48-293 25mm Dia. x 25mm FL; Uncoated; UV Double-Convex Lens
The 48-293 is a 25mm diameter, 25mm focal length uncoated UV double-convex lens, available from Edmund Optics. This lens is a spherical lens with a convex-convex base shape and a circular geometry, making it suitable for a wide range of optical applications.
The lens has a diameter of 25mm, with a thickness at the edge of 2.68mm and a center thickness of 10.9mm. The effective focal length (EFL) is 25mm, and the first radius of curvature (R1) is 21.06mm, while the second radius of curvature (R2) is -21.06mm. The back focal length (BFL) is 20.93mm, and both the inner and outer radii are 0mm.
The lens is made from fused silica, identified as mal-1965 in the material ID. It is designed to operate at a wavelength of 587.6nm. The lens does not have any coating, which may affect its performance in certain applications. However, its uncoated status could make it more affordable and suitable for applications where coating is not necessary.
