 1997.
 
     Research and development expenses for the Company were $2.3 million, $2.6
million, $3.0 million and $2.1 million in fiscal 1994, 1995 and 1996, and the
six months ended June 28, 1997, respectively. As of September 27, 1997, the
Company had 32 full time employees engaged in research and development.
 
PATENTS
 
     The Company's policy is to protect its intellectual property rights and to
apply for patent protection when appropriate. The Company is the owner of 12
United States patents as well as corresponding foreign patents having expiration
dates ranging from 1998 through 2014. Patent protection is believed to provide
the Company with competitive advantages with respect to certain instruments. The
Company also considers that technical know-how, trade secrets and trademarks are
important to its business.
 
     There can be no assurance that any patents now or hereafter owned by the
Company will afford protection against competitors. Proceedings initiated by the
Company to protect its proprietary rights could result in substantial costs to
the Company. Recently, the Company's Gamma-Metrics subsidiary initiated a
lawsuit in the Federal District Court in San Diego, California, alleging, among
other things, patent infringement against Scantech Limited and its subsidiary
Mineral Control Instrumentation Ltd. There can be no assurance that competitors
of the Company, some of whom have substantially greater resources than those of
the Company, will not initiate litigation to challenge the validity of the
Company's patents, use their resources to design comparable products that do not
infringe the Company's patents or initiate claims that the Company's products
infringe the competitors' patents. The Company could incur substantial costs and
diversion of management resources with respect to the defense of any such
 
                                       24
<PAGE>   25
 
challenges or claims, which could have a material adverse effect on the
Company's business, financial condition, and results of operation. Furthermore,
parties making such challenges or claims could secure a judgment awarding
substantial damages, as well as injunctive or other equitable relief, which
could effectively block the Company's ability to make, use, sell, distribute or
market its products and services in the U.S. and abroad. See "Risk Factors --
Proprietary Rights."
 
FACILITIES
 
     The Company's various businesses are operated from separate facilities. The
Company leases approximately 45,000 square feet in San Diego, California
pursuant to a lease that expires in 2003. The Company uses this facility for
manufacturing, sales and administration for its on-line raw materials analyzer
business. The Company also leases approximately 20,000 square feet in
Gloucester, England, pursuant to a lease expiring in 2001, and owns an
approximately 100,000 square foot facility in Erlangen, Germany, of which
approximately 45,300 square feet are utilized by the Company, with the balance
being used by another Thermo Instrument company. Both of these facilities are
used by the Company for manufacturing, sales and administration for its on-line
finished materials quality control business. In addition, the Company leases
office space throughout the world for its sales and service operations. The
Company believes that these facilities are adequate for its present operations.
 
PERSONNEL
 
     As of September 27, 1997, the Company had a total of 317 employees, of whom
51 were engaged in research and product development and 266 were engaged in
sales, service, manufacturing and general management. The Company has had no
work stoppages and considers its relations with employees to be good.
 
BACKLOG
 
     The Company's backlog of firm orders was approximately $29.2 million and
$27.8 million at June 29, 1996 and June 28, 1997, respectively. The Company
includes in backlog only those orders for which it has received firm purchase
orders and for which delivery has been specified within twelve months. Because
of the possibility of customer changes in delivery schedules, cancellation of
orders and potential delays in product shipments, the Company's backlog as of
any particular date may not be representative of actual sales for any succeeding
period.
 
RAW MATERIALS
 
     Various components of the Company's products are supplied by sole-source
vendors. The Company has not experienced significant difficulty in obtaining
adequate supplies from these vendors, and has identified alternate suppliers.
However, there can be no assurance that the unanticipated loss of a single
vendor would not result in delays in shipments or the introduction of new
products.
 
SEASONALITY
 
     The Company's on-line finished materials quality control business
experiences a slowdown in revenues during the first quarter of each calendar
year primarily because its customers tend to place their orders earlier in the
year so that they can have the systems installed either during the holiday
season in the third quarter or between Christmas and the New Year.

                       RELATIONSHIP WITH THERMO ELECTRON
                             AND THERMO INSTRUMENT
 
     Thermo Electron has adopted a strategy of selling a minority interest in
subsidiary companies to outside investors as an important tool in its future
development. As part of this strategy, Thermo Instrument has created the Company
as a privately held subsidiary, and Thermo Instrument and Thermo Electron, and
certain of their subsidiaries, have created several other privately and publicly
held majority-owned subsidiaries. From time to time, Thermo Electron and its
subsidiaries will create other majority-owned subsidiaries as part of its
spin-out strategy. (The Company and the other Thermo Electron subsidiaries are
hereinafter referred to as the "Thermo Subsidiaries.")
 
     Thermo Instrument develops, manufactures, and markets analytical
instruments used to detect and monitor air pollution, radioactivity, complex
chemical compounds and toxic metals and other elements in a broad range of
liquids and solids. For its fiscal year ended December 30, 1995 and December 28,
1996 and the six months ended June 28, 1997, Thermo Instrument had consolidated
revenues of $782,662,000, $1,209,362,000 and $734,355,000, respectively, and
consolidated net income of $79,306,000, $132,751,000 and $70,806,000,
respectively.
 
     Thermo Electron and its subsidiaries develop, manufacture and market
environmental monitoring and analysis instruments and manufacture biomedical
products including heart-assist devices and mammography systems, papermaking and
recycling equipment, alternative-energy systems and other specialized products
and technologies. Thermo Electron and its subsidiaries also provide
environmental and metallurgical services and conduct advanced technology
research and development. For its fiscal year ended December 30, 1995 and
December 28, 1996 and the six months ended June 28, 1997, Thermo Electron had
consolidated revenues of $2,270,291,000, $2,932,558,000 and $1,638,521,000,
respectively, and consolidated net income of $139,582,000, $190,816,000 and
$108,216,000, respectively.
 
