Choosing a good lens can greatly increase our work efficiency. The high-quality protective lens has a longer service life, a higher damage threshold of reflective slag, higher cutting efficiency, faster cutting speed, better cutting effect and smoother cutting edge. First of all, the raw material is the key, and then the coating, the quality of the coating is also a key factor in cutting efficiency. Let's take a look at the raw materials for protecting the lens. The raw materials of protective lenses are mainly divided into three types, namely quartz glass, K9 glass, and silicon glass. Among them, quartz glass has excellent stability and laser resistance, and is also a material generally recognized by the mainstream market. Quartz glass is a four-two single-component glass with superior physical and chemical properties, high-purity chemical stability, wide spectral transmission wavelength, thermal shock resistance, high temperature deformation resistance, radiation resistance, electrical insulation, etc. Compared with K9 and silica glass, quartz has significant advantages in terms of heat resistance, laser resistance and power withstand.
