65-450 6.0mm Dia. x 12.0mm FL; Plano-Convex Lens Laser V-Coat 405nm

This is a 65-450 Plano-Convex lens, designed with a 6.0mm diameter and a focal length of 12.0mm, specifically engineered for use with a 405nm wavelength. The lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock.

The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion. The plano-convex shape, where one side is flat and the other is curved, allows for efficient light transmission and focusing. The lens has a center thickness of 1.6mm and an edge thickness of 0.83mm, providing a robust structure while maintaining a sleek profile.

The lens features a V-coat coating on both the front and back surfaces, specifically designed for laser applications at 405nm. This coating enhances the lens's performance by reducing surface reflections and improving transmission, ensuring optimal laser operation.

The geometry of the lens includes an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature across the lens. The effective focal length (EFL) is 12mm, which is the distance from the lens's principal point to the focal point, where the light rays converge. The lens's back focal length (BFL) is 10.94mm, which is the distance from the lens's rear surface to its focal point.
