Interferometer
Brand: ZYGO
Model: Verifire MST
Function: Mainly used for precise measurement of various plane and spherical reflective surfaces and surface shapes of optical systems, transmission wavefront of optical systems, wedge angle test of prisms, etc., and material uniformity test and analysis. Using helium-neon laser (633nm), Fizeau phase shifting method, online measurement of the measurement beam diameter is 52mm (6"). The standard mirror accuracy is 1/20 wavelength, CCD resolution can reach 1000*1000, RMS simple repeatability<0.06nm.
Surface shape is a very important parameter of optical lenses. By using Zygo MST 12 interferometer, the surface shape of lenses of various sizes can be measured, which can be used to analyze the characteristics of thin film surface shape, lens surface shape change before and after coating, etc. By rationally utilizing materials and processes, the surface shape change before and after coating can be small, ensuring the surface shape requirements of optical components.
