LD4014-UV 9 mm Dia. UVFS Double-Concave Lens; EFL=-18.1mm 245-400nm
The LD4014-UV is a double-concave lens with a 9 mm diameter, designed for use in ultraviolet (UV) applications. This lens is sourced from Thorlabs, a reputable vendor known for its high-quality optical components. The lens is made from UVFS material, specifically identified as UVFS Mal-1965, which is well-suited for UV applications due to its transparency in this spectral range.
The lens features a double-concave geometry, with radii of curvature of -17 mm and 17 mm for the front and back surfaces, respectively. This geometry results in a negative focal length of -18.1 mm, which is specified as the Effective Focal Length (EFL). The lens's thickness at the center is 3 mm.
The LD4014-UV lens comes with a broadband anti-reflection (BBAR) coating, specifically designed for the UV range (245-400 nm) on both the front and back surfaces. This coating reduces surface reflections, thereby improving transmission and overall performance in UV applications.
