38-515 12.7mm Dia. x 20.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 38-515 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 12.7mm diameter and a 20.0mm focal length, making it suitable for a wide range 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 plano-convex geometry, meaning one side is flat (plano), and the other side is curved (convex). The radius of curvature of the curved surface is 10.34mm, and the back focal length is 17.49mm. The lens has a central thickness of 3.8mm and an edge thickness of 1.62mm, providing robustness and durability.
The 38-515 lens 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 400-1000nm. This makes the lens ideal for applications that require broadband light transmission, such as imaging, spectroscopy, and beam shaping.
