Product Details

Low Cost Alternative to Silicon, ZnSe, and Germanium Lenses

Suitable for Applications in the 1650 – 2500nm Wavelength Range

Various Coating Options: Uncoated, MgF2, VIS 0°, VIS-NIR, NIR I, NIR II, VIS-EXT, and YAG-BBAR

TECHSPEC® SWIR Coated N-BK7 Plano-Convex (PCX) Lenses have a positive focal length, making them ideal for collecting and focusing light in imaging applications. Featuring an AR Coating designed to provide less than 0.1% reflection from 1650 – 3000nm, these lenses are ideal for applications utilizing InGaAs sensors with detection ranges up to 2500nm. TECHSPEC® SWIR Coated N-BK7 Plano-Convex (PCX) Lenses are a low cost, lightweight alternative to common infrared lenses manufactured from Silicon, Zinc Selenide, and Germanium substrates. Identical designs of these lenses are also offered uncoated or with broadband anti-reflective (BBAR) coatings, which include MgF2, VIS 0°, VIS-NIR, NIR I, NIR II, VIS-EXT, and YAG-BBAR. Note: While the coating is designed to provide low reflection out to 3000nm, N-BK7’s reduced transmission above 2200nm should be considered when integrating these lenses into sensitive applications.
