                                 PROXY STATEMENT


     This Proxy Statement is furnished in connection with the solicitation of
proxies by the Board of Directors of Cognex Corporation (the Corporation") for
use at the Special Meeting of Stockholders in Lieu of the 2001 Annual Meeting to
be held on Thursday, April 26, 2001, at the time and place set forth in the
notice of the meeting, and at any adjournments thereof. The approximate date on
which this Proxy Statement and form of proxy are first being sent to
stockholders is March 23, 2001.

     If the enclosed proxy is properly executed and returned, it will be voted
in the manner directed by the stockholder. If no instructions are specified with
respect to any particular matter to be acted upon, proxies will be voted in
favor thereof. Any person giving the enclosed form of proxy has the power to
revoke it by voting in person at the meeting, or by giving written notice of
revocation to the Clerk of the Corporation at any time before the proxy is
exercised.

     The holders of a majority in interest of all Common Stock issued,
outstanding and entitled to vote are required to be present in person or be
represented by proxy at the meeting in order to constitute a quorum for
transaction of business. The election of a nominee for Director will be decided
by plurality vote. Both abstentions and broker non-votes" are counted as present
for the purposes of determining the existence of a quorum for the transaction of
business. However, for purposes of determining the number of shares voting on a
particular proposal, abstentions and broker non-votes" are not counted as votes
cast or shares voting.

     The Corporation will bear the cost of the solicitation. It is expected that
the solicitation will be made primarily by mail, but regular employees or
representatives of the Corporation (none of whom will receive any extra
compensation for their activities) may also solicit proxies by telephone,
telegraph and in person and arrange for brokerage houses and other custodians,
nominees and fiduciaries to send proxies and proxy materials to their principals
at the expense of the Corporation.

entitled to notice of and to vote at the meeting. On that date the Corporation
had outstanding and entitled to vote 43,477,675 shares of Common Stock, par
value $.002 per share. Each outstanding share of the Corporation's Common Stock
entitles the record holder to one vote.

                              ELECTION OF DIRECTORS

     Pursuant to Massachusetts law, the Board of Directors is divided into three
classes, with each class as nearly equal in number as possible. One class is
elected each year for a term of three years. It is proposed that Robert J.
Shillman and Anthony Sun, whose terms expire at this meeting, be elected to
serve terms of three years and that Patrick Alias be elected to serve a term of
one year, and in each case until their successors are duly elected and qualified
or until they sooner die, resign or are removed. The Board of Directors is being
expanded from five to six members.




     The persons named in the accompanying proxy will vote, unless authority is
withheld, to expand the Board of Directors to six members and to elect the
nominees named below. If such nominees should become unavailable for election,
which is not anticipated, the persons named in the accompanying proxy will vote
for such substitutes as the Board of Directors may recommend. Should management
not recommend a substitute for any nominee, the proxy will be voted for the
election of the remaining nominees. The nominees are not related to the other or
to any Executive Officer of the Corporation or its subsidiaries.

                   COMPENSATION/STOCK OPTION COMMITTEE REPORT
                            ON EXECUTIVE COMPENSATION

     The Corporation's executive compensation program is administered by the
Compensation/Stock Option Committee (the Committee"), which determines executive
officer compensation annually. The Committee is composed of independent
directors who are not employees of the Corporation and its determinations with
respect to compensation for a fiscal year are made at the beginning of the
fiscal year.

     In its deliberations, the Committee considers (i) the levels of
responsibility associated with each executive's position, (ii) the past
performance of the individual executive, (iii) the extent to which any
individual, departmental or Corporation-wide goals have been met, (iv) the
overall competitive environment and the level of compensation necessary to
attract and retain talented and motivated individuals in key positions, and (v)
the recommendations of appropriate officers of the Corporation.

     The Corporation's compensation program utilizes a combination of base
salaries, annual bonuses and stock option awards.


                                       4



     In determining the base salaries paid to the Corporation's executive
officers for the year ended December 31, 2000, the Committee considered, in
particular, their levels of responsibility, salary increases awarded in the
past, and the executive's experience and potential.

