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 60.0mm, 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 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 2.07mm at the edge and 4.7mm at the center. The effective focal length (EFL) is 60mm, and the radius of curvature (R1) is 31.01mm. The back focal length (BFL) is also 60mm, 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.
