ABSTRACT:
A system for providing illumination includes a color mixing rod integrator for receiving and homogenizing laser light or output to a spatial light modulator. The rod integrator recombines the light of the primary colors, thus obviating dichroic recombination optics. Entrance and exit faces of the integrator have reflective layers where the length of the integrator is decreased and/or the f-number in the system is increased.
