Optical imaging applications are broad and varied. Testing at a system's design wavelength is critical for final alignment and qualification, Night vision, IR and thermal imaging systems for aerospace and defense, lithography subsystems, remote sensing telescopes, and exotic material qualification represent broadly-varying wavelength requirements, and all benefit from testing at design wavelength with an infrared interferometer system. ZYGO, long recognized as the world leader in interferometric testing instruments, has designed and built many specially-equipped interferometer systems, including NIR, SWIR, MWIR and LWIR wavelengths. ZYGO also designs and manufactures an array of reference optics (transmission spheres and transmission flats) for these wavelengths.
