4.5mm Diameter x 9.0mm FL Plano-Convex Lens with Visible Light Coating from Edmund Optics
This item is a 4.5mm diameter x 9.0mm focal length plano-convex lens, designed for use with visible light. It is sourced from the reputable optical components vendor, Edmund Optics. The lens is made from the high-quality material, n-BK7 Schott, which is known for its excellent optical properties and durability.
The lens features a plano-convex geometry, meaning one side is flat (plano) and the other side is curved (convex). This design allows for efficient light concentration and minimal spherical aberration. The lens has a diameter of 4.5mm and a thickness of 1.8mm at the edge, increasing to 2.38mm at the center. The effective focal length (EFL) is 9mm, and the radius of curvature (R1) is 4.65mm. The back focal length (BFL) is 7.41mm.
The lens is coated with a standard visible light coating (VIS 0°) on both the front and back surfaces. This coating enhances the lens's performance in the visible light spectrum, improving transmission and reducing reflection. The coating is designed to maintain a standard curve, ensuring consistent performance across a wide range of applications.
