Abstract: A solar simulator includes a light source having an optical axis linearly elongated, a feed means for feeding a long continuous film-shaped irradiation object, and a position regulating means for regulating the long continuous film-shaped irradiation object in position to surround the light source so that a center of the long continuous film-shaped irradiation object is coaxial with the optical axis. The long continuous film-shaped irradiation object regulated in position is irradiated with light from the light source.

Abstract: A solar simulator includes a light source, an optical reflection element positioned behind the light source to reflect light emitted from the light source in a form of pseudo parallel light, a low-angle light-diffusion optical element for diffusing the reflected light from the optical reflection element at a low diffusion angle, and a parallel light conversion optical element including a number of air holes arranged in parallel rows and provided with faculties for transmitting incident light parallel to the axis of the air holes to absorb or attenuate nonparallel incident light. The parallel light conversion optical element converts the incident light from the low-angle light-diffusion optical element to parallel light and emits the converted parallel light.
