As we know ZYGO continues to maintain the leadership role in surface form metrology using laser interferometry. It main measure radius of curvature, surface fringe and transmission wavefront distortion. Meanwhile, it can improve the accuracy and repeatability of the inspection process. Mainly for the flat surface, sphere, cylinder and so on.
Assuring the high surface accuracy, arrived λ/20
Main measure the focal length and centration. Automatic measurement, high efficiency of measurement;High accuracy, powerful function, wide range of measurement.
