69-364 50.0mm Dia. x 500.0mm FL; Plano-Convex Lens Laser V-Coat 405nm
The 69-364 is a Plano-Convex spherical lens, sourced from Edmund Optics, with a diameter of 50.0mm and a focal length of 500.0mm. This lens is designed for use with a wavelength of 405nm, making it suitable for applications such as laser systems.
The lens is made from n-BK7 Schott glass, a popular material due to its excellent optical properties and versatility. The front and back surfaces of the lens are coated with Edmund Optics' Las V-Coat 405, a coating specifically designed for use with lasers at the 405nm wavelength. This coating enhances the lens's performance by reducing surface reflections and improving transmission.
The lens's geometry includes a thickness of 3.79mm at the edge and 5.0mm at the center. The inner and outer radii are both 0, indicating a flat surface on the non-curved side of the lens. The radius of curvature on the curved side is 258.4mm, and the back focal length is 496.7mm.
The lens's information is available on the Edmund Optics website, where it is listed as in stock. This indicates that the lens is readily available for purchase and use in various applications.
