2mm Dia. x 4mm FL UV-VIS Coated, UV Plano-Convex Lens

Product Details AR Coated to Provide <1.5% Reflection per Surface for 250 - 700nm Precision Fused Silica Substrate Various Coating Options: Uncoated , MgF 2 , UV-AR , VIS-EXT , VIS-NIR , VIS 0° , YAG-BBAR , NIR I , and NIR II TECHSPEC UV Fused Silica Plano-Convex (PCX) Lenses UV-VIS Coated 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). 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 UV-VIS Coated feature industry leading diameter and centration specifications, making them ideal for integration into demanding imaging and targeting applications. These lenses are UV-VIS coated to increase their coating performance in the ultraviolet and visible region.
