For the classification of solar simulators the spectral irradiance is one relevant criterion. Array spectrometers are often used for this purpose. We developed a compact and portable spectrometer instrument specifically for flash and steady-state solar simulators. It is commercially available since 2011 under the name FlashSpec. Multiple experiments were performed to quantify several source of uncertainty. Among them were repeatability, temperature dependency, linearity and stray light. Straylight was investigated for a broad range of LEDs in combination with optical filters.
