- UV, Visible, and IR grade
- High Precision Applications
- Sizes Ranging from 5 to 220mm Diameters
- AR coating for laser lines and broadband
High precision Fused Silica Windows feature laser-grade surface quality (up to S/D 20/10) and parallelism up to 5 arc sec. In addition, these windows will limit flatness to 1/10λ.
Fused Silica windows available uncoated, or with anti-reflection coatings optimized for UV, visible or IR spectrum. Transmission characteristics and thermal properties make Fused Silica windows an excellent choice for most optical applications. Fused Silica windows are often used as vacuum viewports and sight glasses, mirror substrates, wedged windows and many other.
