About the LumiSun-220

The LumiSun-220™ is a cost-effective LED solar simulator delivering Class A+A+A+ performance over a 220 mm × 220 mm area at a 600 mm working distance. It features 36 individually controlled wavelengths from 350 nm to 1250 nm with minimal spectral deviation. Irradiance is adjustable from 0.1 to 1.2 Suns in steady-state or pulsed modes. TEC cooling and closed-loop current control ensure excellent temporal stability and long-term reliability.

LumiSun-220™ leverages the same IOI intellectual property as our OEM solar simulators sold in the thousands to leading PV manufacturers. Patent-pending light collection optics and thermal management deliver uniform, stable output across the full spectrum and individual wavelengths. With LED lifetime exceeding 20,000 hours, it is a durable and flexible tool for advanced solar simulation.
