48-307 25mm Dia. x 75.6mm FL; UV-AR Coated; UV Double-Convex Lens UV-AR 250-425nm
The 48-307 is a UV-AR coated, UV double-convex lens, boasting a 25mm diameter and a focal length of 75.6mm. This lens, sourced from the reputable vendor Edmund Optics, is a spherical lens with a convex-convex base shape and a circular geometry.
The lens's geometry is meticulously designed, with a thickness of 2.57mm at the edge and 4.87mm at the center. The effective focal length (EFL) is 75.6mm, while the back focal length (BFL) is 73.91mm. The first and second radii (R1 and R2) are 68.55mm and -68.55mm, respectively. The lens's inner and outer radii are both zero, indicating a uniform curvature.
The lens is constructed from fused silica, identified as material ID fused sil mal-1965 in the item data. This material is known for its excellent optical properties and durability. The lens is coated with a UV-AR coating on both the front and back surfaces, following the standard curve as specified by Edmund Optics. This coating enhances the lens's performance in the UV spectrum, specifically between 250 and 425nm.
