69-619 25.0mm Dia. x 40.0mm FL; Plano-Convex Lens Laser V-Coat 1064nm

This 25.0mm diameter by 40.0mm 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 is curved (convex). This design allows for a longer focal length and a larger diameter, making it suitable for focusing or collimating light in various setups. The lens has a center thickness of 5.6mm and an edge thickness of 1.39mm, providing a robust structure while maintaining a relatively lightweight profile.

The lens is coated with Edmund Optics' Laser V-Coat 1064, a proprietary coating that enhances its performance in laser applications. This coating reduces reflection and increases transmission, ensuring optimal light propagation through the lens. The coating is applied to both the front and back surfaces of the lens, providing comprehensive protection and performance enhancement.
