48-018 25.4mm Dia. x 63.5mm FL; Uncoated; CaF2 Double-Convex Lens
The 48-018 is a high-quality double-convex lens, boasting a 25.4mm diameter and a focal length of 63.5mm. This lens is sourced from the reputable vendor, Edmund Optics, and is available for immediate purchase. The lens is made from Calcium Fluoride (CaF2), a material with a Mal-1963 Material ID, which is known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum.
The lens features a base shape of a circle, with a geometry that includes an inner radius of 0 and an outer radius of 0. The thickness at the edge of the lens is 2mm, while the thickness at the center is 5.3mm. The effective focal length (EFL) is 63.5mm, and the back focal length (BFL) is 61.56mm. The first radius of curvature (R1) is 49.89mm, and the second radius of curvature (R2) is -49.89mm.
Notably, this lens does not come with any coating, making it suitable for applications where coating is not required or desirable. The lens is designed to work with a wavelength of 5000nm. Its spherical shape and double-convex design make it suitable for a wide range of optical applications.