     The Committee views annual bonuses as a vehicle for rewarding executives
for meeting performance objectives. The Committee establishes individual and
corporate performance targets each year. Executive officers are eligible to
receive annual cash bonuses upon achievement of such pre-determined performance
targets. The annual bonuses for the fiscal year ended December 31, 2000 reflect
the achievement of predetermined targets related to the Corporation's operating
income, other company metrics and individual goals.

     The Corporation's stock option program is intended to reward the
participating executives for their efforts in building shareholder value and
improving corporate performance over the long term. The stock option program
also promotes the retention of talented executives. In determining the number of
options granted to executive officers, the Committee takes into consideration
options granted to such executives in previous years and the potential value
which may be realized upon exercise of the options as a result of appreciation
of the Corporation's stock during the option term.

     The Internal Revenue Code limits the deduction a public company is
permitted for compensation paid to the chief executive officer and to the four
most highly compensated executive officers, other than the chief executive
officer. Generally, amounts paid in excess of $1 million to a covered executive,
other than performance-based compensation, cannot be deducted. In order to
qualify as performance-based compensation under the tax law, certain
requirements must be met, including approval of the performance measures by the
stockholders. In its deliberations, the Committee considers ways to maximize
deductibility of executive compensation, while retaining the discretion the
Committee considers appropriate to compensate executive officers at levels
commensurate with their responsibilities and achievements.


                 COMPENSATION OF ROBERT J. SHILLMAN, PRESIDENT,
                      CHIEF EXECUTIVE OFFICER AND CHAIRMAN

     The Committee established the compensation of Robert J. Shillman, the
President, Chief Executive Officer and Chairman of the Board of Directors of the
Corporation for the fiscal year ended December 31, 2000, using the same criteria
that were used to determine the compensation of other executive officers as
described above. In establishing Mr. Shillman's compensation for the fiscal year
ended December 31, 2000, the Committee considered his level of responsibility,
salary increases awarded in the past, and the significant role that Mr. Shillman
has played in setting the strategic direction of the Corporation. Mr. Shillman's
base compensation was increased approximately 2.9% in general recognition of his
level of responsibility and his individual efforts for the benefit of the
Corporation. Mr. Shillman's annual bonus of $558,000, for the fiscal year ended
December 31, 2000, was based upon the achievement by the Corporation of
pre-determined targets with respect to operating income and is intended to
reward Mr. Shillman for his role in the achievement of that objective. Mr.
Shillman was also granted options for the purchase of 60,000 shares at $18.125
per share. It should be noted that the Corporation's operating income for the
year ended December 31, 2000 increased 152% over operating income for the year
ended December 31, 1999.

     The foregoing report has been approved by all members of the Committee.

desires and to respond to appropriate questions. The engagement of
PricewaterhouseCoopers LLP was approved by the Board of Directors at the

     The Audit Committee has reviewed and discussed the Corporation's audited

matters required to be discussed by Statement of Auditing Standards No. 61,

to the conduct of the audit of the Corporation's financial statements are to be

     The Audit Committee acts pursuant to the Audit Committee Charter, a copy of
which is attached as Appendix A" to this Proxy Statement. Each of the members of
the Audit Committee qualifies as an independent" Director under the current

     Based on the review and discussions referred to above, the Audit Committee
recommended to the Corporation's Board of Directors that the Corporation's
audited financial statements be included in the Corporation's Annual Report on
Form 10-K for the fiscal year ended December 31, 2000.

                                 AUDIT COMMITTEE

                                 Reuben Wasserman


(1) THE MATERIAL IN THIS REPORT, INCLUDING THE AUDIT COMMITTEE CHARTER, IS NOT
    SOLICITING MATERIAL," IS NOT DEEMED FILED WITH THE COMMISSION AND IS NOT TO
    BE INCORPORATED BY REFERENCE IN ANY FILING OF THE COMPANY UNDER THE
    SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES EXCHANGE ACT OF 1934,
    AS AMENDED, WHETHER MADE BEFORE OR AFTER THE DATE HEREOF AND IRRESPECTIVE OF
    ANY GENERAL INCORPORATION LANGUAGE IN ANY SUCH FILING.


