Abstract
We present a three-mirror anastigmat(TMA) optical system for New Generation GOCI. In order to reduce the ghost optimized filter and baffle. By using carefully chosen antireflective coating and tilted filter angle, we fulfilled the design SNR requirement of 1500. We then designed a new entrance baffle and an internal baffle capable of producing the ghost ratio better than 0.01% of the nominal signal. The entrance baffle limits FOV to
