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: Electro-Optics 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. Founded in 1970, and headquartered in Middlefield, Connecticut, USA, ZYGO's global operations are supported by approximately 500 dedicated and highly-skilled individuals around the world.
