48-740-INK 12.0mm Dia. x 54.0mm FL; NIR I; Inked; Plano-Convex Lens NIR I 600-1050nm
The 48-740-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.0mm, 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, providing enhanced performance in the NIR range.
The lens has a thickness of 2.35mm at the edge and 3.0mm at the center, with an effective focal length (EFL) of 54.0mm. The radius of curvature for the first surface (R1) is 27.91mm, and the back focal length (BFL) is 52.02mm. The lens is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility.
The lens is inked, a process that involves applying a dye to the edge of the lens to indicate its orientation. This is particularly useful during assembly and can help prevent incorrect installation. The lens is available for purchase directly from the vendor's website, where it is currently listed as in stock.
