Abstract

A systematic performance analysis of aplanatic Gregorian type telescopes has been carried out by means of a ray trace program. A comparison of the results with those of the first part of this article [ C. L. Wyman and D. Korsch, Appl. Opt. 13, 2064 ( 1974)] for aplanatic Cassegrains shows that the dependence of the performance on the system parameters is more complex for the Gregorian. Plots of the image curvatures as a function of the ray height ratio are shown for several secondary magnifications and a system focal length of 1000 cm.
