48-712-INK 5.0mm Dia. x 12.0mm FL; NIR I; Inked; Plano-Convex Lens NIR I 600-1050nm
The 48-712-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 near-infrared (NIR) spectrum, specifically between 600-1050nm.
The lens features a front and back coating of edm nir-i std curve, which is Edmund Optics' standard curve for NIR applications. This coating enhances the lens' performance in the NIR spectrum, providing improved transmission and reduced reflection.
The lens has a thickness of 1.25mm at the edge and 1.77mm at the center. The effective focal length (EFL) of the lens is 12mm, making it suitable for applications that require a longer focal length. The lens's inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature.
The lens's base shape is circular, and its geometry is plano-convex, meaning one side is flat (plano), and the other side is curved (convex). The radius of curvature (R1) of the curved side is 6.22mm, and the back focal length (BFL) is 10.83mm.
This lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and high transmittance in the visible and NIR spectra. The lens is inked, which is a process that adds a marking or identification to the lens for tracking and inventory purposes.
