Abstract
A Cassegrain optical system has a concave primary mirror deployed for receiving incident electromagnetic radiation and generating once-reflected rays, a convex secondary mirror deployed for receiving the once-reflected rays and generating twice-reflected rays, a tertiary reflector deployed for receiving the twice-reflected rays and generating thrice-reflected rays, and a beam-folding optical element deployed between the primary mirror and the secondary mirror for deflecting the thrice-reflected rays laterally so as to exit a volume between the primary and secondary mirrors.
Claims11
A Cassegrain optical system comprising:
- (a) a concave primary mirror deployed for receiving incident electromagnetic radiation and generating once-reflected rays;
- (b) a convex secondary mirror deployed for receiving the once-reflected rays and generating twice-reflected rays;
- (c) a tertiary reflector deployed for receiving the twice-reflected rays and generating thrice-reflected rays;
- and
- (d) a beam-folding optical element deployed between said primary mirror and said secondary mirror for deflecting the thrice-reflected rays laterally so as to exit a volume between said primary and secondary mirrors.
