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...

Abstract

A method for cleaning optical glass comprises the steps that a first cleaning agent is formed, wherein the first cleaning agent is an acidic cleaning agent; the glass to be cleaned is provided; and the first cleaning agent is adopted for carrying out first wet cleaning treatment on the glass to be cleaned. According to the method for cleaning the optical glass, the first cleaning agent is adoptedfor carrying out first wet cleaning on the glass to be cleaned, the first cleaning agent is the acidic cleaning agent, the glass to be cleaned can be effectively cleaned, surface impurities of the glass to be cleaned are removed, and the surface of the glass to be cleaned can be prevented from being damaged. According to the method for cleaning the glass, the surface of the optical glass cannot bedamaged, secondary use of the optical glass cannot be influenced, and the service life of the optical glass can be prolonged.

Description

technical field [0001] The invention relates to the field of glass, in particular to a cleaning method for optical glass. Background technique [0002] Optical glass is the foundation and an important part of the optoelectronic technology industry. Especially after the 1990s, with the continuous integration of optics, electronic information science, and new material science, the application of optical glass as the basic material of optoelectronics in the three major fields of optical transmission, optical storage, and optoelectronic display has advanced by leaps and bounds. Social informatization, especially one of the basic conditions for the development of optoelectronic information technology. [0003] Optical glass refers to the glass that adds photosensitive materials to the glass, so that the glass can change the direction of light propagation and change the relative spectral distribution of ultraviolet, visible or infrared light. Optical glass can be used to manufac...
