Abstract

A novel aspheric surface testing method using part-compensating lens is presented in this paper. Researches are made to the specific design requirement and design method of part-compensating lens. The design requirement is applied in the optimization design of the part-compensating lens to three kinds of aspheric surfaces, and it is proved that the structure of part-compensating lens is much simpler than that of null compensator. Analysis is made about the asphericity compensation range of each part-compensating lens, some range can be 30 λ. The results demonstrate that aspheric surfaces with different relative aperture and asphericity can be compensated by part-compensating lens that is simple and easily fabricated, and the shape error of aspheric surfaces can be measured.
