The reproduction of the solar spectrum with the highest possible accuracy is the most important feature of a solar simulator for testing the thermal design of components and sensors.

Testing the functionality and durability of components over a large temperature range in a vacuum simulates the space environment, including fast temperature changes, which can constitute a challenge for space instrumentation.

The IRF solar balance chamber hosts four metal halide light sources (Philips MSR 575 HR) for the reproduction of the solar flux. Metal halide sources are of advantage compared to Xe-arc lamps, because the latter contain large spikes in the IR-range in the spectrum.
