GB/T 7660.1-2013 in English

《GB/T 7660.1-2013反射棱镜 第1部分：几何特性》由TC103（全国光学和光子学标准化技术委员会）归口，主管部门为中国机械工业联合会。
GB/T7660的本部分规定了与反射棱镜几何特性相关的术语及定义和反射棱镜的分类、代号命名和图样标注的规则,同时给出了常用反射棱镜的外形简图、角度和尺寸关系式以及棱镜图样应标注的角度公差。
本部分适用于指导反射棱镜及其光学系统的设计和棱镜的制造、检验工作。

Scope

This part of GB/T 7660 stipulates the terms and definitions related to the geometric characteristics of reflective prisms and the rules for the classification, code naming and pattern labeling of reflective prisms. At the same time, the outline diagrams, angles and dimensions of commonly used reflective prisms are given. And the angular tolerance that should be marked on the prism pattern. This part is applicable to guide the design of reflective prisms and their optical systems, as well as the manufacture and inspection of prisms.
