Dual paraboloid reflector and dual ellipsoid reflector systems with optimized magnification

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 towarda 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.

AI Technical Summary

Problems solved by technology

In particular, large divergence angles lead to the fact that light energy transmitted along a path similar to ray a will cover a relatively large area on the second parabolic reflector, resulting in unfavorable aberrations and loss of brightness

However, none of the references mentioned above describe a system capable of handling large angular divergences and optimizing the magnification between the source and the focused image to obtain maximum flux density at the target with minimum distortion
