ABSTRACT:
An improved illuminating system for redistributing incident radiation, having a non-uniform intensity distribution, to resultant radiation, having a narrower desired intensity distribution in a predetermined region of an output plane, the illuminating system comprising a redirecting surface of a lens or reflector, for relocating at least a portion of the incident light. In one application, particles are illuminated in the output plane.
