88-674-INK 12.0mm Dia. x 20.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 88-674-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.0mm, is designed for use in the visible light spectrum, specifically between 350-700nm, making it suitable for a wide range of applications.
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. This coating helps to reduce surface reflections, thereby increasing the amount of light transmitted through the lens.
The geometry of the lens includes a thickness of 1.58mm at the edge and 3.5mm at the center, with an effective focal length (EFL) of 20mm. The radius of curvature for the first surface (R1) is 10.34mm, and the back focal length (BFL) is 22.15mm. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
This lens is a great choice for applications that require a broadband anti-reflection coating and a Plano-Convex lens design. It is currently in stock, as indicated by its weblink status.
