EXHIBIT 10.11

                             EMPLOYMENT AGREEMENT

     This Agreement, effective as of the 3rd day of October, 2000 (the
"Effective Date"), is made by and between CiDRA Corporation, a Delaware
Corporation ("CiDRA"), and Alan D. Kersey (EMPLOYEE).

     WHEREAS, CiDRA desires to engage the services of EMPLOYEE;

     WHEREAS, EMPLOYEE is willing to provide such services to CIDRA;

     WHEREAS EMPLOYEE and CiDRA have entered into an Intellectual Property
Agreement dated as of the date hereof, which includes among other things, a
covenant not to compete with CiDRA by the EMPLOYEE, a non-solicitation agreement
and an assignment of inventions agreement; and

     NOW, THEREFORE, the parties hereto agree as follows:

1.   EMPLOYMENT TERM

     EMPLOYEE will serve as Vice President, Chief Technology Officer of CiDRA.
Subject to the provisions of Sections 3 and 4 below, the Initial Term of this
Agreement shall be for a period of two (2) years, beginning with the Effective
Date.  EMPLOYEE's employment and this Agreement shall automatically extend for
additional one (1) year periods (each such extension a "Subsequent Term") unless
either party to this Agreement notifies the other in writing at least 90 days
prior to the end of the Initial Term or any Subsequent Term that he or it does
not want to extend the employment.  The Initial Term and the Subsequent Term are
referred to in this Agreement collectively as the "Term".

2.   COMPENSATION

     a.   So long as EMPLOYEE continues to perform the services specified in
          Section 1 and this Agreement has not terminated, EMPLOYEE shall
          receive a salary at the annual rate of One Hundred Eighty Five
          Thousand Dollars ($185,000.00) (the "Annual Compensation"), payable in
          accordance with CiDRA's standard payroll practices and procedures.

     b.   So long as EMPLOYEE continues to perform the services specified in
          Section 1 and this Agreement has not terminated, EMPLOYEE shall be
          eligible for bonus compensation equal to 30% of the Annual
          Compensation. The bonus compensation will be paid upon achievement of
          performance milestones as specified by CiDRA's Compensation Committee.

     c.   CiDRA shall reimburse EMPLOYEE for his reasonable expenses incurred in
          performing his duties to CiDRA hereunder, subject to policies
          established by the Board of Directors of CiDRA (the "Board") from time
          to time.


     d.   EMPLOYEE shall receive such other benefits as CiDRA provides to its
          similarly situated executive employees.

     e.   EMPLOYEE shall receive three (3) weeks vacation (15 days) during each
          calendar year. Vacation shall accrue at the rate of 1.25 days per
          month. Accrued but unused vacation shall be carried over to the next
          calendar year.

     f.   CiDRA will provide group health medical insurance coverage for
          EMPLOYEE and his eligible dependents through a plan maintained by
          CiDRA for its employees. CiDRA shall have the right to adopt a medical
          insurance plan that requires some level of copayment from employees,
          including EMPLOYEE.


3.   TERMINATION OF EMPLOYMENT.

     In the event of the EMPLOYEE'S termination for any reason, CiDRA shall pay
to the EMPLOYEE on his termination date all amounts of Annual Compensation due
and owing, reimbursements properly submitted for expenses incurred prior to the
termination date and any accrued but unused vacation owed to the EMPLOYEE as of
the termination date (the "Accrued Obligations").  In addition, CiDRA shall pay
to the EMPLOYEE the following:

     a.   If CiDRA terminates EMPLOYEE's employment for Cause (as defined
          below), or EMPLOYEE's employment terminates due to his death or
          Disability (as defined below), or EMPLOYEE terminates his employment
          with CiDRA other than as a result of a Good Reason (as defined below)
          (but not in any event as a result of non-renewal of this Agreement in
          accordance with Section 1):

          i)  CiDRA shall compensate EMPLOYEE with severance pay equal to three
              (3) months Annual Compensation then in effect, without
              consideration for any Bonus Compensation, to be paid in equal
              installments over a three (3) month period following such
              termination; and

          ii) As of the Termination Date, EMPLOYEE shall not continue to
              participate in any benefit plans of CiDRA.

