Abstract

In this paper the new modification of Hindle scheme for interferometric testing of convex hyperbolical surfaces is presented. It has a number of advantages and can be used to obtain undependable quality data of aspherical surface manufactured in another testing scheme. The advantage of the new Hindle scheme modification is the decrease of sizes in comparison with the classical Hindle testing scheme, the absence of additional compensators, the convenience of alignment and calibration, and the possibility of IR interferometers application during testing surface grinding. The suggested principle can be used during convex paraboloids testing.
