69-316 6.0mm Dia. x 15.0mm FL; Plano-Convex Lens Laser V-Coat 405nm

This is a 6.0mm diameter, 15.0mm focal length Plano-Convex lens, specifically designed for use with a 405nm wavelength and featuring a Laser V-Coat from Edmund Optics. The lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock.

The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. The Plano-Convex geometry, where one side is flat and the other is curved, is ideal for collimating or focusing light. The lens has an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature.

The lens has a center thickness of 2mm and an edge thickness of 1.4mm, providing a robust structure. The effective focal length (EFL) is 15mm, which is the distance from the lens's principal point to the focal point when the lens is imaging an object at infinity. The radius of curvature (R1) is 7.75mm, which is the curvature of the convex surface. The back focal length (BFL) is 13.68mm, which is the distance from the lens's rear surface to its focal point.

The lens features a Laser V-Coat on both the front and back surfaces, specifically designed for 405nm. This coating enhances the lens's performance by reducing surface reflections and increasing transmission. The coating is from Edmund Optics' EDM series, known for its durability and high-performance characteristics.
