69-456 50.0mm Dia. x 50.0mm FL; Plano-Convex Lens Laser V-Coat 633nm
The 69-456 is a Plano-Convex spherical lens, boasting a 50.0mm diameter and a 50.0mm focal length. This lens is sourced from the reputable vendor, Edmund Optics, and is designed for use with a 633nm wavelength.
The lens is fabricated from n-sf11 Schott material, a popular choice for its high refractive index and low dispersion properties. The lens's geometry includes a 3mm edge thickness and a 12mm center thickness, contributing to its robust construction.
The 69-456 features a V-coat laser coating on both the front and back surfaces, specifically designed for 633nm. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving overall system efficiency.
The lens's base shape is circular, and its geometry is defined by a 39.24mm radius of curvature on the convex surface. The back surface is flat, and the lens has a 43.28mm back focal length. The lens does not have an inner or outer radius, indicating a uniform curvature.
