A hybrid optical component that collects and concentrates incident light. The hybrid component includes both refractive and reflective elements. In preferred embodiments, refractive and reflective components focus rays on a common focal plane generally located at the bottom of the reflector where they are absorbed by a device such as a photovoltaic (solar) cell. Additionally, the optical component combines both imaging and non-imaging optical elements into a single device, for improved overall performance.
