48-848 25mm Dia. x 150mm; UV-VIS Coated; UV Double-Convex Lens UV-VIS 250-700nm
The 48-848 is a UV-VIS coated, double-convex lens with a diameter of 25mm and a length of 150mm. This lens, sourced from Edmund Optics, is designed for use within the UV-VIS spectrum, specifically between 250-700nm.
The lens features a standard UV-VIS coating on both the front and back surfaces, adhering to the vendor's standard curve. This coating enhances the lens's performance within the UV-VIS spectrum, providing improved transmission and reduced reflection.
The lens's geometry is characterized by a thickness of 2.54mm at the edge and 3.68mm at the center. The effective focal length (EFL) is 150mm, and the radii of curvature are 136.96mm and -136.96mm for the first and second surfaces, respectively. The back focal length (BFL) is 148.37mm.
The lens is made from fused silica, identified as mal-1965 in the material database. This material is known for its excellent transparency across a wide range of wavelengths, making it an ideal choice for UV-VIS applications.
