Abstract:
An optical array converting UV, visible and IR radiation, especially contained in sunlight, comprising:a system of absorptive filters, made of M1 material, to modify transmission characteristics, this M1 material is characterized by internal transmission for a given wavelength divided by its internal transmission for 310 nm light within the following range: between 0 and 0.7 for &lgr;=290 nm, between 0.3 and 1.5 for &lgr;=300 nm, between 0.5 and 2.0 for &lgr;=320 nm, between 0.5 and 3.0 for &lgr;=330 nm, between 0.5 and 2.0 for &lgr;=340 nm, between 0.5 and 1.7 for &lgr;=350 nm, between 0.1 and 1.5 for &lgr;=360 nm, between 0.01 and 1.0 for &lgr;=370 nm, between 10E-5 and 10E-1 for &lgr;=380 nm, between 10E-12 and 10E-2 for &lgr;=390 nm; a system of interference filters to modify transmission characteristics; and a scatterer at the beginning of the optical path to achieve non-directional spectral transmission characteristics of the array and to improve the spectral transmission characteristics of the array.
