FM/060-LP/LS Laser Sphere Interometers

Principle: Fizeau interferometer is a precise instrument based on equal thickness interferometer, which can detect the surface shape of optical elements, the wavefront aberration of optical lens and the homogeneity of optical materials. The measurement accuracy is generally 1/10-1/100, which is the average wavelength of the light source for detection.
