69-463 50.0mm Dia. x 250.0mm FL; Plano-Convex Lens Laser V-Coat 633nm
This is a 69-463 Plano-Convex lens, a type of spherical lens, with a diameter of 50.0mm and a focal length of 250.0mm, specifically designed for use with a wavelength of 633nm. The lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. The lens has a planar surface on one side and a convex surface on the other, with a thickness of 2.5mm at the edge and 4.94mm at the center. The effective focal length (EFL) of the lens is 250.0mm, and the radius of curvature of the curved surface is 129.21mm. The back focal length (BFL) of the lens is 246.74mm.
The lens features a laser V-coat coating on both the front and back surfaces, specifically designed for use with a 633nm wavelength. This coating enhances the lens's performance by reducing surface reflections and improving transmission. The coating is applied using Edmund Optics' advanced V-coat technology, ensuring high-quality and durable performance.
