Abstract

Abstract

To get irradiation distribution of arbitrary form on a specific plane, the free-form surface reflector is constructed with the Supporting-Ellipsoid design method in this paper. Firstly, the design idea and design process are introduced, and then a specific optical system of free-form surface is constructed. Simulation results show that the system efficiency reaches 97% without regard to reflection loss, which is three times more than that of the optical system of traditional solar simulator. The irradiance non-uniformity reaches 5.26%, which has a certain gap with the ideal state, resulting from the consideration on both the calculate time and the smoothness of the free-form surface in the design.
