摘要

A kind of three mirror anastigmat (TMA) was described. All the system surfaces are uncoaxis with the off-axis telescopes, and avoid the affection of the central obstruction. The system is 15 m focal length, and 5.0°×0.4° field of view, while the total length of the system is f'/3.5-f'/3.0. The evaluation shows that the image quality is nearly diffraction limit.
