32-490 25mm Dia. x 25mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
This is a 25mm diameter, 25mm focal length double-convex lens, offered by the renowned optical vendor, Edmund Optics. The lens is made from n-SF5 Schott, a high-quality glass material known for its excellent optical properties.
The lens features a standard MgF2 coating on both the front and back surfaces, which is designed to enhance light transmission and reduce reflection, particularly within the 400-700nm wavelength range. This coating is part of Edmund Optics' standard curve, ensuring consistent performance across similar products.
The lens geometry includes a center thickness of 8mm and an edge thickness of 2.9mm. The front and back radii of curvature are 31.94mm and -31.94mm respectively, resulting in a back focal length of 22.47mm. The effective focal length is 25mm.
This lens is a versatile and high-performing option for a variety of optical applications, particularly those requiring a broad wavelength range and high light transmission. Its double-convex design and high-quality coating make it an excellent choice for applications such as imaging, beam shaping, and light collimation.