THE THERMO ELECTRON CORPORATE CHARTER
 
     Thermo Electron and the Thermo Subsidiaries, including the Company,
recognize that the benefits and support that derive from their affiliation are
essential elements of their individual performance. Accordingly, Thermo Electron
and each of the Thermo Subsidiaries adopted the Thermo Electron Corporate
Charter (the "Charter") to define the relationships and delineate the nature of
such cooperation among themselves. The purpose of the Charter is to ensure that
(1) all of the companies and their stockholders are treated consistently and
fairly, (2) the scope and nature of the cooperation among the companies, and
each company's responsibilities, are adequately defined, (3) each company has
access to the combined resources and financial, managerial and technological
strengths of the others, and (4) Thermo Electron and the Thermo Subsidiaries, in
the aggregate, are able to obtain the most favorable terms from outside parties.
 
     To achieve these ends, the Charter identifies the general principles to be
followed by the companies, addresses the role and responsibilities of the
management of each company, provides for the sharing of group resources by the
companies and provides for centralized administrative, banking and credit
services to be performed by Thermo Electron. The services provided by Thermo
Electron include collecting and managing cash generated by members, coordinating
the access of Thermo Electron and the Thermo Subsidiaries (the "Thermo Group")
to external financing sources, ensuring compliance with external financial
covenants and internal financial policies, assisting in the formulation of
long-range planning and providing other banking and credit services. Pursuant to
the Charter, Thermo Electron may also provide guarantees of debt obligations of
the Thermo Subsidiaries or may obtain external financing at the parent level for
the benefit of the Thermo Subsidiaries. In certain instances, the Thermo
Subsidiaries may provide credit support to, or on behalf of, the consolidated
entity or may obtain financing directly from external financing sources. Under
the Charter, Thermo Electron is responsible for determining that the Thermo
Group remains in compliance with all covenants imposed by external financing
sources, including covenants related to borrowings of Thermo Electron or other
members of the Thermo Group,
 
                                       26
<PAGE>   27
 
and for apportioning such constraints within the Thermo Group. In addition,
Thermo Electron is also responsible for ensuring that members comply with
internal policies and procedures. The cost of the services provided by Thermo
Electron to the Thermo Subsidiaries is covered under existing corporate services
agreements between Thermo Electron and each of the Thermo Subsidiaries.
 
     The Charter presently provides that it shall continue in effect so long as
Thermo Electron and at least one Thermo Subsidiary participates. The Charter may
be amended at any time by agreement of the participants. Any Thermo Subsidiary,
including the Company, can withdraw from participation in the Charter upon 30
days' prior notice. In addition, Thermo Electron may terminate a subsidiary's
participation in the Charter in the event the subsidiary ceases to be controlled
by Thermo Electron or ceases to comply with the Charter or the policies and
procedures applicable to the Thermo Group. A withdrawal from the Charter
automatically terminates the corporate services agreement in effect between the
withdrawing company and Thermo Electron. The withdrawal from participation does
not terminate outstanding commitments to third parties made by the withdrawing
company, or by Thermo Electron or other members of the Thermo Group, prior to
the withdrawal. However, a withdrawing company is required to continue to comply
with all policies and procedures applicable to the Thermo Group and to provide
certain administrative functions mandated by Thermo Electron so long as the
withdrawing company is controlled by or affiliated with Thermo Electron.
 
CORPORATE SERVICES AGREEMENT
 
     As provided in the Charter, the Company and Thermo Electron have entered
into a Corporate Services Agreement (the "Services Agreement") under which
Thermo Electron's corporate staff provides certain administrative services,
including certain legal advice and services, risk management, certain employee
benefit administration, tax advice and preparation of tax returns, centralized
cash management and certain financial and other services to the Company. The
annual fee for these services was equal to 1.2% of the Company's revenues for
calendar 1995. Beginning January 1, 1996, the fee was reduced to 1% of the
Company's revenues. The fee is reviewed annually and may be changed by mutual
agreement of the Company and Thermo Electron. During fiscal 1995 and 1996,
Thermo Electron assessed the Company fees of $552,000 and $520,000,
respectively.
 
     Management believes that the service fees charged under the Services
Agreement are reasonable and that the terms of the Services Agreement are fair
to the Company. For items such as employee benefit plans, insurance coverage and
other identifiable costs, Thermo Electron charges the Company based on charges
directly attributable to the Company. The Services Agreement automatically
renews for successive one-year terms, unless canceled by the Company upon 30
days' prior written notice. In addition, the Services Agreement terminates
automatically in the event the Company ceases to be a member of the Thermo Group
or ceases to be a participant in the Charter. In the event of a termination of
the Services Agreement, the Company will be required to pay a termination fee
equal to the fee that was paid by the Company for services under the Services
Agreement for the nine-month period prior to termination. Following termination,
Thermo Electron may provide certain administrative services on an as-requested
basis by the Company or as required in order to meet the Company's obligations
under Thermo Electron's policies and procedures. Thermo Electron will charge the
Company a fee equal to the market rate for comparable services if such services
are provided following termination.
 
MASTER GUARANTEE REIMBURSEMENT AGREEMENTS
 
     The Company has entered into a Master Guarantee Reimbursement Agreement
with Thermo Electron which provides that the Company will reimburse Thermo
Electron for any costs it incurs in the event it is required to pay third
parties pursuant to any guarantees it issues on the Company's behalf. Thermo
Instrument has entered into a similar agreement with Thermo Electron with regard
to the Company's obligations which are guaranteed by Thermo Electron. The
Company has also entered into a Master Guarantee Reimbursement Agreement with
Thermo Instrument which provides that the Company will reimburse Thermo
Instrument for any costs it incurs in the event that Thermo Instrument is
required to pay Thermo Electron or any other party pursuant to any guarantees it
issues on the Company's behalf.

MISCELLANEOUS
 
     As of June 28, 1997, $49,585,000 of the Company's cash equivalents were
invested in a repurchase agreement with Thermo Electron. Under this agreement,
the Company in effect lends excess cash to Thermo Electron which Thermo Electron
collateralizes with investments principally consisting of corporate notes,
United States government agency securities, money market funds, commercial
paper, and other marketable securities, in the amount of at least 103% of such
obligation. The Company's funds subject to the repurchase agreement will be
readily convertible into cash by the Company. The repurchase agreement earns a
rate based on the 90-day Commercial Paper Composite Rate plus 25 basis points,
set at the beginning of each quarter.
 
