Abstract

A reimaging three-mirror anastigmat has been developed to cover fields of view of up to 2 degrees by 9 degrees. By using the optical system on-axis with an offset field of view, a significantly larger field of view than has been reported up to now can be used with low obscuration. The concept of tilting and decentering optical elements for a field view 2 degrees square, which yields a significant improvement in image quality, is discussed.
