The Zygo GPI XP Interferometer is a phase-modulating interferometer for noncontact measurement of flat or spherical surfaces and transmitted wavefront measurement of optical components. The GPI XP/D uses precision phase modulation while a 640 x 480 CCD camera captures several fringe images analyzed by MetroPro software.[1]
How it works
The GPI XP/D uses precision phase modulation for data acquisition. The GPI XP/D modulates the interferometric cavity length during measurement while a 640 x 480 CCD camera captures several fringe images. MetroPro analyzes those fringe images to create a detailed measurement of the part being tested.[1]
Applications
The GPI family is used for noncontact measurement of flat or spherical surfaces and for transmitted wavefront measurement of optical components and assemblies. The GPI family measures glass or plastic optical components such as flats, lenses, and prisms. The GPI family also measures precision metal components, polished ceramics, and contact lens molds.[1]
