The story
The company was founded in 1970 by Paul Forman, Carl Zanoni, and Sol Laufer, with financial support from Canon Inc. and Wesleyan University. An initial priority for the company was to build a world-class optical fabrication facility for producing optics with the highest precision plano surfaces and angles.
It was recognized that in order to achieve such a goal, practical and easy-to-use interferometry would have to be a standard part of the fabrication process. While there were several interferometers available on the market at that time, none had all the flexibility or features needed for Zygo's facilities and were also extremely cost-prohibitive. An interferometer was developed in 1972 for these in-house purposes, the Model GH, and it later became Zygo's first commercial product with a second model, the Mark II, being its breakout success in 1976.
In the 1990s, Zygo expanded its offerings to include software designed for lower cost personal computers and brought to market its ZMI metrology lasers.
In October 2008, competitor ESI attempted to acquire Zygo for approximately 174 million USD worth of stock but the buy-out was stymied by Zygo's board of directors. Zygo later became part of the Ultra Precision Technologies Division of Ametek, Inc. as a result of a 2014 acquisition.
In 2022, Zygo announced a further expansion into Europe with a new office location in Italy. With an established office in Germany along with a partner network across additional European countries, the Italy office will support Zygo's European customer base.
