Innovation In Optics Solar Simulator
The LumiSun™ series includes innovative, compact benchtop LED solar simulator that meets IEC 60904-9, 60904-3 Class A+A+A+ for spectral match, nonuniformity of irradiance, and temporal stability. Output power can be varied from 0.1 to 1.2 SUNS, and user-friendly operation is supported by advanced GUI. Remote digital control is enabled by an RS-485 interface with Modbus RTU communication protocol. Wavelength Opto-Electronic is the partner of Innovation In Optics for Singapore.

Innovation In Optics Solar Simulator Information
LumiSun-50 incorporates the same Innovations in Optics’ [IOI] IP as OEM solar simulators sold in the thousands to leading PV manufacturers. IOI’s patent pending light collection optics and thermal management enable superior temporal stability and uniformity not only for the entire spectrum, but for individual wavelengths as well. LumiSun-50 provides A+A+A+ illumination over a 50x50mm area, making it ideal for use in research labs to measure the efficiency and spectral response of PV cells, as well as a range of other applications such as photobiology, solar degradation, and other sunlight research studies. Unlike bulky, expensive, environmentally unfriendly lamp-based units, LumiSun-50 employs a multi-wavelength array of long lifetime LEDs that are driven independently and can be user-controlled to set spectra. The LED light source is thermoelectrically cooled and contained within an air-cooled housing that can rotate the angle of the illumination plane. The optimal working distance is adjusted by converging a pair of red dots from integrated laser pointers.
