[0002] Optical glass includes colorless optical glass, colored optical glass, radiation-resistant optical glass, radiation-proof glass and optical quartz glass, etc. Optical glass is the foundation and an important part of the optoelectronic technology industry. In actual use, in order to reduce the wear of glass lenses caused by use, and in order to meet special use requirements, it is generally necessary to coat the surface of optical glass.

[0003] However, the functions of most coating devices used in optical glass manufacturing are relatively simple. In actual coating manufacturing, the optical glass will come into contact with dust in the air, and the surface of the optical glass will be stained with dust. When the optical glass is undergoing coating operation, the dust on the surface of the optical glass will cause poor coating uniformity, thereby affecting the coating quality of the optical glass. Utility Model Content
