Abstract:
A collecting and condensing apparatus comprising:a source of electromagnetic radiation, said source having a first width; a first light pipe, said first light pipe having a first input end and a reflective end, said input end having a second width; a second light pipe disposed parallel to said first light pipe, said second light pipe further having an second input end juxtaposed to said first input end of said first light pipe and an output end, said second input end having a third width; a first reflector having a first optical axis and a first focal point on said first optical axis; a second reflector having a second optical axis and a second focal point on said second optical axis disposed substantially symmetrically to said first reflector such that said first optical axis is substantially collinear with said second optical axis; said source being located substantially proximate to said first focal point of said first reflector to produce rays of radiation that reflect from said first reflector to said second reflector and substantially converge at said second focal point; an additional reflector constructed and arranged to reflect at least part of a portion of the electromagnetic radiation that does not impinge directly on said first reflector toward said first reflector through the first focal point of said first reflector to increase a flux intensity of the converging rays; and wherein said first and second input ends of said light pipes are located substantially proximate to said second focal point of said second reflector to collect said electromagnetic radiation.
