48-781-INK 25.0mm Dia. x 750.0mm FL; NIR I; Inked; Plano-Convex Lens NIR I 600-1050nm
The 48-781-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 25.0mm, 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 3.0mm at the edge and 3.2mm at the center, with an effective focal length (EFL) of 750.0mm. The radius of curvature for the first surface (R1) is 387.6mm, and the back focal length (BFL) is 747.89mm. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number.
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 in applications where the lens may be misaligned or installed incorrectly.
The item data also indicates that this lens is in stock, making it readily available for immediate use. For more detailed information, including technical drawings and performance data, please refer to the vendor's website using the provided weblink.
