     This Amendment No. 1 to Schedule 13D (this "Amendment No. 1") amends and
supplements the Schedule 13D (the "Original 13D") filed with the Securities and
Exchange Commission on February 6, 1998 on behalf of John F. Blais, Jr. (the
"Reporting Person"). The disclosure set forth in this Amendment No. 1 is
qualified in its entirety by reference to the Merger Agreement (as defined
below) attached as Exhibit E to this Amendment No. 1 and to the Stockholder
Agreement (as defined below) attached as Exhibit F to this Amendment No. 1.

ITEM 1. SECURITY AND ISSUER.

The class of security to which this statement relates is the common stock, par
value $.01 per share ("Common Stock"), of NetOptix Corporation, a Delaware
corporation (the "Issuer"), formerly known as Galileo Corporation. The name and
address of the principal executive office of the Issuer is NetOptix Corporation,
Sturbridge Business Park, P.O. Box 550, Sturbridge, Massachusetts 01566.

ITEM 2. IDENTITY AND BACKGROUND.

(b)  The residence of the Reporting Person is 362 Singletary Lane, Framingham,
     MA 01701.

(c)  The Reporting Person is retired and no longer is employed.

ITEM 4. PURPOSE OF TRANSACTION.

        Pursuant to an Agreement and Plan of Merger (the "Merger Agreement")
among Corning Incorporated ("Corning"), CI Subsidiary, Inc. (the "Merger Sub")
and the Issuer (together with Corning and the Merger Sub, the "Merger
Partners") dated as of February 13, 2000, Andlinger Capital, Mr. Andlinger, Mr.
Magida, in his capacity as manager of Andlinger Capital and as Trustee of the
Trust, and the Reporting Person (each a "Stockholder") entered into a
Stockholder Voting Agreement and Irrevocable Proxy (the "Stockholder
Agreement") with the Merger Partners dated as of February 13, 2000. The
Reporting Person has entered into the Stockholder Agreement, and has agreed to
vote his shares in favor of the Merger Agreement, with the purpose of
supporting the merger of the Issuer with Corning.

      The Merger Agreement provides that the Merger Sub will merge with and into
the Issuer with the Issuer as the surviving entity (the "Merger"). Consummation
of the Merger is subject to the approval of the stockholders of the Issuer at a
special meeting to be called for such purpose (the "Special Stockholders
Meeting") and the satisfaction of certain other conditions set forth in the
Merger Agreement.

        As an inducement and an essential condition to Corning and the Merger
Sub entering into the Merger Agreement, pursuant to the Stockholder Agreement,
(a) the Stockholders agreed to vote their shares of the Issuer in favor of the
Merger and to the imposition of certain other restrictions on the exercise of
their voting power over their holdings of shares of capital stock of the
Issuer, and (b) the Stockholders and their respective Affiliates (as used in
the Stockholder Agreement) agreed to the imposition of certain restrictions on
the disposition of such shares, both as more fully described in Item 6 below.

        The Reporting Person does not have any plans or proposals with respect
to shares of the Issuer other than those described in this Amendment No. 1, or
which would be a consequence of the Merger, which relate to or would result in
any of the actions or transactions specified in clauses (a) through (j) of Item
4 of Schedule 13D.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

        As more fully described in Item 6 below, the Reporting Person, pursuant
to the terms of the Stockholder Agreement, has irrevocably granted a proxy with
respect to, and thus agreed to share his voting power over, the 806,652 shares
of Common Stock (the "Shares") which he beneficially owns with Corning and any
person designated by Corning to act in its place. In addition, by virtue of the
restrictions

   4

upon Transfer (as defined in the Stockholder Agreement) imposed upon each
Stockholder and his or its Affiliates, pursuant to the Stockholder Agreement,
the Reporting Person agreed not to exercise his dispositive power with respect
to the Shares until the conditions set forth in the Stockholder Agreement have
been satisfied.

ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO
        SECURITIES OF THE ISSUER.

     Pursuant to the terms of the Stockholder Agreement, the Reporting Person
agreed with Corning and the Merger Sub that he will vote his Shares, among other
things, (a) in favor of the Merger Agreement and the transactions contemplated
thereby; (b) against any action or agreement that would result in a breach in
any respect of any representation, warranty, agreement or covenant or any other
obligation or agreement of the Issuer under the Merger Agreement or in
connection with the Transactions and against any other Acquisition Proposal or
any Other Acquisition (each capitalized term as defined in the Stockholder
Agreement); and (c) against any other action which is intended, or could
reasonably be expected, to impede, interfere with, delay, postpone or materially
adversely affect the Merger or any other transaction contemplated by the Merger
Agreement (including the agreements referred to in the Merger Agreement), or any
of the transactions contemplated by the Stockholder Agreement.

     The Stockholder Agreement provided that each Stockholder irrevocably and
severally granted to Corning and any person designated by Corning to act in its
place a proxy, and appointed Corning and its designee as attorney-in-fact, with
full power of substitution and resubstitution, for and in the name, place and
stead of such Stockholder, to vote such Stockholder's shares of the Issuer, or
grant a consent or approval in respect of such shares, in a manner consistent
with the voting agreement set forth in the Stockholder Agreement. Accordingly,
pursuant to the Stockholder Agreement, the Reporting Person granted an
irrevocable proxy to vote the Shares to Corning and any person designated by
Corning to act in its place.

     In addition, the Stockholder Agreement provided that each Stockholder and
any of his or its Affiliates agreed not to (a) Transfer any or all of his or its
shares of the Issuer; (b) enter into any contract, option, commitment or other
arrangement (including any profit sharing arrangement) with respect to the
Transfer of such shares; or (c) enter into any other voting arrangement, whether
by proxy, voting agreement, voting trust, power-of-attorney or other grant with
respect to the shares of the Issuer. Under the terms of the Stockholder
Agreement, such restrictions upon Transfer of the shares of the Issuer expire
upon the completion of the Special Stockholders Meeting. Accordingly, pursuant
to the Stockholder Agreement, the Reporting person agreed not to exercise his
right to dispose or direct the disposition of the Shares during the term of the
Stockholder Agreement.

     By its terms, the Stockholder Agreement will terminate immediately upon the
earlier of (i) the termination of the Merger Agreement by mutual agreement of
the Issuer and Corning or, in accordance with the terms of the Merger Agreement,
by the Issuer as a result of breaches or non-performance by Corning, (ii) the
effective time of the Merger or (iii) the first anniversary of the date of the
Stockholder Agreement.
