Abstract

Processing and compensating test of large convex spherical lens is a complicated problem for the time being. In this paper, based on the theoretical analysis and our practical experience of lens processing, a new processing technique and a null compensating test method, or called inner measurement, to the large caliber convex sphere is presented. This processing technique can effectively overcome the deformation in the influence of the gravity and support. Meanwhile this inner measurement can also overcome effectively the defects of the template method to the surface finish quality of the test elements and the problem of deficiency of the measurement aperture. This method can obtain high machining and measurement accuracies.
