Abstract

A systematic performance analysis of aplanatic Schwarzschild-Couder type telescopes has been carried out by means of a ray trace program. The classic Schwarzschild and Couder designs were studied in detail. It was found that those types of telescopes, in contrast to the Gregorian [ Appl. Opt. 13, 2402 ( 1974)] and the Cassegrainian [ Appl. Opt. 13, 2064 ( 1974)] configuration, suffered severely from higher order aberration.
