48-661-INK 5.0mm Dia. x 7.5mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 48-661-INK is a plano-convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 5.0mm, is designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically catering to wavelengths between 400 and 1000nm.
The lens features a front and back coating of edm visnir0sp2002000, which is a broadband anti-reflection coating optimized for the VIS-NIR range. This coating aids in minimizing surface reflections, thereby enhancing the overall transmission of light through the lens.
The lens's geometry includes a thickness of 1.34mm at the edge and 1.9mm at the center, with an effective focal length (EFL) of 7.5mm. The radius of curvature for the first surface (R1) is 5.89mm, while the back focal length (BFL) is 6.43mm. The lens is made from n-sf11 Schott, a high-index glass with excellent optical properties.
The lens is inked, a process that involves applying a dye or pigment to the surface of the lens. This can be useful for marking or identifying the lens, or for distinguishing between different lenses in a multi-lens system.