     The Company leases approximately 54,700 square feet of its 100,000 square
foot facility in Erlangen, Germany on a month-to-month basis to another Thermo
Instrument company. The Thermo Instrument company is responsible for paying to
the Company its pro rata share of occupancy expenses, including utilities and
taxes, associated with the facility which payments in 1996 amounted to $368,000
in the aggregate.
 
     The Company has borrowed funds from a wholly owned subsidiary of Thermo
Optek Corporation ("Thermo Optek"), a majority-owned subsidiary of Thermo
Instrument, pursuant to certain promissory notes. The Company had $1,388,000 and
$1,928,000 outstanding under the promissory notes at year-end 1995 and 1996,
respectively. The notes bear interest at a variable rate. The interest rate for
the notes outstanding at year-end 1995 and 1996 was 4.6% and 3.8%, respectively.
The notes were repaid in February 1997. In addition, the Company had $3,617,000
and $2,611,000 of noninterest-bearing advances from Thermo Instrument and
affiliated companies at year-end 1995 and 1996, respectively, which were due on
demand. In December 1996, the Company borrowed $2,778,000 pursuant to a
noninterest-bearing advance from a wholly owned subsidiary of Thermo Instrument,
which was repaid on January 15, 1997. At June 28, 1997, the Company had
$1,284,000 of noninterest-bearing advances from Thermo Instrument and affiliated
companies, which are due on demand.
 
     In 1996, the Company paid a ten percent (10%) commission totaling $69,670
to Thermo Sentron Inc., a majority-owned subsidiary of Thermedics Inc., which is
in turn a majority-owned subsidiary of Thermo Electron, for assisting in the
sale by the Company of its products in Australia.
 
     In the first six months of 1997, the Company purchased several x-ray source
components for $129,000 from Kevex X-Ray Inc., a wholly owned subsidiary of
ThermoSpectra Corporation, which in turn is a majority-owned subsidiary of
Thermo Instrument.

     Directors Deferred Compensation Plan.  Under the Company's Deferred
Compensation Plan for Directors (the "Deferred Compensation Plan"), a Director
has the right to defer receipt of his fees until he ceases to serve as a
Director, dies or retires from his principal occupation. In the event of a
change in control or proposed change in control of the Company that is not
approved by the Board of Directors, deferred amounts become payable immediately.
Either of the following is deemed to be a change of control: (a) the occurrence,
without the prior approval of the Board of Directors, of the acquisition,
directly or indirectly, by any person of 50% or more of the outstanding Common
Stock or the outstanding common stock of Thermo Instrument or 25% or more of the
outstanding common stock of Thermo Electron; or (b) the failure of the persons
serving on the Board of Directors immediately prior to any contested election of
directors or any exchange offer or tender offer for the Common Stock or the
common stock of Thermo Instrument or Thermo Electron to constitute a majority of
the Board of Directors at any time within two years following any such event.
Amounts deferred pursuant to the Deferred Compensation Plan are valued at the
end of each quarter as units of Common Stock. When payable, amounts deferred may
be disbursed solely in shares of Common Stock accumulated under the Deferred
Compensation Plan. The Company has reserved 12,500 shares under this plan. As of
June 28, 1997, no stock options have been granted under this plan.

                           SUMMARY COMPENSATION TABLE
 
     The following table summarizes compensation for services to the Company in
all capacities awarded to, earned by or paid to the Company's chief executive
officer and two other executive officers for the fiscal year ended December 28,

Securities and Exchange Commission's executive compensation disclosure rules for
this period. The Company is required to appoint certain executive officers and
full-time employees of Thermo Electron as executive officers of the Company, in
accordance with the Thermo Electron Corporate Charter. The compensation for
these executive officers is determined and paid entirely by Thermo Electron. The

    Mr. Helm from all sources within the Thermo Electron organization and
    approve an allocation of a percentage of annual compensation (salary and
    bonus) for the time he devotes to the affairs of the Company. For 1996, none
    of Mr. Helm's annual compensation was allocated to the Company. In addition,
    Mr. Helm has been granted options to purchase common stock of Thermo
    Electron and certain of its subsidiaries other than the Company from time to
    time by Thermo Electron or such other subsidiaries. These options are not
    reported here as they were granted as compensation for service to Thermo
    Electron companies in capacities other than in his capacity as Chief
    Executive Officer of the Company.

(1) All options to purchase shares of the Common Stock of the Company
    (designated in the table as MKA) were granted after the end of fiscal 1996
    but are included in the table for clarity of presentation. All of the
    options granted during the fiscal year are immediately exercisable, except
    the options to purchase shares of the Common Stock of the Company, which are
    not exercisable until the earlier of (i) 90 days after the effective date of
    the registration of the Company's Common Stock under Section 12 of the
    Securities Exchange Act of 1934 and (ii) nine years after the grant date. In
    all cases, the shares acquired upon exercise are subject to repurchase by
    the granting corporation at the exercise price if the optionee ceases to be
    employed by such corporation or another Thermo Electron company. The
    granting corporation may exercise its repurchase rights within six months
    after the termination of the optionee's employment. For publicly traded
    companies, the repurchase rights generally lapse ratably over a five- to
    ten-year period, depending on the option term which may vary from seven to
    twelve years, provided that the optionee continues to be employed by the
    granting corporation or another Thermo Electron company. For companies that
    are not publicly traded, the repurchase rights lapse in their entirety on
    the ninth anniversary of the grant
 
                                       32

    date. The granting corporation may permit the holders of all such options to
    exercise options and satisfy tax withholding obligations by surrendering
    shares equal in fair market value to the exercise price or withholding
    obligation.
 
(2) The amounts shown on this table represent hypothetical gains that could be
    achieved for the respective options if exercised at the end of the option
    term. These gains are based on assumed rates of stock appreciation of 5% and
    10%, compounded annually from the date the respective options were granted
    to their expiration date. The gains shown are net of the option exercise
    price, but do not include deductions for taxes or other expenses associated
    with the exercise. Actual gains, if any, on stock option exercises will
    depend on the future performance of the Common Stock, the option holders'
    continued employment through the option period and the date on which the
    options are exercised.
 
