Abstract

An optical design was done for a system having a wide field of view with diffraction limited resolution over a 5° by 10° FOV. The length of the system including a baffle was set such that the earth does not illuminate the primary mirror at an angle of 1.66°. The system was analyzed using APART and, with the results of the stray light analysis, improvements were made allowing a focal plane irradiance of less than 10- 11 W/cm2 from the earth as a thermal source. Thermal self emission was also analyzed using APART allowing the temperature of the telescope walls to be specified.
