45-470 6.0mm Dia. x 21.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 45-470 is a Plano-Convex lens, a type of spherical lens, with a diameter of 6.0mm and a focal length of 21.0mm. This lens is sourced from Edmund Optics, a reputable vendor in the optical industry. 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 VIS-NIR coating, specifically the EDM VISNIR0SP2002000 coating, on both the front and back surfaces. This coating is designed to enhance the lens' performance in the visible and near-infrared spectrum, specifically between 400 and 1000nm. The coating reduces surface reflections, thereby increasing transmission and improving overall image quality.
The geometry of the lens includes a thickness of 1.0mm at the edge and 1.42mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a flat surface on the uncoated side of the lens. The lens's effective focal length (EFL) is 21.0mm, and the back focal length (BFL) is 20.06mm. The radius of curvature (R1) is 10.85mm.
