65-509 6.0mm Dia. x 6.0mm FL; Plano-Convex Lens Laser V-Coat 785nm
The 65-509 is a Plano-Convex spherical lens, characterized by its 6.0mm diameter and 6.0mm focal length, specifically designed for use with a 785nm wavelength. This lens is sourced from the reputable optical vendor, Edmund Optics.
The lens is fabricated from n-sf11 Schott material, a high-index glass with excellent optical properties. The Plano-Convex geometry, where one side is flat and the other is curved, allows for efficient light collimation and focusing. The lens has a center thickness of 2.5mm and an edge thickness of 1.42mm, providing robustness and durability.
The lens features a front and back coating of Edmund Optics Las V-Coat 785, a specialized coating designed for laser applications at 785nm. This coating enhances the lens's performance by reducing surface reflections and improving transmission, making it ideal for laser systems.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a symmetrical curvature. The effective focal length (EFL) is 6mm, which is the distance from the lens's principal point to the focal point. The front radius of curvature (R1) is 4.71mm.
