48-818 12mm Dia. x 40mm FL UV-VIS Coated; UV Plano-Convex Lens UV-VIS 250-700nm
The 48-818 is a UV-VIS coated plano-convex lens, boasting a diameter of 12mm and a focal length of 40mm. This lens is sourced from the reputable vendor, Edmund Optics, and is available for purchase directly from their website, currently in stock.
The lens is constructed from fused silica, a material with the material ID of mal-1965. This material is known for its excellent transparency across a wide spectrum, making it ideal for UV-VIS applications, which typically fall within the wavelength range of 250-700nm.
The lens features a spherical shape, with a front surface coated with the standard EDMM UV-VIS coating curve. This coating enhances the lens's performance in the UV-VIS range, further expanding its utility in various applications. The back surface of the lens also features the same EDMM UV-VIS coating curve, ensuring optimal performance from both sides.
The lens's geometry is well-defined, with an edge thickness of 2.12mm and a center thickness of 3.13mm. The inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature. The lens's effective focal length (EFL) is 40mm, and the back focal length (BFL) is 37.85mm. The radius of curvature (R1) is 18.34mm.
