光学零件是光学仪器的重要组成部分,如果产生故障,就会降低成象质量,影响观测精度,严重的甚至无法使用。光学零件的故障,大致有以下几种。一、附着物现象:镜片上有斑点、纤维、金属屑、漆屑、油脂及污垢等。产生原因:1.温度剧烈变化使其内部的润滑或防尘脂溶化而流到镜片 Optical components are an important part of optical instruments. If a fault occurs, the image quality will be degraded, the accuracy of observation will be affected, and serious or even unusable. Optical parts of the failure, there are roughly the following. First, the attachment phenomena: lens spots, fibers, metal shavings, paint debris, grease and dirt. Reason: 1. The dramatic changes in temperature so that the internal lubrication or dust-free fat melt to the lens
