Abstract

A condensing and collecting optical system comprises two asymmetric reflectors. The first and second reflectors comprise a portion of an ellipsoid or paraboloid of revolution having parallel optical axis. A source of electromagnetic radiation is placed at one of the focal points of the first reflector to produce radiation that is received by the second reflector, which focuses the radiation toward a target. To achieve maximum output coupling efficiency, the second reflector has a different focal length than the first reflector such that the radiation inputted to the target has lower angle of incidence.
