Abstract

A new relayed three-mirror anastigmat (TMA) optical form is presented in this paper. Although several variants of the form, are shown, the most interesting is one that utilizes spherical secondary and tertiary mirrors in conjunction with a point testable ellipsoid primary. The designs are especially suited to high aspect ratio line fields of view (FOV). Exceptionally good correction of aberrations and a number of other desirable features principally related to pupil imagery are exhibited for FOVs from 1 X 7 degrees, 1 X 10 degrees, 1 X 12 degrees up to a 30 degree line. The highly practical nature of the form for many applications is established through theory and example.
