Abstract
A two stage non-imaging optical concentrator providing high concentration while providing a low aspect ratio and a wide field of view. The invention includes a non-imaging refractive member and a non-imaging reflective funnel member. The reflective funnel has a broad extremity and an opposing narrow extremity. The refractive member is disposed substantially within the funnel, proximate to the narrow extremity of the funnel, so as to provide a low aspect ratio of the two stage non-imaging concentrator of the invention. The low aspect ratio of the concentrator of the invention advantageously provides for compact and efficient packaging of the concentrator in conjunction with mobile optical communication link components.
