GPI™XP/D Laser Interferometer--using the principle of phase-shifting interferometry, provides high-precision planar surface shape, ball face shape, curvature radius, sample surface quality, transmission wave front measurement and analysis. GPI™XP/D is a laser interferometer that Zygo has the highest market share in China and even around the world, and is widely used in scientific research teaching and production testing. GPI™XP/D host for Fizeau type interferometer, high precision and simple operation, the use of precision phase shifter technology and high-resolution CCD receiving device 640х480 (can be upgraded to 1024x1024), with powerful METROPRO® The software can obtain high repeatability and high precision measurement results, and its three-plate absolute measurement repeatability is better than λ/300,rms repeatability better than λ/10,000. It can simulate the surface shape of the sample, and display the vivid, rotatable 3D color image, the optional sectional view and various statistic results. At the same time, for special samples, special measurement needs, users can design customized special measurement system, combined with metropro® software, to provide users with the perfect technical solution and to obtain satisfactory measurement results.

Phase-shifting interferometer with digital camera providing 640 x 480 acquisition.