(3) Mr. Helm has been granted options to purchase shares of the common stock of
    Thermo Electron and its subsidiaries other than the Company. These options
    are not reported in the table as they were granted as compensation for
    service in capacities other than Mr. Helm's capacity as Chief Executive
    Officer of the Company.
 
(4) These options were granted under stock option plans maintained by Thermo
    Electron companies other than the Company and accordingly are reported as a
    percentage of total options granted to employees of Thermo Electron and its
    subsidiaries.

(1) All options to purchase shares of the Common Stock of the Company were
    granted after the end of fiscal 1996 but are included in the table for
    clarity of presentation. All of the options reported outstanding at the end

    until the earlier of (i) 90 days after the effective date of the

     may vary from seven to twelve years, provided that the optionee continues
     to be employed by the granting corporation or another Thermo Electron
     company. For companies whose shares are not publicly traded, the repurchase

     The Shares are being registered to permit public secondary trading of the
Shares from time to time by the Selling Shareholders. All of the Shares being
offered by the Selling Shareholders were sold by the Company in private
placement transactions pursuant to Stock Purchase Agreements with the Company
dated December 16, 1996 and December 27, 1996 (the "Purchase Agreements") for
cash.
 
     In the Purchase Agreements, the Company agreed, among other things, to bear
all expenses (other than underwriting discounts, selling commissions, and fees
and expenses of counsel and other advisors to the Selling Shareholders) in
connection with the registration and sale of the Shares being offered by the
Selling Shareholders. See "Sale of Shares." The Company intends to prepare and
file such amendments and supplements to the Registration Statement of which this
Prospectus forms a part as may be necessary to keep the Registration Statement
effective until all the Shares registered thereunder have been sold pursuant
thereto or until, by reason of Rule 144(k) of the Commission under the
Securities Act or any other rule of similar effect, the Shares are no longer
required to be registered for the sale thereof by the Selling Shareholders.
 
                                 SALE OF SHARES
 
     The Company will not receive any of the proceeds from this offering. The
Shares offered hereby may be sold from time to time by or for the account of any
of the Selling Shareholders or by their pledgees, donees, distributees or
transferees or other successors in interest to the Selling Shareholders. The
Shares may be sold hereunder directly to purchasers by the Selling Shareholders
in negotiated transactions; by or through brokers or dealers in ordinary
brokerage transactions or transactions in which the broker solicits purchases;
block trades in which the broker or dealer will attempt to sell Shares as agent
but may position and resell a portion of the block as principal; transactions in
which a broker or dealer purchases as principal for resale for its own account;
or through underwriters or agents. The Shares may be sold at a fixed offering
price, which may be changed, at the prevailing market price at the time of sale,
at prices related to such prevailing market price or at negotiated prices. Any
brokers,
 
                                       38
<PAGE>   39
 
dealers, underwriters or agents may arrange for others to participate in any
such transaction and may receive compensation in the form of discounts,
commissions or concessions from the Selling Shareholders and/or the purchasers
of the Shares. Each Selling Shareholder will be responsible for payment of any
and all commissions to brokers.
 
     The aggregate proceeds to any Selling Shareholder from the sale of the
Shares offered hereby will be the purchase price of such Shares less any
broker's commission.
 
     In order to comply with the securities laws of certain states, if
applicable, the Shares will be sold in such jurisdictions only through
registered or licensed brokers or dealers. In addition, in certain states the
Shares may not be sold unless they have been registered or qualified for sale in
the applicable state or an exemption from the registration or qualification
requirement is available and is complied with.
 
     Any Selling Shareholder and any broker-dealer, agent or underwriter who
acts in connection with the sale of Shares hereunder may be deemed to be an
"underwriter" as that term is defined in the Securities Act, and any commissions
received by them and profit on any resale of the Shares as principal might be
deemed to be underwriting discounts and commissions under the Securities Act.
The Company has agreed to indemnify the Selling Shareholder against certain
liabilities, including liabilities under the Securities Act as underwriters or
otherwise.

                          DESCRIPTION OF CAPITAL STOCK
 
     As of October 21, 1997, the Company had 25,000,000 shares of Common Stock
authorized for issuance, of which 8,267,828 were issued and outstanding. Each
share of Common Stock is entitled to pro rata participation in distributions
upon liquidation and to one vote on all matters submitted to a vote of
stockholders. Dividends may be paid to the holders of Common Stock when and if
declared by the Board of Directors out of funds legally available therefor.
Holders of Common Stock have no preemptive or similar rights. The outstanding
shares of Common Stock and the shares offered hereby are legally issued, fully
paid and nonassessable.
 
     The shares of Common Stock have noncumulative voting rights, which means
that the holders of more than 50% of the shares voting can elect all the
Directors if they so choose, and in such event, the holders of the remaining
shares cannot elect any Directors. Thermo Instrument intends to continue to
beneficially own at least a majority of the outstanding Common Stock, and will
have the power to elect all of the members of the Company's Board of Directors.
 
     In May 1997, the Company declared and effected a one-for-two reverse stock
split pursuant to an amendment to its Certificate of Incorporation filed with
the Delaware Secretary of State on May 27, 1997. As a result, each share of
Common Stock outstanding immediately prior to such split was automatically
converted into one-half of a share of Common Stock. No fractional shares of
Common Stock were issued upon effectiveness of such split and all shareholders
otherwise entitled to fractional shares are entitled to cash in lieu of such
fractional share in the sum of such fractional share multiplied by $15.00.
 
     The Company's Certificate of Incorporation contains certain provisions
permitted under the General Corporation Law of Delaware relating to the
liability of Directors. The provisions eliminate a Director's liability for
monetary damages for a breach of fiduciary duty to the fullest extent permitted
by the General Corporation Law of Delaware. The Company's Certificate of
Incorporation also contains provisions to indemnify the Directors and officers
of the Company to the fullest extent permitted by the General Corporation Law of
Delaware. The Company believes that these provisions will assist the Company in
attracting and retaining qualified individuals to serve as Directors and
officers.
 
     The transfer agent and registrar for the Common Stock is American Stock
Transfer & Trust Company.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     There are currently 8,267,828 shares of Common Stock of the Company
outstanding, of which 3,267,828 are freely tradable without restriction or
further registration under the Securities Act, except that any shares purchased
by affiliates of the Company, as that term is defined in Rule 144 under the
Securities Act, may generally only be resold in compliance with applicable
provisions of Rule 144.
 
