49-241 9mm Dia. x 9mm FL; Uncoated; UV Double-Convex Lens
The 49-241 is a 9mm diameter, 9mm focal length uncoated UV double-convex lens, sourced from the reputable optical vendor, Edmund Optics. This lens is a spherical lens with a convex-convex base shape and a circular geometry, designed for use in a wide range of optical applications.
The lens's geometry features a thickness of 1.84mm at the edge and 4.9mm at the center, with an effective focal length (EFL) of 9mm. The first radius of curvature (R1) is 7.39mm, while the second radius (R2) is -7.39mm, and the back focal length (BFL) is 7.12mm. The lens's inner and outer radii are both 0mm, indicating a symmetrical design.
The lens is made from fused silica material, identified as 'fused sil mal-1965' in the material database. This material is known for its excellent transmittance in the ultraviolet (UV) region, making this lens particularly suitable for UV applications. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The wavelength for this lens is 587.6nm, which is in the visible light spectrum. However, due to its UV transmittance, it can be used in UV applications as well.
