This is a 25.0mm diameter, 125.0mm focal length Plano-Convex lens, specifically designed for use with a 532nm wavelength. 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 base shape of the lens is circular, and it features a Plano-Convex geometry, where one side is flat, and the other side is curved. This geometry is often used to focus or collimate light in various optical systems.
The lens has a center thickness of 3.5mm and an edge thickness of 2.28mm. The effective focal length (EFL) is 125mm, and the radius of curvature (R1) is 64.62mm. The back focal length (BFL) is 122.7mm, and both the inner and outer radii are 0mm.
The lens is coated with Edmund Optics' Las V-Coat 532, a specialized coating designed for use with 532nm lasers. This coating enhances the lens's performance by reducing surface reflections and increasing transmission.
