Paper Abstract

An "unusual" optical surface is the plane symmetric equivalent of the general rotationally symmetric aspheric familiar to optical designers. This surface was introduced to facilitate the design of fast, unobstructed aperture, large field-of-view, reflecting telescopes, and has resulted in a number of successful designs of such systems. The fabrication of these systems is inhibited primarily by the difficulty of testing such surfaces, so in this paper we describe an appropriate test procedure. This is an interferometric method that makes use of a hybrid setup in the test arm where the geometry, test optics, and a computer-generated hologram are all used to attain zero aberration.
