reflector 3 and is directed toward two optical rhomb elements 5 and 7 although rhomb elements are shown as a preferred method of beam splitting other devices such as tilted optical flats will also provide the necessary function the curved reflector is designed to provide a nearly collimated beam of light although it is preferred that the curved reflector make the collected beam collimated it is not essential for collimation may be easily accomplished by a simple lens element the two rhombs 5 7 are placed in close proximity so as to receive nearly all the light from the lamp source 1 as shown in fig1 the input beam gets split in two separate beams by the rhombs 5 7 which displace the two beams laterally and direct them parallel to the original optical axis to further identify the different beams rays 9 and 10 are part of the full beam whereas rays 11 and 12 are each part of one of the split beams each of the split beams is focused by a focusing lens 14 or 16 near the entrance of the two aperture ports 18 20 of the compact homogenizer assembly 22 the focusing lenses 14 and 16 focus the light rays into a specified angle for example angle 24 that defines the numerical aperture of the light bundle the compact homogenizer assembly 22 is made of a set of mirror strips and mirrored glass plates alternatively it may also be made of a.
