Abstract
A reflective afocal telescope is described herein that has multiple field of views and can be packaged in a compact arrangement. In one embodiment, the reflective telescope includes two entrance pupils, a primary mirror, a secondary mirror, a tertiary mirror, a quaternary mirror, a moveable fold mirror and an exit pupil. The fold mirror can be moved into a non-bypass position and out of the way such that the incident beams transverse the primary, secondary, tertiary and quaternary mirrors and form a collimated region and a real external exit pupil. Or, the fold mirror can be moved into a bypass position where the incident beams bypass the primary, secondary, tertiary and quaternary mirrors and instead reflect off the fold mirror directly to the exit pupil. In an alternative embodiment, the tertiary mirror instead of the fold mirror can be moved into either the bypass position or the non-bypass position.
