Fused silica glass has a high transmittance from ultraviolet to near-infrared (185nm-00nm), and has a high transmittance in the deep ultraviolet region, making it widely used in ultraviolet lasers. In addition, compared with ordinary optical glass, fused quartz glass has better uniformity and lower thermal expansion coefficient, making it particularly suitable for applications in the ultraviolet to near-infrared wavelength range, high-power lasers and imaging fields. Ecoptik can provide the best fused silica, if you want to know the fused silica price, please feel free to contact us.
Fused Silica Descriptions
As a major optical product material, the main characteristics of fused silica are:
High purity and corrosion resistance
High softening temperature, strong heat resistance
Low thermal expansion coefficient, thermal shock resistance
From the ultraviolet band to the infrared band have good light transmission performance
Strong radiation resistance
