65-475 9.0mm Dia. x 18.0mm FL; Plano-Convex Lens Laser V-Coat 532nm
This is a 65-475 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens has a diameter of 9.0mm and a focal length of 18.0mm, 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. This material is particularly suitable for use in laser applications due to its low auto-fluorescence and high thermal stability.
The lens features a Plano-Convex geometry, with a spherical surface on one side and a flat surface on the other. The radius of curvature of the spherical surface is 9.32mm, and the lens has a central thickness of 2.41mm and an edge thickness of 1.25mm. The lens's effective focal length (EFL) is 18.0mm, and its back focal length (BFL) is 16.41mm.
The lens is coated with Edmund Optics' Laser V-Coat 532, a broadband anti-reflection coating designed for use with 532nm lasers. This coating provides high transmission and low reflectivity, ensuring optimal performance in laser applications.
