45-892 25mm Dia. x 100mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 45-892 is a high-quality double-convex lens, boasting a 25mm diameter and a focal length of 100mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase on their official website. The product listing indicates that it is currently in stock, ensuring prompt delivery for interested buyers.
The lens is constructed from Schott's n-BK7 glass, a material well-known for its excellent optical properties. The base shape of the lens is circular, and it features a spherical geometry. The radius of curvature for the first surface is 103mm, while the second surface has a radius of -103mm, indicating its double-convex nature. The edge thickness of the lens is 2.48mm, and the center thickness is 4mm. The effective focal length (EFL) is 100mm, and the back focal length (BFL) is 98.95mm.
The lens is coated with a VIS-NIR coating, specifically the EDM VISNIR0SP2002000 coating, on both the front and back surfaces. This coating is designed to optimize performance in the visible and near-infrared spectrum, specifically between 400nm and 1000nm. This makes the lens suitable for a wide range of applications, including but not limited to, imaging, spectroscopy, and beam shaping in the aforementioned wavelength range.
