长度测量工具：多面棱体 具有準确夹角的正棱柱形量规 (图1 钢质12面体 )。它的测量面具有良好的光学反射性能。测量面数一般为8﹑12﹑24和36等﹐最多可达72面。它常用於检定角度测量工具﹐例如光学分度头﹑迴转工作台﹑多齿分度台等﹐检定时﹐利用自準直仪读数(图2 用多面棱体和自準直仪检定光学迴转工作台 )。多面棱体是在20世纪40年代由英国的C.O.泰勒森设计的。一般採用轴承钢和氮化钢等製造﹐测量面是最后在钢面上研磨出来的﹔也有採用光学玻璃﹑石英等透明材料製造的﹐但在测量面上要镀膜以增强其反射性能。后来又出现周边上装有光学反射镜的组合式多面棱体。多面棱体各夹角的製造允许误差一般为 1～3﹐测量面的平面度误差在0.03～0.1微米以内。由於它具有封闭圆周角的特性﹐所以不需要与角度基準比较﹐而用两个自準直仪利用全组合法(见角度测量)测量和计算出各夹角的偏差值﹐在使用时加以修正﹐以得到更高的测量精度。多面棱体各夹角的检定误差一般小於±1﹐很準确的可以达到±0.3以内。
