9.0mm Dia. x -13.5 FL; UV-AR Coated; UV Plano-Concave Lens 250-425nm
This 9.0mm Dia. x -13.5 FL Plano-Concave Lens, offered by Edmund Optics, is a spherical lens designed for use in the ultraviolet (UV) spectrum, specifically between 250 and 425 nanometers. The lens is UV-AR coated, indicating that it has an anti-reflective coating that enhances its performance in the UV range. This coating is applied to both the front and back surfaces of the lens, ensuring optimal light transmission and minimal reflection.
The lens is made from fused silica, a material with a high transmission rate in the UV range. The base shape of the lens is circular, and it has a diameter of 9.0mm. The lens's thickness at the edge is 3.4mm, while its center thickness is 2.0mm. The effective focal length (EFL) of the lens is -13.5, and its front radius (R1) is -6.2. The back focal length (BFL) of the lens is -14.89.
The lens is designed for use at a wavelength of 587.6 nanometers. Its shape is spherical, and it does not have any inner or outer radii. The lens is in stock and available for immediate purchase through the provided web link.
