干涉仪检具
本技术涉及一种用于球面镜片检测的干涉仪检具。
技术介绍
球面镜片亚斯/局部面精度是光学成像的重要指标,在镜片研磨完成后需使用干涉仪进行抽检,当不良比例超标时需对整批次产品进行全检确认,在干涉仪上检测时,需使用干涉仪检具进行定位。传统干涉仪检具采用圆周定位,即治具内孔稍大于镜片外径(通常为0.1-0.2mm)。这样的检具通用性差,镜片外径差异大于0.5mm时,定位效果差,易平移,亚斯成像位置偏移,同时,生产加工时,需针对不同型号镜片需更换不同型号检具,更换频率高,影响检查效率,检具数量多,也会造成生产管理的浪费和治工具成本的提高。
技术实现思路
本技术的目的是针对以上不足之处,提供了一种干涉仪检具。本技术解决技术问题所采用的方案是,一种干涉仪检具,包括圆台,圆台下中部设置定位插柱,圆台上中部设置立柱,圆台外周设置有限位槽,圆台、定位插柱、立柱同轴心,且直径依次递减,立柱上端设置镜片放置面,镜片放置面的左右两侧铣扁形成避让台阶面,避让台阶面位于定位面下方,定位面前面设置有定位块,定位块内侧 ...
