Solar simulator usually used xenon-lamps or metal-halide lamps as the light source. These lamps could produce a spectrum similar to the sun's spectrum. The solar simulator had the characteristics of high spectral accuracy, stable radiance, light intensity correction, and light gate integration. It supports automatic light intensity control, output beam direction setting, spectral response data download and other functions. Solar simulator had a wide range of applications, including the research and testing of solar cells, the testing of optical properties of materials, and the measurement and monitoring of solar radiation.
