Abstract
A four mirror afocal optical system is disclosed. The primary mirror (12), secondary mirror (14), tertiary mirror (16), and quaternary mirror (18) form an afocal reimaging optical system which is off axis in both aperture and field angle. The secondary, tertiary and quaternary mirrors are tilted and decentered relative to the optical axis of the primary mirror to enhance image quality and to provide access to a real exit pupil.
