Product Family Description

AR Coated to Provide <0.75% Reflection per Surface for 250 - 425nm
Precision Fused Silica Substrate
Various Coating Options: Uncoated, MgF₂, UV-VIS, VIS-EXT, VIS-NIR, VIS 0°, YAG-BBAR, NIR I, and NIR II

TECHSPEC® UV Fused Silica Plano-Convex (PCX) Lenses feature precision specifications and a variety of coating options on a broadband substrate. Fused Silica is commonly used in applications from the Ultraviolet (UV) through the Near-Infrared (NIR) and its low index of refraction, low coefficient of thermal expansion, and low inclusion content make it ideal for laser applications and harsh environmental conditions. TECHSPEC UV Fused Silica Plano-Convex (PCX) Lenses feature industry leading diameter and centration specifications, making them ideal for integration into demanding imaging and targeting applications.
