Determine the maximum allowable deviation of the light source, and guide the adjustment of the spot according to the research results. The results show that the spatial location of the solar simulator light source is the key factor that affects the shape and energy distribution of the composite spot. It can provide reference for the design of the solar simulator light source adjustment system, spot data analysis and the determination of machining precision of key components.
