38-338 12.0mm Dia. x 25mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 38-338 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 12.0mm diameter and a focal length of 25mm, making it suitable for a wide range of optical applications. The lens is made from N-BK7 Schott, a popular optical glass known for its excellent transparency and low dispersion.
The lens features a front and back coating of EDM NIR-I STD Curve, a specialized coating designed for use in the near-infrared spectrum, specifically between 600-1050nm. This coating enhances the lens's performance in the NIR range, improving its transmission and reducing reflection.
The geometry of the lens includes a thickness edge of 1.22mm and a thickness center of 2.7mm. The inner radius is 0mm, and the outer radius is also 0mm, indicating a plano surface on one side and a curved surface on the other. The radius of curvature (R1) is 12.92mm, and the back focal length (BFL) is 32.22mm.
The lens is currently in stock and available for purchase through the Edmund Optics website, as indicated by the "weblink status" field in the item data. This lens is a versatile and high-performing option for those requiring a Plano-Convex lens for use in the near-infrared spectrum.
