Embodiment Construction
[0026] It can be known from the background art that the cleaning method of optical glass in the prior art has the problem of causing damage to the glass. Now combined with a cleaning method of optical glass to analyze the cause of its damage:
[0027] The shape of metal impurities is relatively stable, and it is difficult to remove them by general cleaning methods. Therefore, in the prior art, the dry method of scraping with sandpaper is often used to remove the volatile matter. However, the method of removing volatiles by scraping with sandpaper often causes damage to the surface of the optical glass, leaving scratches on the surface of the optical glass, which will affect the optical performance of the optical glass.
[0028] In addition, sandpaper scratches will also increase the surface roughness of the optical glass, thereby enhancing the surface adsorption capacity of the optical glass, resulting in the re-formation of impurities on the surface of the optical glass duri...
