<p>A Spectrally selective light splitter divides white light into red, green and blue light or recombines white light from red, green and blue light. The light splitter comprises two separate layer systems 5, 7 each reflecting or transmitting colour-selectively. The layer systems are applied or embedded on or in at least one transparent base body such as X-cube 7. The base body determines emergent faces K R, G, and B each for the red, green and blue light and the light is reflected by light valves RLV B, G, and R. At least one emergent face is tilted with respect to the direction of the light emerging from it and reflected on at least one of the layer systems such that its face normal F RLV encloses with this direction an angle d which deviates from zero, specifically by more than is caused by the production tolerances of the light splitter, and for which d & 5{. The tilting may also be due to the cube being tilted with respect to the incoming light (see Fig 16), in which case the layer systems can be diagonal.</p> |
