67-472-INK 9.0mm Dia. x 9.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-472-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 750nm and 1550nm. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.
The lens features a front and back coating of EDM NIR-II STD CURVE, which is specifically designed for use in the NIR II spectrum. This coating enhances the lens's performance by reducing surface reflections and increasing transmission in the NIR II range.
The lens has a thickness of 1.48mm at the edge and 1.6mm at the center. The effective focal length (EFL) is 72mm, and the back focal length (BFL) is 70.97mm. The radius of curvature for the first surface (R1) is 37.22mm. The lens is inked, which is a process that adds a dye to the lens to make it more visible and easier to handle.
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/.