     b.   In the event that EMPLOYEE's employment is terminated by CiDRA without
          Cause, or by EMPLOYEE for Good Reason (but not in any event as a
          result of non-renewal of this Agreement in accordance with Section 1),
          CiDRA will provide EMPLOYEE with the following:

          i)  Severance pay equal to twelve (12) months Annual Compensation then
              in effect to be paid in equal installments (minus applicable
              withholdings) over a six (6) month period following such
              termination; and

                                      -2-


          ii) As of the Termination Date, EMPLOYEE shall not continue to
              participate in any benefit plans of CiDRA.

     Thereafter, no further amounts shall be due to EMPLOYEE.  CiDRA  may
request that EMPLOYEE sign a general release of all claims with CiDRA as a
condition for receiving any of the payments described in Section 3a. or 3b.


4.   TERMINATION OF EMPLOYMENT SUBSEQUENT TO A CHANGE OF CONTROL (as defined
     below)


     a.   Notwithstanding the provisions of Section 3b. above, if EMPLOYEE
          terminates his employment with Good Reason (but not in any event as a
          result of non-renewal of this Agreement in accordance with Section 1)
          within 24 months of a Change of Control (as defined below), EMPLOYEE
          will receive on his termination date the Accrued Obligations and
          severance pay equal to six (6) months Annual Compensation then in
          effect to be paid in equal installments (minus applicable
          withholdings) over a six (6) month period following such termination,
          and

     b.   All unvested stock options and/or restricted shares shall immediately
          vest.

     c.   In the event of a termination for Good Reason within 24 months of a
          Change of Control, the foregoing shall be EMPLOYEE's sole and
          exclusive remedy, Section 3b. shall be inoperative during such 24
          month period and EMPLOYEE shall not be entitled to any other or
          further payments, compensation or benefits from CiDRA. CiDRA may
          request that EMPLOYEE sign a general release of all claims with CiDRA
          as a condition for receiving any of the payments or benefits described
          in this Section 4.

     d.   For purposes of this Agreement:

          i)  "Cause" shall mean any act of or omission by EMPLOYEE in the
              conduct of EMPLOYEE's duties and responsibilities which
              constitutes gross negligence or willful misconduct, or any act of
              or omission by EMPLOYEE which involves dishonesty or criminal
              conduct. In the event the Board determines it has reason to
              terminate EMPLOYEE's employment for Cause, it shall give written
              notice to EMPLOYEE stating the specific grounds constituting
              Cause. In the event that the Cause alleged constitutes any act or
              omission in the conduct of EMPLOYEE's duties and responsibilities
              which constitutes gross negligence or willful misconduct, EMPLOYEE
              shall have an opportunity within five (5) days after receiving
              such notice to meet with the Board to discuss such allegations of
              Cause.

                                      -3-


          ii)  "Change of Control" shall mean: (i) any sale, lease, exchange or
               other transfer (in one transaction or a series of transactions)
               of all or substantially all of the assets of CiDRA; (ii)
               individuals who, as of the date hereof, constitute the entire
               Board of Directors of CiDRA (the "Incumbent Directors") cease for
               any reason to constitute at least a majority of the Board of
               Directors, provided that any individual becoming a director
               subsequent to the date hereof whose election was approved by a
               vote of at least a majority of the then Incumbent Directors shall
               be, for the purposes of this provision, considered as though such
               individual were an Incumbent Director; (iii) any consolidation or
               merger of CiDRA with any other entity where the stockholders of
               CiDRA immediately prior to the consolidation or merger, would
               not, immediately after the consolidation or merger, beneficially
               own, directly or indirectly, shares representing fifty percent
               (50%) of the combined voting power of all of the outstanding
               securities of the entity issuing cash or securities in the
               consolidation or merger (or its ultimate parent corporation, if
               any); (iv) a third person, including a "person" as defined in
               Section 13(d)(3) of the Exchange Act, becomes the beneficial
               owner (as defined in Rule 13d-3 under the Exchange Act) directly
               or indirectly, of securities of CiDRA representing seventy-five
               percent (75%) or more of the total number of votes that may be
               cast for the election of the directors of CiDRA; or (vi) the
               Board of Directors of CiDRA , by vote of a majority of all the
               Directors, adopts a resolution to the effect that a "Change-in-
               Control" has occurred for purposes of the Plan. The completion of
               an initial public offering of CiDRA's securities shall not, under
               any circumstances, constitute a Change of Control.