     Of such 8,267,828 outstanding shares, 5,000,000 are owned by Thermo
Instrument. In connection with the Company's initial public offering which was
completed June 24, 1997, Thermo Instrument has agreed that, without the prior
written consent of the Representatives (as defined below under the caption
"Underwriters"), it will not offer, sell, grant any option to purchase or
otherwise dispose of any shares of the Common Stock prior to December 22,1997,
other than (i) the issuance of options and sales of shares of Common Stock
pursuant to existing stock-based compensation plans, and (ii) shares of Common
Stock issuable upon the conversion of securities outstanding as of June 20,
1997. Upon expiration of this lock-up agreement, Thermo Instrument may sell its
shares of Common Stock in an offering registered under the Securities Act or
pursuant to an exemption from such registration. So long as Thermo Instrument is
able to elect a majority of the Board of Directors it will be able to cause the
Company at any time to register under the Securities Act all or a portion of the
Common Stock owned by Thermo Instrument or its affiliates, in which case it
would be able to sell such shares without restriction upon effectiveness of the
registration statement. In general, under Rule 144 as currently in effect, a
person (or persons whose shares are aggregated) who has beneficially owned
restricted shares for at least one year is entitled to sell, within any
three-month period, a number of such shares that does not exceed the greater of
(i) 1% of the then outstanding shares of Common Stock or (ii) the average weekly
 
                                       40
<PAGE>   41
 
trading volume in the Common Stock during the four calendar weeks preceding the
date of the notice filed pursuant to Rule 144. Sales under Rule 144 are also
subject to certain manner of sale restrictions and notice requirements and to
the availability of current public information about the Company. In addition, a
person who is deemed an "affiliate" of the Company must comply with Rule 144 in
any sale of shares of Common Stock not covered by a registration statement
(except, in the case of registered shares acquired by the affiliate on the open
market, for the holding period requirement). A person (or person whose shares

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Shareholders and Board of Directors of Metrika Systems Corporation:
 
     We have audited the accompanying consolidated balance sheet of Metrika
Systems Corporation (a Delaware corporation and 84%-owned subsidiary of Thermo
Instrument Systems Inc.) and subsidiaries as of December 30, 1995 and December
28, 1996, and the related consolidated statements of income, cash flows and
shareholders' investment for each of the three years in the period ended
December 28, 1996. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Metrika
Systems Corporation and subsidiaries as of December 30, 1995 and December 28,
1996, and the results of their operations and their cash flows for each of the
three years in the period ended December 28, 1996, in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.  NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Nature of Operations
 
     Metrika Systems (the "Company") develops, manufactures and markets on-line
industrial process optimization systems that employ proprietary ultra-high speed
advanced scientific measurement technologies for applications in raw materials
analysis and finished materials quality control. The Company manufactures
process optimization systems that provide real-time, non-destructive analysis of
the composition of raw materials in basic materials production processes,
including coal, cement and minerals. The Company also manufactures systems which
are used primarily to measure and control parameters such as material thickness,
coating thickness and coating weight in web-type materials, such as metal strip,
rubber and plastic foils. Customers use these systems to improve product quality
and consistency, lower material costs, reduce energy consumption and minimize
waste.
 
  Relationship with Thermo Instrument Systems Inc. and Thermo Electron
Corporation
 
     The Company operated as two divisions of Thermo Instrument Systems Inc.
("Thermo Instrument") until its incorporation as a Delaware corporation in
November 1996. In connection with the Company's incorporation, Thermo Instrument
transferred to the Company the assets, liabilities and businesses of the
Gamma-Metrics subsidiary and Radiometrie division in exchange for 5,000,000
shares of the Company's common stock. As of December 28, 1996, Thermo Instrument
owned 5,000,000 shares of the Company's common stock, representing 84% of such
stock outstanding. As of December 28, 1996, Thermo Instrument is a 82%-owned
subsidiary of Thermo Electron Corporation ("Thermo Electron").
 
     The accompanying financial statements include the assets, liabilities,
income and expenses of the Company as included in Thermo Instrument's
consolidated financial statements. The accompanying financial statements do not
include Thermo Instrument's general corporate debt, which is used to finance
operations of all of its respective business segments, or an allocation of
Thermo Instrument's interest expense. The Company had positive cash flow from
operations for all periods presented.
 
  Principles of Consolidation
 
     The accompanying financial statements include the accounts of the Company
and its wholly owned subsidiaries. All material intercompany accounts and
transactions have been eliminated.
 
  Fiscal Year
 
     The Company has adopted a fiscal year ending the Saturday nearest
December 31. References to 1994, 1995 and 1996 are for the fiscal years ended
December 31, 1994, December 30, 1995 and December 28, 1996, respectively.
 
  Revenue Recognition
 
     Generally, the Company recognizes product revenues upon shipment of its
products. The Company provides a reserve for its estimate of warranty and
installation costs at the time of shipment. Revenues and profits on contracts
which due to their complexity extend over multiple quarterly reporting periods
are recognized using the percentage-of-completion method. Such contracts include
all manufacturing contracts of the Company's on-line finished materials quality
control business which commonly are of 5-10 months duration as well as certain
contracts of similar duration or longer at the Company's on-line raw materials
analyzer business. Revenues recorded under the percentage-of-completion method
were $14,884,000 in 1994, $17,523,000 in 1995 and $18,611,000 in 1996. The
percentage of completion is determined by relating the actual costs incurred to
date to management's estimate of total costs to be incurred on each contract. If
a loss is indicated on any contract in process, a provision is made currently
for the entire loss. Contracts generally provide for the billing of customers
upon the attainment of certain

milestones in each contract. Revenues earned on contracts in process in excess
of billings are classified as unbilled contract costs and fees in the
accompanying balance sheet. There are no significant amounts included in the
accompanying balance sheet that are not expected to be recovered from existing
contracts at current contract values, or that are not expected to be collected
within one year, including amounts that are billed but not paid under retainage
provisions.
 
