69-450 25.0mm Dia. x 150.0mm FL; Plano-Convex Lens Laser V-Coat 633nm
This is a 25.0mm diameter, 150.0mm focal length plano-convex lens, specifically designed for use with a 633nm laser and featuring a V-coat from Edmund Optics. The lens is sourced from Edmund Optics, a reputable vendor in the optical industry, and is currently in stock.
The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The plano-convex geometry, where one side is flat and the other is curved, is commonly used in optical systems due to its simplicity and versatility. The lens has a center thickness of 3.5mm and an edge thickness of 2.49mm, providing a good balance between weight and optical performance.
The lens's effective focal length (EFL) is 150.0mm, which is the distance from the lens's principal point to the focal point. The back focal length (BFL) is 147.81mm, which is the distance from the lens's rear surface to the focal point. The radius of curvature (R1) of the curved surface is 77.55mm.
The lens features a V-coat on both the front and back surfaces, specifically designed for 633nm lasers. This coating enhances the lens's performance by reducing reflections and increasing transmission at the design wavelength. The coating is applied using Edmund Optics' Laser V-Coat technology, ensuring high-quality and durable performance.
