Large Area LED Based Solar Simulator
The ISOSun Pro Solar Simulator is a large-area laboratory solar simulator designed to provide stable illumination across the 385–1300 nm spectral range. With 20 independently tunable LED wavelengths, it enables precise reproduction of both indoor and outdoor spectra, including AM1.5G. Outstanding performance in spectral match, spatial uniformity, and temporal stability makes the ISOSun Pro a reliable and consistent platform for accurate measurements.

Data and Specifications
Spectral Irradiance
Easy tuning of the 20 independent LED wavelengths, spanning a spectral range of 385–1300 nm, enables accurate reproduction of indoor and outdoor spectra, including AM1.5G. The included software makes it easy to find the lamp settings that best match a given reference spectrum and in addition to relative tuning of the individual colours, the lamp allows the overall light intensity to be scaled uniformly across all channels.
Spatial Uniformity
Spatial uniformity measures how evenly light is distributed across the test plane. The ISOSun Pro achieves A+ uniformity (≤1%) over its core area and Class A or better across the majority of the field. The result: reliable, high-precision testing of solar cells at any size
Temporal Instability
The ISOSun Pro shows excellent stability over time being class A+ in both short-term and long-term temporal instability. The high stability over time allows for consistent measurements of your devices.
