88-634-INK 5.0mm Dia. x 20.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 88-634-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 5.0mm, is designed for use in the visible light spectrum, specifically between 350-700nm, making it suitable for a wide range of optical applications.
The lens features a front and back coating of EDmund Visible Extended (VIS-EXT), which is a broadband anti-reflection coating designed for high efficiency in the visible spectrum. This coating enhances the lens's performance by reducing surface reflections and increasing transmission.
The lens's geometry includes a thickness edge of 1.19mm and a thickness center of 1.5mm. The effective focal length (EFL) is 20mm, and the radius of curvature (R1) is 10.34mm. The back focal length (BFL) is 19.02mm, and the lens has no inner or outer radius, indicating a plano surface on the incident side.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. This lens is a versatile and high-performing component, ideal for applications requiring a small, high-quality lens with broadband anti-reflection coating.
