An innovative benchtop LED solar simulator, LumiSun™ 50 is perfect for measuring photovoltaic cells’ efficiency and spectral response in research labs. Photochemistry, photobiology, materials testing – all these use cases benefit from LumiSun™ 50’s performance
Featuring the same LED array and optics architecture as Innovations in Optics’ OEM solar simulators favored by leading PV manufacturers worldwide. LumiSun™ 50 lives up to Class AAA IEC 60904-9 Ed. 2, ASTM E927-19, and JIS C 8904-9 standards for spectral match, uniformity of irradiance, and temporal stability.
Innovations in Optics’ patented light collection and projection optics certainly benefit LumiSun™ 50’s performance: It provides a 50 X 50 mm illumination field with excellent uniformity, outshining other LED-based designs on the market today. Unlike conventional solar simulators equipped with discharge lamps, LumiSun™ 50 incorporates a multi-wavelength array of long-lasting LEDs.
This unit features three preset solar reference spectra that emulate sunlight with remarkable accuracy. You can also configure user-defined spectra by controlling all installed LEDs individually and adjust LumiSun™ 50’s irradiance from 0.1 to 1.5 SUNS.
Setting up the LumiSun™ 50 solar simulator is an exercise in convenience. The LED light source sits in a freely rotatable air-cooled housing. A converging pair of red dots from integrated laser pointers helps you find the optimal working distance. An RS-485 interface with Modbus RTU communication protocol is built in to enable remote control.

1The total solar irradiance of the AM1.5 Global Spectrum (AM1.5G) is defined as 1,000 W/m2 integrated over a 0 – 4,000 nm wavelength interval. The above total of 908 W/m2 is an abridged definition of 1 SUN irradiance when integrating over the 400 – 1,100 nm interval. See the ASTM G173−03 (2020) reference solar spectrum.
