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]
What it is
The Zygo GPI XP is an interferometer used for noncontact measurement of optical surfaces and components. The GPI XP uses a 640-by-480 pixel CCD camera and MetroPro software version 8.3.5. The system includes a 4-inch transmission flat (FT) lens attachment for f-ratio measurement.[2]