                                       10


            COMPLIANCE WITH SECTION 16(A) OF THE SECURITIES EXCHANGE
                                   ACT OF 1934

     Section 16(a) of the Securities Exchange Act of 1934 requires the
Corporation's officers and Directors and persons owning more than 10% of the
outstanding Common Stock of the Corporation to file reports of ownership and
changes in ownership with the Commission. Officers, Directors and greater than
10% holders of Common Stock are required by the Commission's regulation to
furnish the Corporation with copies of all Section 16(a) forms they file.

     Based solely on copies of such forms furnished as provided above, the
Corporation believes that during the year ended December 31, 2000, all Section
16(a) filing requirements applicable to its Officers, Directors and owners of
greater than 10% of its Common Stock were complied with.


                           DEADLINES FOR SUBMISSION OF
                              STOCKHOLDER PROPOSALS

     Under regulations adopted by the Commission, any proposal submitted for
inclusion in the Corporation's Proxy Statement relating to the Annual Meeting of
Stockholders to be held in 2002 must be received at the Corporation's principal
executive offices in Natick, Massachusetts on or before November 23, 2001.
Receipt by the Corporation of any such proposal from a qualified stockholder in
a timely manner will not ensure its inclusion in the proxy material because
there are other requirements in the proxy rules for such inclusion.

     In accordance with the provisions of Rule 14a-4(c) promulgated under the
Securities Exchange Act of 1934, if the Corporation does not receive notice of a
shareholder proposal to be raised at its 2002 Annual Meeting on or before
February 6, 2002, then in such event, the management proxies shall be allowed to
use their discretionary voting authority when the proposal is raised at the 2002
Annual Meeting.

     In addition to the Commission requirements regarding stockholder proposals,
the Corporation's By-Laws contain provisions regarding matters to be brought
before stockholder meetings. If stockholder proposals, including proposals
regarding the election of Directors, are to be considered at the 2002 Annual
Meeting, notice of them whether or not they are included in the Corporation's
proxy statement and form of proxy, must be given by personal delivery or by
United States mail, postage prepaid, to the Clerk of the Corporation on or
before February 8, 2002.


                                  OTHER MATTERS

     Management knows of no matters which may properly be and are likely to be
brought before the meeting other than the matters discussed herein. However, if
any other matters properly come before the meeting, the persons named in the
enclosed proxy will vote in accordance with their best judgment.


     The cost of this solicitation will be borne by the Corporation. It is
expected that the solicitation will be made primarily by mail, but regular
employees or representatives of the Corporation (none of whom will receive any
extra compensation for their activities) may also solicit proxies by telephone,
telegraph and in person and arrange for brokerage houses and other custodians,

                    AUDIT COMMITTEE OF THE BOARD OF DIRECTORS
                                     CHARTER

I.       PURPOSE

         The primary function of the Audit Committee is to assist the Board of
         Directors in fulfilling its oversight responsibilities by reviewing:
         the financial reports and other financial information provided by the
         Corporation to any governmental body or the public; the Corporation's
         systems of internal controls regarding finance, accounting, legal
         compliance and ethics that management and the Board have established;
         and the Corporation's auditing, accounting and financial reporting
         processes generally. Consistent with this function, the Audit Committee
         encourages continuous improvement of, and adherence to, the
         Corporation's policies, procedures and practices at all levels. The
         Audit Committee's primary duties and responsibilities are to:

               o  Serve as an independent and objective party to monitor the
                  Corporation's financial reporting process and internal control
                  system.

               o  Review and appraise the audit efforts of the Corporation's
                  independent accountants.

               o  Provide an open avenue of communication among the independent
                  accountants, financial and senior management, and the Board of
                  Directors.

         The Audit Committee will primarily fulfill these responsibilities by
         carrying out the activities enumerated in Section IV of this Charter.

