Abstract
A projector has a transmissive spatial light modulator backlit by a collimated illuminator that includes a light source that outputs red, green, blue (RGB) light, and a combiner disposed in light-receiving relation to the light source for mixing or combining the RGB light. The combiner has cavity features associated therewith for outputting collimated light, where such light preferably has a divergent cone angle less than plus or minus fifteen degrees (+/−15°).
