69-621 25.0mm Dia. x 85.0mm FL; Plano-Convex Lens Laser V-Coat 1064nm
This 25.0mm diameter x 85.0mm focal length Plano-Convex lens, offered by Edmund Optics, is specifically designed for use with a 1064nm wavelength. The lens is made from n-BK7 Schott material, a popular choice for its high refractive index and low dispersion, making it ideal for a wide range of optical applications.
The lens features a Plano-Convex geometry, where one side is flat (Plano) and the other side is curved (Convex). This design allows for a high level of light concentration, making it suitable for use in laser systems. The lens has a center thickness of 4.3mm and an edge thickness of 2.48mm, providing a robust structure while maintaining a sleek profile.
The lens is coated with Edmund Optics' Las V-Coat 1064, a specialized coating designed to enhance the performance of the lens when used with a 1064nm laser. This coating helps to reduce reflection and increase transmission, improving the overall efficiency of the optical system.
The lens has an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature across the lens. The effective focal length (EFL) is 85mm, which is the distance from the lens to the point where the light rays converge.
