摘　　要：球形透镜表面在一些高精度的光学系统变得越来越重要,它们和其他透镜表面一样必须满足一样的质量标准。本文采用数值计算方法分析了球形透镜的表面特性,并以Snell定律为基础,建立了用于计算球形表面特性的公式。通过与已有的球面特性公式进行比较,采用该方法计算球形透镜表面特性的拟合误差小于1μm。Spherical lens surfaces are more and more important in some high precision optical systems.They must conform to the same quality criteria of form and roughness as the other surfaces.In this paper,spherical lens surface profiles are analyzed using numerical method and the calculating formula of spherical lens surface profiles which is based Snell law has been derived.According to comparing with the reported formula,results indicate that the fitting error using this method is smaller than 1μm.

关 键 词：球形透镜 表面特性 拟合误差
