Abstract: An all-reflective optical system has a first (10) and second (12) reflecting assembly. The first reflecting assembly (10) includes an afocal three-mirror anastigmat (18, 20, 22) with one or more apertures (28 A-D) in the tertiary mirror (22) to enable light or energy to pass therethrough. Light or energy reflects from the second reflecting assembly (12) through the apertures (28 A-D) to provide simultaneous viewing of a scene by a plurality of instruments (34). The second reflecting assembly (12) includes a planar mirror which provides pointing and stabilization motions for all of the instruments simultaneously without degrading image quality or pupil registration.

Abstract: A non-relayed optical system is used off-axis in both aperture and field angle relative to an optical axis (32), and employs three reflective lens elements (34, 36, 38). The system is useful for viewing radiation from a distant object, the radiation allowed to enter the system through an opening in a real and accessible entrance pupil (44) that is disposed in front of a concave primary mirror (34). Because the entrance pupil of the system is real and not virtual, the aperture stop of the system is coincident with the entrance pupil, resulting in a significant reduction in beam wander about the front of the optical system. The real entrance pupil of the system also allows the system to be utilized for applications where it is required that the system view distant objects by means of a small viewing port, window or object space scan mirror.
