Compound Parabolic Concentrators (CPCs) are concentrator lenses made from rotated parabolic shapes to create specific acceptance angles through which divergent light is collected. Monica Rainey, Optical Engineer, explains the common features and applications of CPCs.
Want to collect and concentrate divergent light while avoiding the difficulties associated with multi element system? If so, compound parabolic concentrators known as CPCs may be the choice for you. A CPC is a concentrator designed using a rotated parabolic shape. The wide end of the CPC collects divergent light, which is then reflected within the CPC and concentrated at the narrow output end. CPCs are defined using an acceptance angle which is the angular range in which a CPC can collect light CPCs are ideal for any application that requires the condensing of divergent lightsources and are commonly used for solar energy collection, wireless communication, and biomedical and defense research.
