Abstract
A high fidelity dual source solar simulator that provides a higher fidelity spectral match to the Air Mass Zero (AM0) solar spectrum and is derived from ultraviolet (UV) and visual light from a xenon arc lamp which is band pass filtered by a hot reflective mirror and slope filtered by a color glass filter, with the infrared (IR) light from a tungsten lamp which is band pass filtered by a cold reflective mirror and slope filtered by a thin film filter, so that, when the xenon and tungsten light components are combined as spectral segments, the spectra of the simulator matches both the curve shape and integral energy of the AM0 spectra while attenuating optical spikes so as to provide high fidelity over the entire AM0 spectrum.
