1λ UV Fused Silica Windows
• Available Uncoated or with Broadband
Anti-Reflection Coatings
• Sizes Ranging from 5 mm to 100 mm Diameter
• Ideal for Cost Sensitive Broadband Applications
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.
• High Transmission from 200 to 3500 nm
Infrared Fused Silica Windows provide high, flat transmission
across the visible and near-infrared spectra
and are available with Corning 7979 fused silica or
Suprasil® 300 substrates. These windows have a low
OH ion content, resulting in increased transmission
between 1400 - 2700 nm where UV fused silica (Corning
7980) experiences significant transmission losses
due to absorption. Infrared Fused Silica Windows are
ideal for laser material processing or medical laser applications
using Nd:doped or 2 micron lasers.
• λ/10 and λ/20 Surface Flatness Options
• Certified with a Zygo Interferometer
• Each λ/20 Flat Includes a Certificate of Calibration
