摘　　要：针对当前太阳模拟器辐照均匀性难以提高的问题,设计了一种新型集束式光学积分器。在对称式光学积分器理论分析的基础上,介绍了集束式光学积分器的设计过程,用Light Tools软件对太阳模拟器光学系统进行模拟仿真。结果表明,使用集束式光学积分器后,太阳模拟器不均匀度显著降低,在Φ50 mm范围内小于0.2%,Φ（50-120）mm范围内小于1.5%,满足高辐照均匀性的使用要求。In view of the difficulty in improving the irradiation uniformity of the current solar simulator, the pa- per introduces a new type of cluster-type optical integrator. The process of the cluster-type optical integrator based on the theoretical analysis of the symmetric optical integrator is introduced. The solar simulator optical system is simulated with LightTools software. The results show that： after using the cluster-type optical integra- tor, the irradiation non uniformity of solar simulator is significantly improved, irradiation non-uniformity in the range of -b 50 mm is less than 0.2%, and in the range of Φ （50-120） mm is less than 1.5%. The results satisfy the requirements of high irradiation uniformity.
