摘　　要：介绍一种空心锥体棱镜加工工艺。首先,采用光学冷加工技术加工三个玻璃基板,并进行滚外圆和镀膜处理;其次,利用夹具初步固定三个基板,并在粘贴区域涂胶;最后,采用自准直平行光管对空心锥体棱镜的核心技术指标进行实时监测,紫外灯进行固化处理,控制成型。实践证明:该工艺可以对空心锥体的二面角进行精确控制,适合大口径空心锥体棱镜的加工。A machining process of hollow cone prism is introduced in this paper.The first is to use optical cold working technology to process the substrate of three glasses,and carry out external rolling and coating treatment.Next,fix the three substrates using fixtures,and then apply a layer of adhesive to the bonding area.Finally,the core technical indicators of the hollow cone prism are monitored in real time by self-collimating parallel light tube,and the UV lamp is cured to control the molding.Practice has proved that the process can accurately control the dihedral angle of hollow cone prism,which is suitable for the cool processing of large-diameter hollow cones.
