Glass Optical Window
From UV to VIS to IR wavelength, we have Fused Silica (WFS)/BK7 (WBK) optical windows, which are known for its low coefficient of thermal expansion, it has a high transmittance for light from ultraviolet to the near-infrared range, low scattering, and excellent cost-effectiveness. Coated Fused Silica windows are widely used in fiber laser cutting and welding systems.
Customization may be available for this product to suit your technical requirements. Let us know your required specifications.
