Abstract:
A light collection system comprising a parabolic reflector, the parabolic reflector comprising a compound parabolic reflector surface having a first focal point and a second focal point, the compound parabolic reflector surface comprising a primary parabolic reflector section defining the first focal point and a secondary parabolic reflector section defining second focal point, the sections being paraboloid sections and being positioned coaxially with respect to one another, so that a light source placed at the first focal point defined by the primary parabolic reflector section is imaged at the second focal point defined by the secondary parabolic reflector section,characterized in that the secondary parabolic reflector section is divided into a plurality of segments, whereby for each segment, a separate focal point is defined and a separate image is produced.
