69-584 50.0mm Dia. x 200.0mm FL; Plano-Convex Lens Laser V-Coat 980nm
This is a 69-584 Plano-Convex lens, a spherical lens with a diameter of 50.0mm and a focal length of 200.0mm, designed for use with a 980nm wavelength. The lens is sourced from the reputable vendor, Edmund Optics.
The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. The base shape of the lens is circular, and it features a Plano-Convex geometry, meaning one side is flat (Plano), and the other side is curved (Convex).
The lens has a thickness of 2mm at the edge and 196.66mm at the center. The effective focal length (EFL) is 200mm, and the radius of curvature (R1) is 103.36mm. The back focal length (BFL) is the same as the EFL, at 196.66mm. The lens does not have an inner or outer radius.
The lens is coated with Edmund Optics' Las V-Coat 980, a specialized coating designed for high-power laser applications. This coating ensures high transmission and low reflection at the 980nm wavelength, making it ideal for use in laser systems.
