65-490 6.0mm Dia. x 12.0mm FL; Plano-Convex Lens Laser V-Coat 633nm
This is a 65-490 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens has a diameter of 6.0mm and a focal length of 12.0mm, making it suitable for a wide range of applications.
The lens is made from n-BK7 Schott, a popular optical glass known for its excellent optical properties. The base shape of the lens is circular, and it features a Plano-Convex geometry, which means one side is flat (Plano) and the other side is curved (Convex).
The lens has a thickness of 0.83mm at the edge and 1.6mm at the center. The effective focal length (EFL) is 12mm, and the radius of curvature (R1) is 6.2mm. The back focal length (BFL) is 10.94mm, and both the inner and outer radii are 0mm.
The lens is coated with Edmund Optics' Las V-Coat 633, a specialized coating designed for laser applications at a wavelength of 633nm. This coating ensures high transmission and low reflection, making it ideal for use in laser systems.
