本文件规定了ISO 10110系列中非球面和具有低阶对称性的表面（如圆柱和圆环）的表示规则，该系列标准化了光学元件和系统的图纸指示。它还指定了符号约定和坐标系。 本文件不适用于离轴非球面和不连续表面，如菲涅耳表面或光栅。 注:对于离轴非球面和非对称表面，参见ISO 10110-19。 本文件未规定测试是否符合规范的方法。

This document specifies rules for presentation of aspheric surfaces and surfaces with low order symmetry such as cylinders and toroids in the ISO 10110 series, which standardizes drawing indications for optical elements and systems. It also specifies sign conventions and coordinate systems. This document does not apply to off-axis aspheric and discontinuous surfaces such as Fresnel surfaces or gratings. NOTE For off-axis aspheric and non-symmetric surfaces, see ISO 10110-19. This document does not specify the method by which conformity with the specifications is tested.
