69-462 50.0mm Dia. x 200.0mm FL; Plano-Convex Lens Laser V-Coat 633nm
This is a 50.0mm diameter, 200.0mm focal length Plano-Convex lens, specifically designed for use with a 633nm laser and featuring a V-Coat. The lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock.
The lens is made from n-BK7 Schott material, a popular choice for its high refractive index and low dispersion. The Plano-Convex geometry, where one side is flat and the other is curved, is ideal for a variety of applications, particularly where a collimated beam is required.
The lens has a center thickness of 5.07mm and an edge thickness of 2mm. The front and back surfaces of the lens are coated with Edmund Optics' Las V-Coat 633, designed to enhance laser damage threshold and provide excellent transmission at the specified wavelength.
The lens's effective focal length (EFL) is 200mm, and the radius of curvature (R1) is 103.36mm. The back focal length (BFL) is 196.66mm. The lens does not have an inner or outer radius.
