The 48-673 is a UV-AR coated plano-convex lens, boasting a 9mm diameter and a 12mm focal length. This lens, sourced from Edmund Optics, is a spherical lens with a base shape of a circle. The lens's geometry includes a 1.66mm thickness at the edge, a 4mm thickness at the center, and an effective focal length (EFL) of 12mm. The front and back surfaces of the lens are coated with the EDM UV STD CURVE coating, optimized for the 250-425nm wavelength range. The lens material is fused silica, identified as mal-1965 in the material database. The lens's inner and outer radii are both zero, indicating a planar surface on the incident side and a curved surface on the exit side. With its impressive specifications and high-quality coating, this lens is an excellent choice for applications requiring UV light transmission and precise focusing.
