Stray light analysis of an on axis three reflection space optical system
Stray light analysis of a three-mirror spatial optical system is presented. The entrance pupil diameter (EPD) of the system is 320 mm, the e?ective focal length (EFL) is 2809 mm, and the field of view (FOV) is 1°×0.5°. Its walls are coated with extinction paint (the absorption coeffcient of which is