          iii) "Disability" shall mean EMPLOYEE's incapacity due to physical or
               mental illness as certified in writing by a physician selected by
               EMPLOYEE and reasonably acceptable to CiDRA (it being understood
               that (i) such physician shall be deemed to be reasonably
               acceptable to CiDRA if, within a period of fifteen (15) days
               after EMPLOYEE notifies CiDRA of the name of such physician,
               CiDRA does not object to the use of such physician, and (ii) if
               EMPLOYEE fails to select a physician within fifteen (15) days
               after a written request from CiDRA to do so, CiDRA shall have the
               right to select the physician to examine EMPLOYEE).

          iv)  "Good Reason" means that (i) EMPLOYEE's compensation has been
               materially reduced (and such reduction is not part of an overall
               reduction in compensation affecting other employees of CiDRA),
               (ii) EMPLOYEE's position, duties or responsibilities have been
               materially reduced, (iii) the EMPLOYEE's primary place of
               employment is moved to a location greater than sixty (60) miles
               away from its then current location, or (iv) CiDRA has not paid
               to EMPLOYEE when due any undisputed compensation, including
               salary or bonus, and in all such cases

                                      -4-


               (i-iv) the condition continues beyond 15 business days from the
               date CiDRA's Board is notified in writing of its existence.
               Notwithstanding anything contained herein to the contrary, a
               material reduction in EMPLOYEE's position, duties or
               responsibilities shall not be deemed to have occurred solely
               because of a Change of Control, such that, for example and
               without in anyway limiting the foregoing, a Change of Control
               which results in CiDRA becoming a subsidiary of another entity
               but does not reduce the responsibilities identified in Section 1
               that the EMPLOYEE performs for CiDRA shall not alone be deemed a
               material reduction of EMPLOYEE's position, duties or
               responsibilities.


5.   GOVERNING LAW; ARBITRATION; INJUNCTIVE AND OTHER RELIEF

     This Agreement shall be governed by and construed and enforced in
accordance with the laws of the State of Connecticut applicable to agreements

Arbitration Rules, and judgment on the award rendered by the arbitrators may be
entered in any court having jurisdiction thereof.

     Each of the parties to this Agreement acknowledges that a breach of this
Agreement may cause the other party irreparable harm which may not be adequately
compensated by money damages.  Therefore, in the event of a breach or threatened
breach by a party, injunctive or other equitable relief will be available to the
other party, and any arbitrator acting pursuant to this Agreement shall have the
authority to provide such injunctive or other equitable relief.  Remedies
provided herein are not exclusive, except as provided in Section 3.b.

     The arbitrator shall have the authority to award such remedies or relief
that a court of the State of Connecticut could order or grant in an action
governed by Connecticut law, including, without limitation, specific performance
of any obligation created under this Agreement, the issuance of an injunction,
or the imposition of sanctions for abuse or frustration of the arbitration
process.  The arbitration proceedings shall be conducted in Hartford,
Connecticut.

     Notwithstanding the foregoing, any party may bring and pursue an action in
any federal or state court located in Hartford, Connecticut seeking provisional
relief, including a temporary restraining order or preliminary injunction,
pending an arbitration proceeding.  Any provisional relief obtained shall be
discontinued once the arbitrator has assumed jurisdiction and ordered such
discontinuance.
