38-501 12.5mm Dia. x 17.5mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 38-501 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. It boasts a 12.5mm diameter and a focal length of 17.5mm, 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 transmittance and low auto-fluorescence.
The lens features a plano-convex geometry, meaning one side is flat (plano) and the other is curved (convex). The radius of curvature of the convex side is 9.05mm, and the lens has a central thickness of 3.8mm and an edge thickness of 1.29mm. The back focal length (BFL) is 15mm, and the effective focal length (EFL) is the same as the focal length, at 17.5mm.
The 38-501 is coated with edm visnir0sp2002000 on both the front and back surfaces. This coating enhances its performance in the visible (VIS) and near-infrared (NIR) spectrum, specifically between 400 and 1000nm.
