摘　　要：辐照强度均匀性是太阳模拟器的一项重要指标,采用光学积分器进行匀光具有设计复杂和成本高等问题。采用三维打印技术制备的模具,将超高效镜面反射片压制为微球面反射镜片,用两片微球面反射镜片和圆筒形光导管组成新型匀光器,利用光的漫反射原理,得到在150 mm直径光斑上的辐照强度不均匀性为1.12%,该结果达到IEC 60904-9的A级水平。新型匀光器具有结构简单、光源利用率高、造价低廉等特点。The uniformity of irradiance intensity is an important parameter of a solar simulator. There are some problems, such as designing complexity and high cost, in the process of using an optical integrator to obtain uniformity light. The microsphere surface reflective lens is pressed by the ultra-efficient mirror with the moulds prepared by three-dimensional printing technology. A new type of uniform light device is composed of two microsphere surface reflective lenses and a cylindrical light pipes. The non-uniformity of irradiance intensity of a light spot with a 150 mm diameter is 1.12% obtained by the principle of diffuse reflection of light. The result reaches the A level of IEC 60904-9. The new type of uniform light device has some characters such as simple structure, high utilization rate of light source, and low cost.
