Abstract
A faceted surface has first and second facets which deflect respective first and second light beams to produce first sub-beams which alternate with second sub-beams. The faceted surface may be a reflector having first facets at 120° to second facets for mixing light beams which are incident at 120° to each other. 100% of reflected sub-beams from each source alternate with 100% of sub-beams from the other source. The faceted surface may also be a refractor which is part of a transparent block having two parallel faceted surfaces. A first refractive surface refracts parallel light beams to produce diverging beams which are each split into spaced apart sub-beams by the second refractive surface. 50% of refracted sub-beams originating from each source alternate with 50% of refracted sub-beams of each adjacent source.
