ZYGO RECORDS SOLID IMPROVEMENTS IN Q1 ORDERS, REVENUES, AND EARNINGS OVER PRIOR YEAR

MIDDLEFIELD, CT, OCTOBER 27, 2005 – Zygo Corporation (NASDAQ: ZIGO) today announced earnings for the first quarter of fiscal 2006 of $2.3 million, or $0.13 per diluted share, as compared with earnings of $1.3 million, or $0.07 per diluted share, for the same period in fiscal 2005. The fiscal 2006 first quarter results include share-based payment compensation expense of $0.2 million ($0.4 million pre-tax), or $0.01 per diluted share. The fiscal 2005 first quarter results include a loss from discontinued operations of $0.01 per diluted share.

Beginning this quarter, Zygo Corporation adopted the provisions of Financial Accounting Standards Board Statement No. 123R, “Share-Based Payments (As amended).” This statement requires that the compensation expense resulting from all shared-based payment transactions be recognized in the financial statements. The statement of operations for the first quarter of fiscal 2006 includes pre-tax share-based payment compensation expense of $0.1 million in cost of goods sold, $0.2 million in selling, general, and administrative expense, and $0.1 million in research and development expense.

Net sales for the first quarter of fiscal 2006 increased 25% to $34.6 million as compared with the prior year first quarter. Backlog at September 30, 2005 totaled $70.6million, an increase of $4.0 million, or 6%, from June 30, 2005 and of $9.2 million, or15%, from September 30, 2004.

Orders for the first quarter of fiscal 2006 were $38.6 million as compared with $34.1 million for the first quarter of fiscal 2005. Orders from the Company’s semiconductor segment accounted for 52% of the orders received, with the industrial segment accounting for 48% of the orders.

“We are very pleased with the continued strong financial performance of our company,” stated Bruce Robinson, ZYGO’s Chairman and President. “The Company continues to make progress toward achieving our long term-objectives with a resulting positive effect on earnings. Orders were particularly strong for what is normally our seasonally weak quarter and market opportunities for our products look promising.”

Highlights for the first quarter of fiscal 2006 included:

• New orders were received for Generation 7.5 and OLED flat panel metrology.

• Orders for our semiconductor lithography products were up over Q1 of last year, and stronger than we had anticipated.

• An order for $3.8 million for opto-mechanical assemblies, related to the lasik eye surgery tool, supported indications of continuing acceptance in the market.

• EPS is up 86% over Q1 of last year.

Mr. Robinson closed his remarks by stating, “We are continuing to invest in new products and services for the semiconductor market. It is our belief that the strategy of transitioning from an OEM to a direct supplier will have a long-term positive effect on revenue and earnings growth.”

Zygo Corporation is a worldwide supplier of optical metrology instruments, precision optics, and electro-optical design and manufacturing services, serving customers in the semiconductor capital equipment and industrial markets.
