Paper Abstract

This paper analyzed the structural and imaging features of off-axis three-mirror system, discussed the design method of the multi-channel off-axis three-mirror system. A new three-channel off-axis TMA optical system was designed using channel spectral separation. The system parameters are as follows: aperture is 300mm, FOV is 2°×2°, covering three spectral bands. According to the primary aberration theory, an appropriate initial configuration can be obtained. By optimizing the initial configuration, we can get an optical system which meets the imaging quality requirement. The design of relay lenses was also considered, the ultimate goal is to complete the design of each channel with the least number of lens.
