AR Coated to Provide <1.25% Reflectance per Surface for 400 - 1000nm
<0.25% Reflectance @ 880nm
Designed for 0° Angle of Incidence
Various PCX Coating Options: Uncoated, MgF₂, VIS 0°, NIR I, NIR II, VIS-EXT, and YAG-BBAR

TECHSPEC® VIS-NIR 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. Plano-Convex lenses are ideal for a multitude of optics and photonics applications, including biotech instruments such as DNA sequencers and polymerase chain reaction (PCR) testing platforms. TECHSPEC® VIS-NIR 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 MgF2, VIS 0°, NIR I, NIR II, VIS-EXT, and YAG-BBAR.

These coated lenses are optimized for a wide range of optics and photonics applications, including biotech instruments such as DNA sequencers and polymerase chain reaction (PCR) testing platforms.
