69-422 9.0mm Dia. x 12.0mm FL; Plano-Convex Lens Laser V-Coat 633nm
This is a 69-422 Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. The lens has a 9.0mm diameter and a 12.0mm focal length (FL), making it suitable for a variety of optical applications. The lens is made from n-sf11 Schott material, a high index glass with excellent transmittance in the visible and near-infrared regions.
The lens features a Plano-Convex geometry, meaning one side is flat (Plano) and the other side is curved (Convex). The curvature of the convex side is defined by a radius of 9.42mm. The lens has a central thickness of 2.5mm and an edge thickness of 1.36mm, providing structural integrity and minimizing optical aberrations.
The lens is coated with Edmund Optics' Las V-Coat 633, a broadband anti-reflection coating designed for use at a wavelength of 633nm. This coating reduces surface reflections, enhancing the transmission of light through the lens. The coating is applied to both the front and back surfaces of the lens.
