  • In consideration of the defects of traditional condenser systems in low condensing rates, high costs and complex structures, high-power solar condensers were studied and designed. Based on the advantages of Cassegrain structure in high light gathering and beam coupling, a new type of high-power solar condenser was designed, and the optical design software ZEMAX was used to simulate the structure in different incident angles. The simulation results show that the Cassegrain structure eliminates the impact of spherical aberration. When arrival angle of sunshine is 0.5?, a concentration ratio of 544 and an optical efficiency of 84.835% can be obtained. Compared with traditional condenser systems, this device has a simple structure, high optical efficiency and a low cost. It has opened up a new path for the commercialization of solar condensers.
