Abstract (en)
[origin: WO2006086458A2] A multi-colored illumination system comprising a beam combiner. The beam combiner comprises two triangular prisms and a filter for transmitting a first light and reflecting a second light, each light having a different wavelength. The beam combiner combines the transmitted first light and the reflected light to provide a combined beam. The six surfaces of each of the triangular prism of the beam combiner is polished, thereby combining the lights without increasing etendue of the multi-colored illumination system.
