Title:
NON-IMAGING PHOTON CONCENTRATOR
Document Type and Number:
WIPO Patent Application WO2004059990
Kind Code:
A3
Abstract:
A photon concentrator includes an imaging photon concentrator (13) concentrating photons from a source (70) to an image point (14) and a non-imaging photon concentrator (30). The non-imaging photon concentrator (NIPC) has an entry aperture (33) coupling to the imaging photon concentrator near the image point. The NIPC also includes an exit aperture (35) wherein the entry aperture is larger than the exit aperture.
