Description

technical field [0001] The invention relates to a space vehicle ground calibration technology, in particular to a divergent solar simulator optical system with a large spot diameter and high uniformity. Background technique [0002] As a ground device for testing the photovoltaic output characteristics of solar cells, the solar simulator can simulate the solar radiation characteristics, including irradiance, spectral matching, spot diameter, spot divergence angle and irradiation uniformity. [0003] According to different optical structures, it can be divided into collimating solar simulator and divergent solar simulator. The collimating solar simulator designs a collimating lens in the optical system, which can simulate highly uniform solar radiation with a small collimating angle, but the beam aperture is limited by the collimating lens aperture. There is no need to design a collimating lens in the optical system of the divergent solar simulator, and the beam aperture can...
