48-296 25mm Dia. x 75.6mm FL; Uncoated; UV Double-Convex Lens

The 48-296 is a 25mm diameter, double-convex lens with a focal length of 75.6mm, sourced from Edmund Optics. This lens is uncoated and optimized for UV light, making it an ideal choice for applications that require high transmission in the ultraviolet spectrum.

The lens features a base shape of a circle, with an edge thickness of 2.57mm and a center thickness of 4.87mm. The effective focal length (EFL) is 75.6mm, and the back focal length (BFL) is 73.91mm. The first radius of curvature (R1) is 68.55mm, and the second radius of curvature (R2) is -68.55mm, indicating a strongly converging lens.

The lens is made of fused silica, a material with a high transmittance across a wide range of wavelengths, including the UV region. This makes the 48-296 particularly suitable for UV imaging, spectroscopy, and other applications where UV transparency is crucial.

Please note that the lens is uncoated, which may result in reduced transmission and increased susceptibility to environmental factors such as dust and moisture. However, uncoated lenses can offer superior optical performance in specific applications, making the 48-296 a versatile choice for a variety of UV-based optical systems.
