Xenon Arc Lamp Solar Simulator

Solar simulators based on lamps other than high pressure xenon arcs produce spectra that are poorly matched to the solar spectrum with the exception of the impractical carbon arc simulator.

Xenon arc lamp solar simulator. For the closest match possible choose a sol3a class aaa solar simulator for class a spectral match class a spatial irradiance uniformity and class a temporal stability as required by. These lamps offer high intensities and an unfiltered spectrum which matches reasonably well to sunlight. Sciencetech manufactures light sources solar simulators monochromators and other optical spectroscopy instruments. However the xe spectrum is also characterized by many undesirable sharp atomic transitional peaks making the spectrum less desirable for.

94023a solar simulator class aaa iec jis astm 450 w xenon 2 x 2 in. The main reason for this is that it provides a stable spectral that matches reasonably well to sunlight even unfiltered. Simulation with tungsten lamps. Their sun like emission spectrum and 5800 k color temperature make them a popular choice for solar simulation as well as absorption and fluorescence and source spectral scanning applications.

Xenon arc lamps are the most widely used light source for solar simulators. Arc lamp solar simulators. Metalhalide and xenon arc lamps provide a good spectral match to the solar output. This is the most common type of lamp both for continuous and flashed solar simulators.

Sciencetech custom engineering solutions sciencetech s in house team of designers and engineers have decades of combined experience in the fields of optical spectroscopy and solar simulation making the company an ideal choice. Xenon arc lamps have a spectrum almost identical to that of a sun at 5800 k. A xenon arc lamp is a highly specialized type of gas discharge lamp an electric light that produces light by passing electricity through ionized xenon gas at high pressure. Light sources used for solar simulators in thermal applications are reviewed.

An ideal spectral match for a solar simulator is based on the percentage of the integrated light intensity in 6 spectral ranges. A solar simulator with a class a spectral match may not deviate more than 0 75 to 1 25 times the ideal percentage in each spectral range. Lamp types are discussed argon arc metal halide tungsten halogen lamp and xenon arc. Xenon xe arc lamps have a relatively smooth emission curve in the uv to visible spectrums with characteristic wavelengths emitted from 750 1000 nm.

It produces a bright white light that closely mimics natural sunlight with applications in movie projectors in theaters in searchlights and for specialized uses in industry and research to simulate sunlight often for. Guidelinesfor lamp selection based on user requirements and criteria are presented.
