67-475-INK 9.0mm Dia. x 15.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-475-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 (NIR) spectrum, specifically between 750nm and 1550nm, as indicated by its NIR II coating.
The lens features a front and back coating of edm nir-ii std curve, which is standard for this type of lens. The lens's geometry includes a thickness edge of 1.36mm and a thickness center of 2.5mm. The effective focal length (EFL) is 12mm, and the radius of curvature (R1) is 9.42mm. The back focal length (BFL) is 10.6mm, and both the inner and outer radii are 0mm.
The lens is made from n-sf11 Schott, a material known for its excellent optical properties in the NIR spectrum. The lens is inked, which is a process that adds a dye to the lens to enhance contrast and make it more visible against different backgrounds.
This lens is currently 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/.
