67-481-INK 9.0mm Dia. x 54.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-481-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 9.0mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750-1550nm. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent transparency in the visible and near-infrared regions.
The lens features a front and back coating of EDM NIR-II STD Curve, which is designed to enhance performance in the NIR II spectrum. The edge thickness of the lens is 1.75mm, while the center thickness is 2.3mm. The Effective Focal Length (EFL) of the lens is 36mm, and the Back Focal Length (BFL) is 34.48mm. The lens has an inner radius of 0mm and an outer radius of 0mm.
This lens is in stock and available for immediate purchase. For more information, please refer to the vendor's website at https://www.edmundoptics.com/f/nir-ii-coated-plano-convex-pcx-lenses/14105/.
