Abstract

A solar simulator that simultaneously solves problems of high parallelism and high illuminance of emission light and increases uniformity of the emission light is provided. The following is an examiner's statement of reasons for allowance: Instant application claims and discloses a solar simulator that allows light radiated from a light source to be incident on an integrator, allows light emitted from integrator to be incident on a collimation lens, and allows parallel light to be emitted from collimation lens when a circumradius of integrator is r, a parallelism angle of parallel light is .phi., and a focal distance of collimation lens is f=r/tan.phi., focal distance f is selected so parallelism angle .phi. becomes less than 2.5.degree., and when an emission angle of light emitted from integrator is .theta., a diameter of collimation lens is D, and a viewing angle of collimation lens when viewed from integrator is .theta.X=2.times.a tan (D/2f), emission angle .theta. is configured to be smaller than viewing angle .theta.X. The combination of limitations claimed is not found, taught or suggested by the prior art.
