ABSTRACT:
A device having an inner surface with a combination of reflective and refractive surface facets swept about an axis of revolution perpendicular to the optical axis of the device. The outer surface has a non-planar, non-circular, non-spherical shape. This outer surface generates an appropriate intensity distribution in a direction generally parallel to the major axis of the output rectangle and may also distribute energy generally parallelly to the minor axis of the output rectangle as well.
