The 49-240 6mm Dia. x 12mm FL; Uncoated; UV Double-Convex Lens is a high-quality optical component sourced from Edmund Optics. This lens, with its spherical design, is a type of Spherical Lens (Convex-Convex) and features a base shape of Circular, making it suitable for a wide range of optical applications.
The lens has a diameter of 6mm and a thickness edge of 1.34mm, with a thickness center of 2.2mm. The effective focal length (EFL) is 12mm, providing a focused image at a reasonable distance. The first radius of curvature (R1) is 10.65mm, while the second radius of curvature (R2) is -10.65mm, indicating a double-convex design. The back focal length (BFL) is 11.23mm.
This lens is made from fused sil mal-1965, a material known for its optical clarity and durability. It is designed to work with a wavelength of 587.6nm. The lens does not have any coating, which means it is uncoated. This can be beneficial in certain applications where a natural, unaltered optical path is desired.
