Based on third class optical aberration theory,a kind of three mirror anastigmatic system (TMA)with wide field of view (FOV)and compact construction is studied.On-axis system design is employed,and offset the FOV is used with double folded mirrors (DFMs)being inserted to compress.The primary mirror is segmented,and analysis the error character.A TMA system is introduced with 22m focal length,0.8°×0.1°field of view (FOV).By using the DFMs,the total length is about f′/5~f′/5.5.