  Stock-based Compensation Plans
 
     The Company applies Accounting Principles Board Opinion ("APB") No. 25,
"Accounting for Stock Issued to Employees" and related interpretations in
accounting for its stock-based compensation plans (Note 2). Accordingly, no
accounting recognition is given to stock options granted at fair market value
until they are exercised. Upon exercise, net proceeds, including tax benefits
realized, are credited to equity.
 
  Income Taxes
 
     The Company, Thermo Instrument and Thermo Electron entered into a tax
allocation agreement under which the Company and Thermo Instrument are included
in Thermo Electron's consolidated federal and certain state income tax returns.
The agreement provides that in years in which the Company has taxable income, it
will pay to Thermo Electron amounts comparable to the taxes the Company would
have paid if it had filed separate tax returns. Upon completion of the proposed
initial public offering, Thermo Instrument's ownership of the Company will drop
below 80% and the Company will be required to file its own federal income tax
return.
 
     In accordance with Statement of Financial Accounting Standards ("SFAS")
No. 109, "Accounting for Income Taxes," the Company recognizes deferred income
taxes based on the expected future tax consequences of differences between the
financial statement basis and the tax basis of assets and liabilities,
calculated using enacted tax rates in effect for the year in which the
differences are expected to be reflected in the tax return.
 
  Earnings per Share
 
     Pursuant to certain Securities and Exchange Commission requirements,
earnings per share have been presented for all periods. Weighted average shares
for all periods represent the 5,000,000 shares issued to Thermo Instrument in
connection with the initial capitalization of the Company, and in 1996 the
effect of shares sold through a private placement, as well as the effect of the
assumed issuance of private placement shares and the assumed exercise of stock
options issued within one year prior to the Company's initial public offering in
all periods.
 
  Cash and Cash Equivalents
 
     Prior to its incorporation, the cash receipts and disbursements of the
Company's domestic operations were combined with other Thermo Instrument
corporate cash transactions and balances. Therefore, cash of the Company's
domestic operations through November 1996 is not included in the accompanying
balance sheet.
 
     As of December 28, 1996, $15,672,000 of the Company's cash equivalents were
invested in a repurchase agreement with Thermo Electron. Under this agreement,
the Company in effect lends excess cash to Thermo Electron, which Thermo
Electron collateralizes with investments principally consisting of U.S.
government agency securities, corporate notes, commercial paper, money market
funds and other marketable securities, in the amount of at least 103% of such
obligation. The Company's funds subject to the repurchase agreement are readily
convertible into cash by the Company and have an original maturity of three
months or less. The repurchase agreement earns a rate based on the 90-day
Commercial Paper Composite Rate plus 25 basis points, set at the beginning of
each quarter. Cash equivalents of $978,000 and $4,443,000 at year-end 1995 and
1996, respectively, at the Company's foreign operations were

  Other Assets
 
     Other assets in the accompanying balance sheet consists primarily of
acquired technology and the cost of acquired patents that are being amortized
using the straight-line method over their estimated useful lives, ranging from 5
to 20 years. Accumulated amortization was $705,000 and $925,000 at year-end 1995
and 1996, respectively.
 
  Cost in Excess of Net Assets of Acquired Companies
 
     The excess of cost over the fair value of net assets of acquired companies
is amortized using the straight-line method over 40 years. Accumulated
amortization was $1,196,000 and $1,627,000 at year-end 1995 and 1996,
respectively. The Company assesses the future useful life of this asset whenever
events or changes in circumstances indicate that the current useful life has
diminished. The Company considers the future undiscounted cash flows of the
acquired companies in assessing the recoverability of this asset. If impairment
has occurred, any excess of carrying value over fair value is recorded as a
loss.
 
  Foreign Currency
 
     All assets and liabilities of the Company's foreign subsidiaries are
translated at year-end exchange rates, and revenues and expenses are translated
at average exchange rates for the year, in accordance with SFAS No. 52, "Foreign
Currency Translation." Resulting translation adjustments are reflected as a
separate component of shareholders' investment titled "Cumulative translation
adjustment." Foreign

currency transaction gains and losses are included in the accompanying statement
of income and are not material for the three years presented.
 
  Fair Value of Financial Instruments
 
     The Company's financial instruments consist primarily of cash and cash
equivalents, accounts receivable, notes payable and current maturities of
long-term obligation, accounts payable, due to parent company and affiliated
companies and long-term obligation. The Company's long-term obligation bears
interest at a variable market rate and therefore, the carrying amount
approximates fair value (Note 6). The carrying amounts of the Company's
remaining financial instruments approximate fair value due to their short-term
nature.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities,
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Interim Financial Statements
 
     The financial statements as of June 28, 1997 and for the six-month periods
ended June 29, 1996 and June 28, 1997, are unaudited but, in the opinion of
management, reflect all adjustments of a normal recurring nature necessary for a
fair presentation of results for these interim periods. The results of
operations for the six-month period ended June 28, 1997 are not necessarily
indicative of the results to be expected for the entire year.
 
2.  EMPLOYEE BENEFIT PLANS
 
  Stock-based Compensation Plans
 
  Stock Option Plans
  ------------------  
     In November 1996, the Company adopted a stock-based compensation plan for
its key employees, directors, and others, which permits the grant of stock and
stock-based awards as determined by the human resources committee of the
Company's Board of Directors (the "Board Committee"), including restricted
stock, stock options, stock bonus shares or performance-based shares. The option
recipients and the terms of options granted under this plan are determined by
the Board Committee. Options granted become exercisable in September 1997, and
are subject to certain transfer restrictions and the right of the Company to
repurchase shares issued upon exercise of the options at the exercise price,
upon certain events. The restrictions and repurchase rights generally will be
deemed to have lapsed ratably over periods ranging from five to ten years after
the first anniversary of the grant date, depending on the term of the option,
which generally ranges from ten to twelve years. Nonqualified stock options may
be granted at any price determined by the Board Committee, although incentive
stock options must be granted at not less than the fair market value of the
Company's stock on the date of grant. As of March 31, 1997, no options had been
granted under this plan. In addition to the Company's stock-based compensation
plans, certain officers and key employees may also participate in the
stock-based compensation plans of Thermo Electron and Thermo Instrument.
 
