88-621 3.0mm Dia. x 15.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-621 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a base shape of a circle and a diameter of 3mm, making it compact and versatile for various applications. The lens's thickness at the edge is 1.12mm, while the center thickness is slightly more at 1.26mm.
The effective focal length (EFL) of this lens is 15mm, which is the distance over which the lens's power is concentrated. The first radius of curvature (R1) is 7.78mm, and the back focal length (BFL) is 14.22mm. The lens does not have an inner or outer radius.
The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. This material is particularly suitable for applications in the visible spectrum, as indicated by the VIS-EXT coating on both the front and back of the lens. This coating enhances the lens's transmission in the extended visible spectrum, specifically between 350-700nm.
