A highly efficient optical device comprises two opposing active non-spherical optical surfaces defined by a two-dimensional representation that is symmetrically extended to provide a three-dimensional device. A focal area, spaced apart from the optical surface and non-contiguous therewith, is defined by the two opposing active optical surfaces. The active optical surfaces each have a continuous second derivative, and the optical surfaces are defined by a polynomial with an order of at least about twenty. The optical device may comprise a transparent dielectric core, and the optical surfaces may be formed on the core. A receiver may be situated at the focal area to provide a concentrator. An extended light source such as an LED may be situated at the focal area, to provide a collimator. Faceted embodiments can provide a low aspect optical device. In some embodiments a diffuser may be used to transform incident radiation into a predetermined shape.
A method of manufacturing an optical device having two opposing active optical surfaces that convert a first distribution of an input radiation to a second distribution of output radiation, comprising:
