Product Details

AR Coated to Provide <1.75% Reflectance per Surface for 400 - 700nm
Designed for 0° Angle of Incidence
Various PCX Coating Options: Uncoated, VIS 0°, VIS-NIR, NIR I, NIR II, VIS-EXT, and YAG-BBAR
Also Available Pre-Mounted in Engraved C-Mount Housings

TECHSPEC® MgF2 Coated Plano-Convex (PCX) Lenses have a positive focal length, making them ideal for collecting and focusing light in imaging applications. They are also useful in a variety of applications involving emitters, detectors, lasers, and fiber optics. TECHSPEC® MgF2 Coated Plano-Convex (PCX) Lenses are available in a wide variety of diameters and focal lengths. Identical designs of these PCX lenses are also offered uncoated or with broadband anti-reflective (BBAR) coatings, which include VIS 0°, VIS-NIR, NIR I, NIR II, VIS-EXT, and YAG-BBAR.
