摘　　要：针对当前曲面菲涅尔透镜普遍存在的加工工艺复杂、面型精度难于控制、制作成本较高等问题,在研究非等厚型平板菲涅尔透镜设计方法的基础上,提出一种中心透镜为球面、外侧环带为倾斜面的等厚型平板菲涅尔透镜的设计方法,给出了具体的设计实例,并进行了建模和光学仿真,模拟结果表明:该菲涅尔透镜设计的光学效率达到90.7%。The curved Fresnel lenses are usually found problematic in application, such as high process complexity, difficulty in surface accuracy control, high production cost and so on. To avoid these problems, based on studies of unequal-thickness slab Fresnel lens design, we proipose a slab Fresnel lens design method that employs spherical center lens, inclined outer ring and equal-thickness surface. Specific design examples, as well as their computer optical simula- tion are given in this paper. Simulation result shows the optical efficiency of the Fresnel lens design achieves 90.7 %. This kind of design provides a reference for engineering applications of the Fresnel lens applied in high concentrating photovoltaic modules.
