Paper Abstract

Some years ago, the author pointed out that an optical surface concentric with the image point may be used to alter or correct astigmatism without substantially affecting the other aberrations. This principle is employed in the design of a two element aplanatic corrector lens used with the Ritchey-Chretien form of Cassegrain optical system to correct the latter's residual field curvature and astigmatism. A review of the background optics is given.
