This is a 65-547 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens has a diameter of 25.0mm and a focal length of 100.0mm, 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 and high damage threshold. 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 2.77mm at the edge and 4.3mm at the center. The effective focal length (EFL) is 100mm, and the radius of curvature (R1) is 51.68mm. The back focal length (BFL) is 97.17mm, and both the inner and outer radii are 0mm.
The lens is coated with Edmund Optics' Laser V-Coat 1064, a broadband anti-reflection coating designed for use with 1064nm lasers. This coating provides high transmission and low reflection, enhancing the lens' performance in laser applications.
