This product is a plano-convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as 38-459-INK, boasts a diameter of 12.5mm and a focal length of 50.0mm, making it suitable for a wide range of optical applications.
The lens is constructed from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. 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 allows for efficient light concentration and minimal spherical aberration.
The lens's front and back surfaces are coated with EDMM Vis Ext, a broadband anti-reflection coating designed for the visible spectrum (350-700nm). This coating enhances the lens's transmission capabilities, reducing unwanted reflections and improving overall system performance.
The lens's geometry details include an edge thickness of 1.23mm and a center thickness of 2mm. The inner and outer radii are 0mm, indicating a uniform curvature. The lens's effective focal length (EFL) is 50mm, and the back focal length (BFL) is 48.68mm.
