Compact interferometer for precise shape testing of large-size convexaspherical mirrors

A model of an interferometer for testing of convex aspherical mirrors up to 250 mm in diameter based on the scheme of orthogonal rays is presented. An algorithm for interferogram processing has been developed. The results of measurements of the profile of a convex spherical mirror on the presented i...

Description
Summary:A model of an interferometer for testing of convex aspherical mirrors up to 250 mm in diameter based on the scheme of orthogonal rays is presented. An algorithm for interferogram processing has been developed. The results of measurements of the profile of a convex spherical mirror on the presented interferometer are presented.
