多面棱镜棱体是一种高精度角度标准器具。它主要用于检定光学分度头、分度台、测角仪等圆分度仪器的分度误差，在高精度的机械加工中或测量中也可以作为角度的定位基准。
Polyhedral prism is a high-precision angle standard instrument. It is mainly used to verify the indexing error of circular indexing instruments such as optical indexing heads, indexing tables, and goniometers. It can also be used as a positioning reference for angles in highprecision machining or measurement