II.      COMPOSITION

         The Audit Committee shall be comprised of three or more directors as
         determined by the Board, each of whom shall be independent directors,
         and free from any relationship that, in the opinion of the Board, would
         interfere with the exercise of his or her independent judgment as a
         member of the Committee. All members of the Committee shall have a
         working familiarity with basic finance and accounting practices, and at
         least one member of the Committee shall have accounting or related
         financial management expertise.

         The members of the Committee shall be elected by the Board at the
         annual organizational meeting of the Board or until their successors
         shall be duly elected and qualified. Unless a Chair is elected by the
         full Board, the members of the Committee may designate a Chair by
         majority vote of the full Committee membership.


                                       A-1



III.     MEETINGS

         The Committee shall:

              o   Meet with the independent accountants and senior financial
                  management at least twice annually: once to review and agree
                  upon the scope of work to be performed in the upcoming audit
                  and once to review the results of the completed audit.

              o   Communicate each quarter with the independent accountants and
                  senior financial management (via telephone conference if
                  appropriate) to review the results of the accountants' limited
                  review procedures of the quarterly results of operations prior
                  to the public release of said information.

              o   Meet at any time as circumstances dictate.

         DOCUMENTS/REPORT REVIEW

              1.  Review and update this Charter periodically, at least
                  annually, as conditions dictate.

              2.  Review the organization's annual financial statements and any
                  reports or other financial information submitted to any
                  governmental body, or the public, including any certification,
                  report, opinion, or review rendered by the independent
                  accountants.

             3.   Review with financial management and the independent
                  accountants the Corporation's quarterly results prior to the
                  release of earnings. The Chair of the Committee may represent
                  the entire Committee for purposes of this review.

         INDEPENDENT ACCOUNTANTS

             4.   Recommend to the Board of Directors the selection of the
                  independent accountants, considering independence and
                  effectiveness and approve the fees and other compensation to
                  be paid to the independent accountants. On an annual basis,
                  the Committee should review and discuss with the accountants
                  all significant relationships the accountants have with the
                  Corporation to determine the accountants' independence.

            5.    Review the performance of the independent accountants with the
                  Corporation's senior financial management and approve any
                  proposed discharge of the independent accountants when
                  circumstances warrant.

            6.    Meet with the independent auditors and financial management of
                  the Corporation to review the scope of the proposed audit for
                  the current year and the audit procedures to be utilized, and
                  at the conclusion thereof review such audit, including any
                  comments or recommendations of the independent auditors,
                  including any serious difficulties or disputes with management
                  encountered during the course of the audit.

                                      A-2



            7.    Review with the independent auditors and senior financial
                  personnel the adequacy and effectiveness of the accounting and
                  financial controls of the Corporation, and elicit any
                  recommendations for the improvement of such internal control
                  procedures or particular areas where new or more detailed
                  controls or procedures are desirable. Particular emphasis
                  should be given to the adequacy of such internal controls to
                  expose any payments, transactions, or procedures that might be
                  deemed illegal or otherwise improper.

         FINANCIAL REPORTING PROCESSES

            8.    In consultation with the independent accountants, review the
                  integrity of the organization's financial reporting processes,
                  both internal and external.

            9.    Consider the independent accountants' judgments about the
                  quality and appropriateness of the Corporation's accounting
                  principles as applied in its financial reporting.

         OTHER

            10.   Meet with the independent accountants and management in
                  separate executive sessions to discuss any matters that the
                  Committee or these groups believe should be discussed
                  privately with the Audit Committee.

            11.   Report Committee actions to the Board of Directors with such
                  recommendations as the Committee may deem appropriate.

            12.   Prepare a letter for inclusion in the annual report that
                  describes the Committee's composition and responsibilities,
                  and how they were discharged.

            13.   The Audit Committee shall have the power to conduct or
                  authorize investigations into any matters within the
                  Committee's scope of responsibilities. The Committee shall be
                  empowered to retain independent counsel, accountants, or
                  others to assist it in the conduct of any investigation.

            14.   The Committee will perform such other functions as assigned by
                  law, the Corporation's charter or bylaws, or the Board of
                  Directors.

            15.   Provide an independent, direct communication link between the
                  Board of Directors and the independent accountants.
