中文摘要：

分析了当前超精密光学镜片表面评定方法及其存在的不足,提出引用ISO 25178-2中规范的部分表面3D参数来表征精密光学镜片三维表面,找出光学镜片表面形貌与对应的光学性能存在的关系,并实现ISO对超精密光学镜片三维表面的评定。仿真实验表明：当光学镜片表面的高度服从高斯分布时,其评价光学系统性能的传递函数随着均方值的减小而增大。用实例说明ISO的部分三维参数对光学镜片三维表面可以很好地区分,利用新的综合评价方法评定光学镜片表面形貌具有一定的可行性。

英文摘要：

The shortcomings of current ultra precision optical lens surface assessment methods is analysed. The existing optical elements surface characterization methods is embarked, combining with the three-dimensional surface parameters in the ISO25178-2. The relationship between the surface topography of optical lens and the corresponding optical properties is found out. The evaluation of the 3D surface of ultra precision optical lenses using the standard ISO is realized. The simulation results show that when the surface of the optical lens is highly subjectef to Gauss distribution, the transfer function of the optical system performance is evaluated with the decrease of the mean square value. And the example results show that the characteristics can also be well distinguished by the three dimensional parameters, and it has certain feasibility to characterize the optical surface by the use of the new comprehensive evaluation method.
