Zygo Laser interferometer

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
