SOLAR SIMULATOR

摘要

Disclosed is a solar simulator provided with a light source; a reflective optical element which is provided on the back side of the light source and which reflects light emitted from the light source, as pseudo-parallel light; a low-angle light diffusion optical element which diffuses light from the reflective optical element at a low diffusion angle; and a parallel light conversion optical element comprised of a number of air holes arranged in parallel with one another, each air hole having characteristics that incident light parallel to the axis of each air hole passes through the air hole, and nonparallel incident light is absorbed or attenuated, said parallel light conversion optical element converting incident light from the low-angle light diffusion optical element into parallel light and emitting the parallel light.
