Abstract :
This paper designs a total of 250 mm dual-channel optical system, including visible (0.5 μm~0.8 μm), infrared (3 μm~5 μm). The main system is a three-reflection system, and the primary mirror is designed as the first and the third reflecting surface with different figuring. The cooling infrared detector was choiced in infrared channel and achieves 100% cool shield efficiency of luminescence through the second imaging. The main benefits of this design are the large corrected and unvignetted FOV, an easily baffling of stray light, small encumbrance and an easy handing.
