LB4592-UV 50.8 mm Dia. UVFS Double-Convex Lens; EFL=60mm 245-400nm

The LB4592-UV is a high-quality double-convex lens, boasting a 50.8 mm diameter and a focal length of 60 mm, specifically designed for use within the ultraviolet spectrum, between 245-400 nm. This lens is sourced from the reputable optical vendor, Thorlabs, and is available directly from their website with a valid "in stock" status.

The lens features a spherical design, with both the front and back surfaces curvature defined by radii of 52.6 mm. The edge thickness of the lens measures 2.5 mm, while the center thickness is 15.6 mm, providing a robust and durable structure. The lens material is UVFS, a specialized material with a Mal-1965 index, ensuring optimal performance within the UV range.

The LB4592-UV lens comes equipped with a UV-optimized broadband anti-reflection (BBAR) coating on both the front and back surfaces, denoted as "tho uvfs uv bbar". This coating enhances transmission and reduces surface reflections, further optimizing the lens's performance within the UV spectrum.