  Employee Stock Purchase Program
  ------------------------------- 
     Substantially all of the Company's full-time U.S. employees are eligible to
participate in an employee stock purchase program sponsored by Thermo Instrument
and Thermo Electron. Under this program,

shares of Thermo Instrument's and Thermo Electron's common stock can be
purchased at the end of a 12-month period at 95% of the fair market value at the
beginning of the period, and the shares purchased are subject to a six-month
resale restriction. Prior to November 1, 1995, the applicable shares of common
stock could be purchased at 85% of the fair market value at the beginning of the
period, and the shares purchased were subject to a one-year resale restriction.
Shares are purchased through payroll deductions of up to 10% of each
participating employee's gross wages.
 
  401(k) Savings Plan
 
     Substantially all of the Company's full-time U.S. employees are eligible to
participate in Thermo Electron's 401(k) savings plan. Contributions to the
401(k) savings plan are made by both the employee and the Company. Company
contributions are based upon the level of employee contributions. The Company
contributed and charged to expense $175,000, $178,000, and $176,000 in fiscal
1994, 1995 and 1996, respectively.
 
  Defined Benefit Pension Plans
 
     The Company's German subsidiary has a defined benefit pension plan covering
substantially all of its full-time employees. Benefits are based on a percentage
of eligible earnings for each year of service in excess of ten.

     A provision has not been made for U.S. or additional foreign taxes on
$6.7 million of undistributed earnings of foreign subsidiaries that could be
subject to taxation if remitted to the U.S. because the Company currently plans
to keep these amounts permanently reinvested overseas. The Company believes that
any additional U.S. tax liability due upon remittance of such earnings would be
immaterial due to available U.S. foreign tax credits.
 
5.  RELATED PARTY TRANSACTIONS
 
  Corporate Services Agreement
 
     The Company and Thermo Electron have a corporate services agreement under
which Thermo Electron's corporate staff provides certain administrative
services, including certain legal advice and services, risk management, certain
employee benefit administration, tax advice and preparation of tax returns,
centralized cash management, and certain financial and other services, for which
the Company pays Thermo Electron annually an amount equal to 1.0% of the
Company's revenues. The Company paid an annual fee equal to 1.25% and 1.20% of
the Company's revenues in 1994 and 1995, respectively. The annual fee is
reviewed and adjusted annually by mutual agreement of the parties. For these
services, the Company was charged $483,000, $552,000 and $520,000 in 1994, 1995
and 1996, respectively. The corporate services agreement is renewed annually but
can be terminated upon 30 days' prior notice by the Company or upon the
Company's withdrawal from the Thermo Electron Corporate Charter (the Thermo
Electron Corporate Charter defines the relationships among Thermo Electron and
its majority-owned subsidiaries). Management believes that the service fee
charged by Thermo Electron is reasonable and that such fees are representative
of the expenses the Company would have incurred on a stand-alone basis. For
additional items such as employee benefit plans, insurance coverage, and other
identifiable costs, Thermo Electron charges the Company based upon costs
attributable to the Company.
 
  Repurchase Agreement
 
     The Company invests excess cash in a repurchase agreement with Thermo
Electron as discussed in Note 1.
 
  Due to parent company and affiliated companies
 
     The Company has borrowed funds from a wholly owned subsidiary of Thermo
Optek Corporation, a majority-owned subsidiary of Thermo Instrument, pursuant to
certain promissory notes. The Company had $1,388,000 and $1,928,000 outstanding
under the promissory notes at year-end 1995 and 1996, respectively. The notes
bear interest at a variable rate. The interest rate for the notes outstanding at
year-end 1995 and 1996 was 4.6% and 3.8%, respectively. The notes were repaid in
February 1997. In addition, the Company had $3,617,000 and $2,611,000 of
noninterest-bearing advances from Thermo Instrument and affiliated companies at
year-end 1995 and 1996, respectively, which are due on demand.
 
     In December 1996, the Company borrowed $2,778,000 pursuant to a
noninterest-bearing advance from a wholly owned subsidiary of Thermo Instrument,
which was repaid on January 15, 1997.

$368,000 in 1994, 1995 and 1996, respectively, as a reduction in selling,
general and administrative expenses in the accompanying statement of income.
 
6.  SHORT- AND LONG-TERM OBLIGATIONS
 
Short-term Obligations
 
     Notes payable and current maturities of long-term obligation in the
accompanying balance sheet includes $13,523,000 and $10,813,000 at year-end 1995

Company's foreign subsidiaries. The weighted average interest rate for these
borrowings at year-end 1995 and 1996 was 5.0% and 4.1%, respectively. Unused
lines of credit aggregated $7,794,000 at December 28, 1996. As of December 28,
1996, $1,400,000 of the total lines of credit are secured by property at the
Company's German subsidiary and the remainder is guaranteed by Thermo Electron.
 
Long-term Obligation
 
     In October 1994, the Company's German subsidiary borrowed 11,500,000 German
deutsche marks pursuant to a promissory note, payable in monthly installments of
99,200 German deutsche marks with a final payment in October 2004. The balance
outstanding was $7,297,000 and $5,988,000 at year-end 1995 and 1996,
respectively. The loan is secured by property at the Company's German subsidiary
with a net book value of $9,746,000 at year-end 1996. The note bears interest at
a variable rate, which was 4.7% and 3.75% at year-end 1995 and 1996,
respectively.
 
     The annual repayment requirements of the long-term obligation as of
December 28, 1996, are $765,000 in each year from 1997 through 2001 and

8.  CONCENTRATION OF RISK AND GEOGRAPHICAL INFORMATION
 
     Various components of the Company's products are supplied by sole-source
vendors. The Company has not experienced significant difficulty in obtaining
adequate supplies from these vendors, and has identified alternate suppliers.
However, there can be no assurance that the unanticipated loss of a single
vendor would not result in delays in shipments or in the introduction of new
products.
 
     The following table shows data for the Company by geographical area.

9.  SUBSEQUENT EVENTS
 
  Acquisition
 
     On December 31, 1996, the Company acquired the assets, subject to certain
liabilities, of the Autometrics division of Svedala Industries Inc.
("Autometrics"), for $1,347,000 in cash. Autometrics is a manufacturer and
marketer of on-line analysis instruments for the minerals processing industry.
 
