The simulator can be used to obtain a spectrum adjusted to the solar spectrum, both for a standard spectrum or a real spectrum adjusted to local irradiation conditions. The simulator also allows the spatial-angular characteristics of the sun to be reproduced. The invention comprises: a broad-spectrum light source, the flux from which is emitted through an aperture; an optical system which collimates the primary source; a system which disperses the beam chromatically; an optical system which forms an image of the dispersed primary source at a given position, at which a spatial mask is placed in order to filter the received irradiance spectrally; an optical system which captures the filtered spectrum and returns, mixes and concentrates same in a secondary source with the desired spectral, angular, and spatial characteristics; an optical system which collimates the secondary source such that it reproduces the angular characteristics of the sun; and a control system.engpatenthttps://patentscope.wipo.int/search/en/detail.jsf?docId=US73504551&recNum=1&maxRec=3&office=&prevFilter=&sortOption=Pub+Date+Desc&queryString=FP%3A%28Variable+spectrum+solar+simulator%29&tab=NationalBibliohttps://worldwide.espacenet.com/publicationDetails/biblio?CC=US&NR=2012057324A1&KC=A1&FT=D#open access535Spectrum solar simulatorSolar spectrumOptical systemÓptica (Física)2209.19 Óptica Física
