摘　　要：针对星载角锥棱镜光束平行差的特殊要求,以我国皮纳卫星激光测距合作目标中使用的通光口径为10mm角锥棱镜为例,介绍一种小口径角锥棱镜加工工艺:通过传统工艺加工出尺寸适中的角锥棱镜;通过配重分离器工艺实现光束平行差的精确控制;通过“大改小”工艺加工成小口径角锥棱镜,成品率可达83%;实践证明:该工艺可以克服小口径角锥棱镜光束平行差无法精确控制的问题,适合小口径星载角锥棱镜的加工。In view of the special requirements of the beam parallelism deviation of the Space-borne corner cube prism, a aperture of 10mm corner cube prism used in the Pina satellite laser ranging cooperation target is introduced as an example: Firstly, through the traditional process to process the moderate size of the corner cube prism;Then, the precise control of the beam parallelism deviation is realized through the Counterweight separator processing;Finally, the small-diameter corner cube prism is processed through the "big to small" process, The final product qualification rate can reach 83%.Practice has proved that this process can overcome the problem that the beam parallelism deviation cannot be accurately controlled and is suitable for the processing of small caliber star-borne angular cone prism.
