15mm Dia. x 60mm FL, NIR II Coated, Plano-Convex Lens

Product Details AR Coated to Provide <0.7% Reflection per Surface for 750 - 1550nm Precision Fused Silica Substrate Various Coating Options: Uncoated , MgF 2 , UV-AR , UV-VIS , VIS-EXT , VIS-NIR , VIS 0° , YAG-BBAR , and NIR I TECHSPEC UV Fused Silica Plano-Convex (PCX) Lenses NIR II 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 NIR II Coated feature industry leading diameter and centration specifications, making them ideal for integration into demanding imaging and targeting applications. These lenses are NIR II coated to increase their coating performance in the 750 to 1550nm range.
