Product Family Description

Available Uncoated or with Broadband Anti-Reflection Coatings
Ideal for Cost Sensitive Broadband Applications
Sizes Ranging from 5mm to 100mm Diameter
λ/4 or λ/10 UV Fused Silica Windows Also Available

TECHSPEC® 1λ UV Fused Silica Windows are precision manufactured using UV-grade synthetic fused silica. In addition to superior transmission, the synthetic fused silica of these optical windows exhibit higher thermal properties, exceptional purity, and excellent environmental durability for demanding applications.

Note: New additions to this product family may be specified with a transmitted wavefront distortion (TWD) specification instead of a surface flatness. For more information on the difference between these two specifications, see our application note on Understanding Optical Windows.
