49-971 20mm Dia. x 30mm FL UV-VIS Coated; UV Plano-Convex Lens UV-VIS 250-700nm
The 49-971 is a UV-VIS coated Plano-Convex lens, boasting a diameter of 20mm and a focal length of 30mm. This lens is sourced from Edmund Optics, a reputable vendor known for its high-quality optical elements. The lens is designed for use within the UV-VIS spectrum, specifically between 250-700nm, making it suitable for a wide range of applications.
The lens is constructed from fused sil mal-1965, a material with well-established optical properties. It features a spherical shape, with a base shape of a circle. The geometry of the lens is defined by its diameter, thickness at the edge (1.69mm), and thickness at the center (6mm). The lens's effective focal length (EFL) is 30mm, and the radius of curvature (R1) is 13.75mm. The back focal length (BFL) is 25.88mm, and both the inner and outer radii are 0mm.
The 49-971 is coated with the EDM UV-VIS STD curve on both the front and back surfaces. This coating enhances the lens's performance within the UV-VIS spectrum, ensuring optimal transmission and minimal reflection. The lens's coating, combined with its high-quality material and precise geometry, make it a reliable and efficient choice for various optical applications.
