Innovations in Optics Inc. has introduced its Model 2910A-300 multi-wavelength LED illuminator for testing photovoltaic devices. The company says the unit meets IEC 60904-9 Class AAA solar simulator requirements for spectral match, uniformity of irradiance and temporal stability.
The 2910A-300 achieves a spatially uniform illumination field by combining chip-on-board LED technology with non-imaging, homogenizing optics and a precision re-imaging lens system. The field of illumination is 5 x 5 cm at a working distance of 20 cm.
The 2910A-300 uses seven LED spectral bands to cover a spectral range of 400-1,100 nm. Total irradiance of 1.1 sun units in the spectral range is provided while operating electrically at 85 W.
Primary applications for the 2910A-300 are in terrestrial PV testing and research. The compact light source measures 10 cm long by 3 cm diameter and is suited for system integration. Multiple units can be combined for illuminating larger areas. System accessories include thermal management devices, wire harnesses and driver/controllers.
