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 50.0mm, designed for use with a wavelength of 1550nm.
The lens is made from the high-quality material, n-BK7 Schott, which is known for its excellent optical properties and durability. The base shape of the lens is circular, and it features a Plano-Convex geometry, where one side is flat (Plano) and the other side is curved (Convex).
The lens has a thickness of 1.68mm at the edge and 4.9mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a symmetrical curvature. The effective focal length (EFL) of the lens is 50mm, and the back focal length (BFL) is also 50mm.
The lens is coated with Edmund Optics' Las V-Coat 1550, a specialized coating designed for laser applications at 1550nm. This coating ensures high transmission and low reflection, making it ideal for use in laser systems.
