Abstract

This paper presents the results of the optical design tradeoff study that result in a reduction in complexity, size and cost of the structure for the sub-millimeter 25 m class CCAT telescope. Four optical configurations are presented; dual reflector Cassegrain and Gregorian options, and Gregorian Nasmyth and quasi-Nasmyth options. All configurations are shown to have diffraction limited performance.
