Optical element, in use process, even if dustless laboratory, also hard to avoid can produce dust, for this kind of coating components, can't simply assume casually wipe directly, otherwise it will scratch the surface of the membrane system, cause scratches, influence of laser transmission, change the formation distribution of laser, serious can lead to laser damage optical element! How to make effective dust removal ash? Method is as follows: 1; First of all need to use the high pressure oil free nitrogen blow the surface of the optical element; 2; Then optical lens paper, drop a few drops of high purity isopropyl alcohol or methanol, and then wiped gently on the surface of the optical element 3; Pay attention to wipe method, wipe not looped, toward the fixed method to clean!
