This 69-369 optical lens, sourced from Edmund Optics, is a 6.0mm diameter Plano-Convex spherical lens with a 48.0mm focal length, specifically designed for use with a 532nm wavelength. The lens is made from n-BK7 Schott material, a popular choice for its high refractive index and low dispersion, making it ideal for a wide range of optical applications.
The lens features a front and back coating of Edmund Optics Las V-Coat 532, a proprietary coating designed to enhance laser damage threshold and provide excellent transmission at the specified wavelength. The lens has a center thickness of 1.6mm and an edge thickness of 1.42mm, with an effective focal length (EFL) of 48mm. The inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature.
The lens's geometry is circular, and its base shape is Plano-Convex, meaning one side is flat (Plano), and the other side is curved (Convex). The radius of curvature (R1) is 24.81mm, and the back focal length (BFL) is 46.95mm. This lens is currently in stock and available for immediate shipping.
