67-167-INK 25.0mm Dia. x 300.0mm FL; VIS 0deg; Inked; Plano-Convex Lens VIS 0° 425-675nm
This product is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as 67-167-INK, is a spherical lens with a base shape of a circle, designed for use within the visible light spectrum, specifically at a wavelength of 587.6nm.
The lens has a diameter of 25.0mm and a thickness at the edge of 2.5mm, while the center thickness measures 3.0mm. The effective focal length (EFL) of the lens is 300.0mm, and the radius of curvature (R1) is 155.04mm. The back focal length (BFL) is 298.02mm, and both the inner and outer radii are 0mm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens features a standard Vis-0 coating on both the front and back, designed to provide a broadband anti-reflection coating for visible light. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission.
The lens is inked, a process that adds a marking or identification to the lens. This can be useful for inventory management or to indicate the orientation of the lens.
