摘　　要：锥体棱镜的设计要求一般为a≤5”，N=0．25，△N=O．2，是一种加工难度大，测量精度要求高的棱镜。采用对立方体加工形成锥体棱镜的制造方法，应用激光干涉测量技术对加工过程中的直角误差△90、棱镜的出射光与入射光的偏离角误差α进行测量与控制，是一种既能满足设计指标要求又能满足大批量生产要求的加工方法。该加工方法适合于入射面圆直径在鳓Ф50mm～Ф80mm的锥体棱镜。General requirements for the pyramid prisms design is α≤5＂, N= 0. 25, △N = O. 2. High machining dif ficulty and rigid measuring accuracy exists in the production of pyramid prisms. Pyramid prisms are manufactured from processing cubes. The right angle error during a processing and the deviation angle error between the outgoing light and the incident light are measured and controlled with laser interference measuring technology. The method can satisfy the demanded designing parameters and is propitious to the mass production. The processing method is suitable for massive production of pyramid prisms with incident diameter of 50-80mm.
