Fused Silica

Name: Fused Silica
Brand: Ecoptik

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. As a professional fused silica manufacturer, Ecoptik can provide the best fused silica, if you want to know the fused silica price, please feel free to contact us.
