69-327 9.0mm Dia. x 90.0mm FL; Plano-Convex Lens Laser V-Coat 405nm
The 69-327 is a Plano-Convex spherical lens, characterized by its 9.0mm diameter and 90.0mm focal length, designed for use with a 405nm wavelength. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It features a Plano-Convex geometry, where one side is flat (Plano) and the other side is curved (Convex). This design is often used in optical systems to focus or collimate light.
The 69-327 lens has a center thickness of 2mm and an edge thickness of 1.78mm. The radius of curvature for the curved surface is 46.51mm, and the back focal length is 88.68mm. The lens has no inner or outer radius, indicating a uniform thickness across the lens.
The lens is coated with Edmund Optics' Las V-Coat 405, a specialized coating designed for laser applications at 405nm. This coating enhances the lens' performance by reducing surface reflections and improving transmission.
