HIGHLY COLLIMATED SOLAR SIMULATORS
A solar simulator (also known as "artificial sun") is a device that provides illumination approximating natural sunlight. The purpose of the solar simulator is to provide a controllable indoor test facility under laboratory conditions, used for the testing of solar cells, sun screen, plastics, and other materials and devices.
RotaLab provides highly collimated solar simulators in two different series: highly collimated fresnel lens solar simulators and ultra-high effiency solar simulators.
Conformity with ASTM, IEC and JIS standards about spectral matching, irradiance spatial non-uniformity and temporal instability is available for our highly collimated solar simulators.
