45-478 9.0mm Dia. x 27.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
This 45-478 Plano-Convex Lens, sourced from Edmund Optics, is a spherical lens with a 9.0mm diameter and a focal length of 27.0mm. The lens is made from the high-quality material n-BK7 Schott, ensuring excellent optical performance. The lens's base shape is circular, and it features a plano-convex geometry, making it suitable for a wide range of applications.
The lens's geometry includes a thickness edge of 1.75mm and a thickness center of 2.5mm. The effective focal length (EFL) is 27.0mm, and the radius of curvature (R1) is 13.95mm. The back focal length (BFL) is 25.35mm, and both the inner and outer radii are 0mm.
The lens is coated with edm visnir0sp2002000 on both the front and back, making it suitable for use in the visible (VIS) and near-infrared (NIR) spectrum, specifically between 400-1000nm. This coating enhances the lens's performance in these wavelengths, providing superior transmission and reducing unwanted reflections.
The item data provided does not include information about the lens's clear aperture or its mounting thread, so these details are not included in the description. However, the lens's extensive specifications, high-quality material, and advanced coating make it a versatile and reliable choice for various optical applications.
