This is a Plano-Convex Lens, a type of spherical lens, sourced from the renowned optical vendor, Edmund Optics. The lens has a diameter of 25.0mm and a focal length of 40.0mm, making it suitable for a wide range of optical applications.
The lens is made from the high-quality material, n-BK7 Schott, which is known for its excellent optical properties. 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 1.39mm at the edge and 5.6mm at the center. The effective focal length (EFL) is 40.0mm, and the radius of curvature (R1) is 20.67mm. The back focal length (BFL) is also 40.0mm, and both the inner and outer radii are 0mm.
The lens is coated with Edmund Optics' Las V-Coat 1550, which is specifically designed for laser applications at a wavelength of 1550nm. This coating ensures high transmission and low reflection, making it ideal for use in laser systems.
