Quartz, especially fused silica, is widely used in optical applications because of its unique properties. But do you know why fused silica is suitable as an important component for optical glass applications? Some excellent properties of fused silica determine its importance.
Fused silica transmits light from the UV to the IR spectrum. According to the wave band, quartz glass is divided into JGS1, JGS2, JGS3 (related to the OH group content in the material). JGS1 is UV grade quartz glass with high transmittance (about 93.5%) in the 180-2500nm wave band. JGS2 quartz glass is transparent in the 220-2500 nm wave band, with a transmittance of over 93.5%. JGS3 is an infrared grade quartz glass, which not only has a transmittance of more than 93.5% in the near-ultraviolet-visible light wave band (260-700nm), but also has a high transmittance in the 700-3500 nm wave band.
Quartz glass has a very small thermal expansion coefficient and can withstand severe temperature changes. Quartz glass is heated to about 1100 ℃, and it will not burst into normal temperature water.
The softening point temperature of quartz glass is about 1730°C, it can be used for a long time at 1100°C, and the maximum use temperature in a short time can reach 1450°C.
Except for hydrofluoric acid, quartz glass hardly reacts chemically with other acids, and its acid resistance is 30 times that of ceramics.
High chemical purity and excellent hardness.
Due to these excellent optical, mechanical and thermal properties, fused silica is widely used in all spectra.