     The acquisition has been accounted for using the purchase method of
accounting and its results of operations have been included in the accompanying
financial statements from its date of acquisition. The cost of the acquisition
exceeded the estimated fair value of the acquired net assets by $400,000, which
is being amortized over 40 years. Allocation of the purchase price was based on
an estimate of the fair value of the net assets acquired and is subject to
adjustment upon finalization of the purchase price allocation. To date no
information has been gathered that would cause the Company to believe that the
final allocation of the purchase price will be materially different than the
preliminary estimate.
 
     Based on unaudited data, the following table presents selected financial
information for the Company and Autometrics on a pro forma basis, assuming the
Companies had been combined since the beginning of 1996. Pro forma data is not
presented for the three months ended March 29, 1997 since the results of the
Company and Autometrics were combined for substantially the entire period.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The Delaware General Corporation Law and the Registrant's Certificate of
Incorporation and By-Laws limit the monetary liability of directors to the
Registrant and to its stockholders and provide for indemnification of the
Registrant's officers and directors for liabilities and expenses that they may
incur in such capacities. In general, officers and directors are indemnified
with respect to actions taken in good faith in a manner reasonably believed to
be in, or not opposed to, the best interests of the Registrant, and with respect
to any criminal action or proceeding, actions that the indemnitee had no
reasonable cause to believe were unlawful. The Registrant also has
indemnification agreements with its directors and officers that provide for the
maximum indemnification allowed by law. Reference is made to the Registrant's
Certificate of Incorporation, By-Laws and form of Indemnification Agreement for
Officers and Directors incorporated by reference as Exhibits 3.1, 3.2 and 10.12
hereto, respectively.
 
     Thermo Electron has an insurance policy which insures the directors and
officers of Thermo Electron and its subsidiaries, including the Registrant,
against certain liabilities which might be incurred in connection with the
performance of their duties.
 
     The Selling Shareholders are obligated under the Purchase Agreements to
indemnify Directors, officers and controlling persons of the Registrant against
certain liabilities, including liabilities under the Securities Act.
 
ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES
 
     On November 26, 1996, the Registrant issued 5,000,000 shares of Common
Stock (adjusted to reflect a one-for-two reverse stock split effected in May
1997) to Thermo Instrument System Inc. in exchange for the assets, liabilities
and business of its Gamma-Metrics subsidiary and Radiometrie division at the
time of the incorporation of the Registrant. Exemption from registration of this
transaction is claimed under Section 4(2) of the Securities Act.
 
     On December 16, 1996 the Registrant sold an aggregate of 833,333 shares of
Common Stock to accredited investors for an aggregate purchase price of
$12,500,000, pursuant to Regulation D of the Commission promulgated under the
Securities Act. On December 27, 1996, the Registrant sold an aggregate of
134,500 shares of Common Stock to accredited investors for an aggregate purchase
price of $2,017,500 pursuant to Regulation D of the Commission promulgated under
the Securities Act.

ITEM 16.  EXHIBITS AND FINANCIAL STATEMENT SCHEDULES
 
     (a) EXHIBITS
 
     See the Exhibit Index included immediately preceding the exhibits to this
Registration Statement.
 
     (b) FINANCIAL STATEMENT SCHEDULES
 
     Financial Statement Schedules as of December 28, 1996 and the Report of
Independent Accountants on such schedules are included in this Registration
Statement. All other schedules are omitted because they are not applicable or
are not required under Regulation S-X.
 
ITEM 17.  UNDERTAKINGS
 
     (a) The undersigned Registrant hereby undertakes:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:
 
             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;
 
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than 20 percent change in
        the maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement;
 
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement.
 
          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.
 
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
     (b) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions contained in the Certificate of
Incorporation and By-Laws of the Registrant and the laws of the State of
Delaware, or otherwise, the Registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the Registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Metrika Systems Corporation:
 
     We have audited, in accordance with generally accepted auditing standards,
the consolidated financial statements of Metrika Systems Corporation included in
Metrika Systems Corporation's Form S-1 and have issued our report thereon dated
March 31, 1997 (except with respect to certain matters discussed in Note 9, as
to which the date is June 24, 1997). Our audits were made for the purpose of
forming an opinion on the basic consolidated financial statements taken as a
whole. Metrika Systems Corporation's schedule of Valuation and Qualifying
Accounts, included in Schedule II on page S-2, is the responsibility of the
Company's management and is presented for purposes of complying with the
Securities and Exchange Commission's rules and is not part of the basic
consolidated financial statements. This schedule has been subjected to the
auditing procedures applied in the audits of the basic consolidated financial
statements and, in our opinion, fairly states, in all material respects, the
financial data required to be set forth therein in relation to the basic
consolidated financial statements taken as a whole.

Re:  Registration Statement on Form S-1 Relating to 967,828 Shares of
     the Common Stock, $.01 par value, of Metrika Systems Corporation
 
Dear Sirs:
 
     I am General Counsel to Metrika Systems Corporation, a Delaware corporation
(the "Company"), and have acted as counsel in connection with the registration
under the Securities Act of 1933, as amended, on Form S-1 (the "Registration
Statement"), of 967,828 shares of the Company's Common Stock, $.01 par value per
share (the "Shares"), which may from time to time be sold by certain
shareholders of the Company.
 
     I or a member of my staff have reviewed the corporate proceedings taken by
the Company with respect to the authorization of the issuance of the Shares. I
or a member of my staff have also examined and relied upon originals or copies,
certified or otherwise authenticated to my satisfaction, of all corporate
records, documents, agreements or other instruments of the Company, and have
made investigations of law and have discussed with the Company's representatives
questions of fact that I or a member of my staff have deemed necessary or
appropriate.
 
     Based upon and subject to the foregoing, I am of the opinion that the
Shares have been duly authorized by the Company and are validly issued, fully
paid and non-assessable.
 
     I hereby consent to the filing of this opinion as Exhibit 5 to the
Registration Statement, including any amendments thereto, and to the use of my
name under the caption "Legal Opinion" in the prospectus constituting a part
