Zygo Corporation is a global leader in the design and manufacture of advanced optical metrology systems and ultra-precise optical components and assemblies.

Our mission is to enable customer success by delivering innovative precision optical and metrology solutions.

Our Metrology Systems business segment is comprised of three major groups: 3D Optical Profilers,  Laser Interferometers, and Nano-Position Sensors. The products and systems produced by these groups employ various optical phase analysis techniques for measuring displacement, surface shape and texture, and film thickness. Applications for our metrology products are diverse, and include precision machining, optical manufacturing, and semiconductor manufacturing, as well as many others.

Our Optics business segment is comprised of two major groups: Optical Assemblies and Optical Components. These groups leverage ZYGO's expertise in optical design and assembly, and high-volume manufacturing of precision optical components and systems, for aerospace, defense, medical, and industrial applications.

Recognized as a valued partner by its customers for innovative technology, application expertise, product reliability, and responsiveness, ZYGO leverages its core competencies in metrology and optics to enable its customers to be successful in their respective markets.

Throughout its history, ZYGO has been driven by a passion for innovation, as evidenced by approximately 750 patents awarded since the Company's founding.

In 2014, ZYGO became part of the Ultra Precision Technologies Division of AMETEK, Inc., a leading global manufacturer of electronic instruments and electro-mechanical devices. With annual sales over $4 billion, AMETEK has more than 15,000 colleagues at nearly 150 operating locations, and a network of sales, service and support locations across the United States and in 30 other countries. ZYGO enjoys mutually-beneficial relationships with its AMETEK sister companies, collaborating on technologies and sharing resources in order to provide the best possible experience for our customers.

While we are a part of the AMETEK family, we are still the same Zygo Corporation that you have known and trusted for over 50 years, committed to serving your precision metrology and optics needs now and in the future.
