Catoptric lens arrangement
First Claim
1. A beam forming arrangement for forming a beam of wave propagated energy from the energy emitted by a source thereof, such arrangement comprising:
- a. at least a pair of mirrors having a common focal curve disposed around an axis of symmetry, one of such mirrors having a concave reflecting surface and the other having a convex reflecting surface to define a divergent channel for wave propagated energy, one of such mirrors being interposed between such channel and the common focal curve of such mirrors; and
b. a source of wave propagated energy disposed between the confocal mirrors and within the divergent channel adjacent to the narrowest part thereof.

Abstract
Improved catoptric lens arrangements to form beams from the energy emitted by extended sources of wave propagated energy are disclosed. All embodiments utilize at least a pair of mirrors disposed along a common axis, one of such mirrors being convex and the other concave, the generatrices of the reflecting surfaces of such mirrors being curves with coincident focal points, such generatrices being always divergent. At least one source of wave propagated energy is disposed between such reflecting surfaces so that all of the wave propagated energy from such a source is reflected back and forth between the mirrors in passing to an exit aperture defined by the mirrors.
