Abstract:
A solar simulator, comprising:a radiation source generating radiation having a spectral distribution predominately corresponding to a spectral distribution of sunlight; at least one filter arranged near the radiation source so as to be movable, substantially perpendicular to an irradiation direction of the radiation source, said filter suppressing long wave or short wave radiation components from the radiation source and said filter being also moveable to filter a variable portion of the irradiation as the at least one filter moves in said perpendicular direction; an irradiation plane adapted to accommodate objects to be irradiated, said plane being set at a distance from the radiation source and the at least one filter such that radiation coming directly from the radiation source, as well as the at least one filter, impinges on the radiation plane as essentially homogenous radiation of a punctiform light source.
