Abstract

In order to improve simulation precision of solar simulator, this paper researched general design scheme of optical system. First of all, this paper discussed optimization techniques for focusing system, optical integrator, collimating system, and which aberrations influenced the uniformity of optical integrator; Secondly, analysis of defocus effect for integrator projector lens and put forward optimal defocus distance formula, then using ZEMAX to design collimating optical system, and simulated the system in LightTools; Finally, tested solar simulator, the results show that: it can simulated one solar constant, irradiation range reached Φ200mm, working distance is 1000mm, irradiation non uniformity in 60mm range is less than ±1%, and in (60-200) mm is less than ± 2%, instability is better than ± 1%/h.
