Abstract
A solid catadioptric lens (10) includes substantially planar input surface (14), primary concave mirror 18, secondary convex mirror (22) and substantially spherical exit surface (24). The lens is composed of solid material (12) chosen according to the particular imaging application in which the lens is to be used. Radiation enters lens through input surface (14), travels through solid material (12) and is reflected off of primary mirror (18). Radiation subsequently passes internally through solid material (12) and is reflected off of secondary mirror (22). Subsequent to being reflected off of secondary mirror (22), radiation (30) passes through solid material (12) and out of lens (10) through spherical exit surface (24) and onto detector array (34) for imaging purposes.
