65-466 25.0mm Dia. x 75.0mm FL; Plano-Convex Lens Laser V-Coat 405nm
The 65-466 is a Plano-Convex spherical lens, characterized by its circular base shape and a diameter of 25.0mm. This lens is designed with a long focal length of 75.0mm, making it suitable for applications that require a tight focus or high magnification. The lens has a central thickness of 4.5mm and an edge thickness of 2.43mm, providing a robust structure for various optical setups.
The lens is made from the material n-BK7 Schott, a popular choice in the optical industry due to its excellent optical properties and high damage threshold. The lens's front and back surfaces are coated with Edmund Optics' Las V-Coat 405, a coating specifically designed for laser applications at a wavelength of 405nm. This coating enhances the lens's performance by reducing surface reflections and improving transmission, making it ideal for laser-based systems.
The item data also provides the back focal length (BFL) of the lens, which is 72mm, and the effective focal length (EFL), which is the same as the focal length at 75mm. The inner and outer radii are both 0, indicating a symmetrical lens design.
