48-812 9mm Dia. x 27mm FL UV-VIS Coated; UV Plano-Convex Lens UV-VIS 250-700nm
The 48-812 is a UV-VIS coated Plano-Convex lens, boasting a diameter of 9mm and a focal length of 27mm. 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 catering to wavelengths between 250 and 700nm.
The lens is made from fused sil mal-1965, a material known for its optical clarity and durability. The front and back surfaces of the lens are coated with the standard EDMM UV-VIS coating, which enhances its performance within the specified wavelength range.
The geometry of the lens is characterized by its diameter, thickness at the edge (1.15mm), and thickness at the center (2mm). The lens's inner and outer radii are both zero, indicating a planar surface on one side and a curved surface on the other. The lens's effective focal length (EFL) is 27mm, and the radius of curvature (R1) is 12.38mm. The back focal length (BFL) is 25.63mm.
This lens is a Spherical Lens of the Sub Type Plano-Convex, and its base shape is Circular. It is a Spherical optical element, meaning it has a surface that is a part of a sphere. The Plano-Convex configuration refers to one flat surface and one curved surface, which focuses light onto a single point.
