ABSTRACT:
A lamp comprised of a light source and reflector wherein the reflector is comprised of a plurality of annular segments which are arranged with respect to the source and a target to be irradiated so that points on the target receive radiation which is reflected from a different number of segments with points on the target which are closer to the periphery thereof receiving radiation which is reflected from a greater number of segments then points which are closer to the center of the target in such manner that due to the increase in target area in a direction from the target center to periphery the radiation incident across the entire target area is substantially uniform, and whereby the average local divergence of radiation incident on the target is minimized and spatial non-uniformities are relatively averaged.
