口径大于200毫米的良好平面镜,尽管它会在光学测量的许多方面做出重要贡献,给中等口径的平面镜的制造工作带来很大方便,但由于材料质量、设备条件、工艺水平和检验手段等方面的局限,使其制造工作变得复杂麻烦。本文就图1所示的大平面镜,谈谈它的加工和检验。在加工方面将着重介绍抛光盘的制 A good plane mirror with a diameter of more than 200 mm, although it will make an important contribution to many aspects of optical measurement, is very convenient for the manufacture of medium-size flat mirrors, but due to material quality, equipment conditions, craftsmanship and test methods The limitations of the area make it complicated and complicated to manufacture. This article on the large mirror shown in Figure 1, talk about its processing and testing. In processing will focus on polishing disc system
