84-317 15mm Dia. x 25mm FL VIS-NIR Coated; UV Plano-Convex Lens VIS-NIR 400-1000nm
The 84-317 is a UV plano-convex lens, 15mm in diameter and 25mm in focal length, sourced from Edmund Optics. This lens is designed for use within the visible to near-infrared spectrum, specifically catering to wavelengths between 400 and 1000nm.
The lens is made from fused silica, a material with a high transmittance across a wide range of wavelengths, making it ideal for applications that require clarity and precision. The front and back surfaces of the lens are coated with a VIS-NIR coating, denoted as 'edm visnir0sp2002000'. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving overall image quality.
The lens's geometry is characterized by a 1.46mm edge thickness and a 4.25mm center thickness. The radius of curvature for the front surface is 11.46mm, and the back focal length is 22.09mm. The lens's shape is spherical, and it has no inner or outer radius, indicating a uniform curvature across the lens surface.
This lens is a spherical lens of the plano-convex type, meaning one surface is flat (plano), and the other is curved (convex). This design is often used in optical systems where a high level of focusing is required. The lens's base shape is circular, contributing to its wide field of view and making it suitable for a variety of applications.
