Abstract
A holder includes a support member and a reflector coupled to the support member. The reflector comprises a reflecting member with a predetermined focal axis for reflecting a portion of electromagnetic radiation in a preselected direction from an electromagnetic transmissive envelope placed adjacent the reflector. The envelope comprises an elongated source of electromagnetic radiation extending between two points within the envelope and which is displaced from a straight line. Rotatable receiving assemblies mounted to the support member position the envelope adjacent to the reflector with the envelope axis substantially parallel to the focal axis where rotation of the envelope axis around the focal axis compensates for the displacement of the elongated source.
