25mm Dia. x 500mm FL VIS-NIR Coated UV Double-Convex Lens from Edmund Optics
This optical lens, sourced from Edmund Optics, is a 25mm diameter, 500mm focal length, spherical lens with a convex-convex base shape and a circular cross-section. The lens is made from fused silica, specifically the material ID fused sil mal-1965, ensuring high-quality performance and durability.
The lens's geometry includes a thickness of 3.01mm at the edge and 3.35mm at the center, with an effective focal length (EFL) of 500mm. The first and second radii of curvature are 457.93mm and -457.93mm, respectively, and the back focal length (BFL) is 498.85mm. The inner and outer radii are both 0mm, indicating a symmetrical design.
The lens is coated with edm visnir0sp2002000 on both the front and back surfaces, making it suitable for use in the visible (VIS) and near-infrared (NIR) spectrum, specifically between 400nm and 1000nm. This coating enhances the lens's performance in these wavelength ranges, making it ideal for a variety of applications.
The item data provided does not include information about the lens's mount or any additional features, so these aspects cannot be commented on in this description. However, the detailed specifications provided should offer a comprehensive understanding of the lens's capabilities and suitability for various applications.
