Abstract

A photon concentrator includes an imaging photon concentrator concentrating photons from a source to an image point and a non-imaging photon concentrator. The non-imaging photon concentrator (NIPC) has an entry aperture coupling to the imaging photon concentrator near the image point. The NIPC also includes an exit aperture wherein the entry aperture is larger than the exit aperture.
