38-451-INK 12.5mm Dia. x 20mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 38-451-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.5mm, is designed for use in the visible light spectrum, specifically between 350-700nm. The lens features a front and back coating of edm vis ext, which is a broadband anti-reflection coating designed for high transmission in the visible spectrum.
The lens has a thickness of 1.4mm at the edge and 3.5mm at the center, with a focal length (EFL) of 20mm. The radius of curvature for the first surface (R1) is 10.34mm, and the back focal length (BFL) is 17.69mm. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
This lens is a great option for applications that require a broadband anti-reflection coating and operation within the visible spectrum. Its compact size and robust construction make it suitable for use in various settings. Please note that the lens is inked, which is a process used to mark lenses for identification and tracking purposes.
