38-507 12.5mm Dia. x 40.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 38-507 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 12.5mm and a focal length of 40.0mm, making it suitable for a variety of applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a front and back coating of edm visnir0sp2002000, a VIS-NIR coating designed for use in the visible and near-infrared spectrum (400-1000nm). This coating enhances the lens's performance by reducing surface reflections and increasing transmission, making it ideal for use in systems where high light levels and low loss are critical.
The lens has a thickness of 1.23mm at the edge and 2.2mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a flat surface on the non-curved side of the lens. The lens's geometry also includes a 20.67mm radius of curvature (R1) and a back focal length of 38.55mm.
