LB4710-UV 50.8 mm Dia. UVFS Double-Convex Lens; EFL=300mm 245-400nm

The LB4710-UV is a high-quality double-convex lens, boasting a diameter of 50.8 mm and a focal length of 300 mm, specifically designed for use in the ultraviolet spectrum, between 245-400 nm. This lens is sourced from the reputable optical components manufacturer, Thorlabs, and is readily available for purchase, as indicated by its "in stock" status on the vendor's website.

The lens is constructed from UVFS, a material with a refractive index well-suited for ultraviolet applications. It features a front and back coating of THo UVFS UV BAR, a proprietary broadband antireflection coating that further enhances its performance in the UV range. The lens's geometry is characterized by its edge thickness of 3 mm and center thickness of 5.4 mm, while its inner and outer radii are 0 mm, indicating a purely spherical design.

The LB4710-UV's radii of curvature are R1 = 275.2 mm and R2 = -275.2 mm, suggesting a strong focusing capability. The lens's shape is spherical, and its base shape is circular, making it compatible with a wide range of optical systems and applications.
