ISOSun Pro Solar Simulator
Compact, large-area LED-based system designed to deliver stable and precise illumination across the 385–1300 nm spectral range.
Reliable, Large-Area Solar Simulation
The ISOSun Pro Solar Simulator is a compact, large-area LED-based laboratory system designed to deliver stable and precise illumination across the 385–1300 nm spectral range. Featuring 20 independently tunable LED wavelengths, it enables accurate reproduction of indoor and outdoor spectra, including AM1.5G. The system supports illuminated areas up to 1000 cm² and delivers intensities of up to 7 suns, with outstanding performance in spectral match, spatial uniformity, and temporal stability (up to class A+A+A+). This ensures reliable and consistent conditions for high-accuracy measurements.

Calibration Platform: Comprising silicon photodiode (350-1100m), InGaAs photodiode (900-1700nm) and diffuse reflector for optical fiber output (i.e. for spectrometer). Works together with our software in conjunction with Source Measure Units.
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.

We Are Trusted By Top-Scientists Worldwide
“We were pleased to discover that infinityPV offers a versatile industrial roll-to-roll coater which is capable of depositing functional materials via the slot-die coating technique. It offers very good control over various fabrication parameters, such as coating speed and temperature in addition to the possibility of choosing from different drying options (hot air and IR drying).” — Dr. Dimitar Kutsarov, Research Fellow
High-Resolution Mapping of Solar Cell Performance
Laser Beam Induced Current (LBIC) is a high-resolution technique that maps the local photocurrent of a solar cell using a focused laser beam. It reveals spatial variations in performance, helping identify defects, shunts, inactive regions, and coating non-uniformities—making it a powerful tool for improving device quality, reliability, and manufacturing control.
