This paper describes the optical design, fabrication and use of single element null lenses for the interferometric testing of generalized aspheric surfaces. The aspheric singlet is designed to work in collimated light, without a field lens, and allows for measurement of surface figure error over the entire clear aperture. The null lens is a single element… CONTINUE READING
