For Immediate Release

               ZYGO TO DISPOSE OF ITS ZYGO TERAOPTIX BUSINESS UNIT

Middlefield, Connecticut -- September 27, 2002 -- Zygo Corporation (NASDAQ:
ZIGO) announces that it will dispose of its Zygo TeraOptix business unit and
facility located in Westborough, Massachusetts. ZYGO is seeking a buyer for this
business. ZYGO will discontinue its telecommunications business in Westborough,
Massachusetts, no later than November 30, 2002. The disposition of this business
unit effectively terminates the Company's venture into the telecommunications
business. The Zygo TeraOptix operation had sales for the year ended June 30,
2002 of $4,158,000, or 5%, of ZYGO's consolidated sales.

With the dramatic changes in the telecommunications industry, including excess
capacity, capital spending cutbacks, and delays in deployment of high-speed
technologies, demand for the components produced by Zygo TeraOptix has
significantly decreased. Disposition of the Zygo TeraOptix business unit allows
ZYGO to concentrate on growth and profitability in its other two markets,
semiconductor and industrial.

The Company will record an impairment charge in accordance with SFAS 144 and
other related exit costs for the quarter ended September 27, 2002. The amount of
the charges, which have not yet been determined, will relate primarily to the
difference between the net book value of the applicable fixed assets
($28,000,000) and the estimated proceeds from the disposition of these assets.

Zygo Corporation (NASDAQ:ZIGO), headquartered in Middlefield, Connecticut, is a
worldwide developer and supplier of high-performance metrology instruments, high
precision optics, optical assemblies, and automation for the semiconductor and
industrial markets. See ZYGO's web site at www.zygo.com for additional
information.
