LB4592 UV Fused Silica Bi-Convex Lens; Dia:2 in; f=60.0 mm Uncoated

The LB4592 is a high-quality bi-convex lens from Thorlabs, designed for use in a wide range of optical applications. This lens is made from UV fused silica, a material known for its excellent transmission properties across a broad spectrum, including the ultraviolet range.

The lens features a diameter of 2 inches (50.8 mm) and a focal length of 60.0 mm, making it suitable for use in systems where a longer focal length is required. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, this also makes it more cost-effective and suitable for applications where coating is not necessary.

The lens geometry includes a thickness of 2.5 mm at the edge and 15.6 mm at the center. The radii of curvature for the first and second surfaces are 52.6 mm and -52.6 mm, respectively. The back focal length is 54.4 mm, and the effective focal length is 60.0 mm. The lens does not have any inner or outer radius, indicating a uniform thickness across the lens.

This lens is a spherical lens with a convex-convex base shape and a circular geometry. It is part of the UVFS-1965 material category, which further highlights its suitability for ultraviolet applications. The lens is designed to work with a wavelength of 588 nm, making it a versatile option for various optical setups.
