<p>The projection unit has three light sources beaming light of different color spectrums. Light passes through liquid crystal display for each source and then to one side of dichroide device which has two color selective mirror surfaces tuned to the color spectrum of light sources (10,11). Mirror surfaces overlay single color channels to common beam path which meets lens with beam paths (d',d,d') between single light sources and lens having different lengths. Difference determined by distance of light source from dichroide body (13).</p> |
