Thin Fused Silica Laser Windows

TECHSPEC® Thin Fused Silica Laser Windows

TECHSPEC® Thin Fused Silica Laser Windows

×
  • Thin 1mm Thickness
  • UV or IR Fused Silica Substrates
  • Low Loss Broadband IBS Anti-Reflection Coating

TECHSPEC® Thin Fused Silica Laser Windows are designed with a 1mm thickness and are available with UV or IR Fused Silica substrates. These thin windows are coated on both surfaces with an ion-beam sputtered (IBS) broadband anti-reflection (BBAR) coating, providing lower absorption losses and scatter than conventionally coated anti-reflection windows. TECHSPEC Thin Fused Silica Laser Windows are ideal for applications that require high-performance optical windows with a small form factor. Uncoated Thin Fused Silica Laser Window substrates are available to offer the flexibility of custom coatings to meet your application requirements; please contact us for more information.

IR Grade Fused silica differs from UV Grade Fused Silica by its reduced content of OH- ions, resulting in higher transmission throughout the NIR spectrum and reduction of transmission in the UV spectrum.
