An optical system has a controlled transmission mirror that includes a diverting layer, an output coupling element and a multilayer reflector disposed between the diverting layer and the output coupling element. The multilayer reflector is spaced apart from the diverting layer. At least a first light source has a light emitting surface positioned between the diverting layer and the multilayer reflector of the controlled transmission mirror.
