Paper Abstract

TMA (Three Mirrors Anastigmatic) can simplify the configuration of telescope and lighten the weight, so it is very popular to the design of space-based optical system. According to this concept, an off-axis unobstructed TMA is calculated. Based on initial configuration parameters, automatic optimization is executed in ZEMAX program, and a new telescope is obtained with parameters as follow: aperture is 2000mm, f/number is 2.25, FOV is 5°, angular resolution is better than 7 μrad and image quality meets limited performances.
