LD4797-UV 6 mm Dia. UVFS Double-Concave Lens; EFL=-6mm 245-400nm
The LD4797-UV is a spherical lens with a base shape of a circle, sourced from the reputable vendor Thorlabs. This lens falls under the category of a Spherical Lens (Concave-Concave) and is designed for use in the ultraviolet (UV) spectrum, specifically at a wavelength of 588nm.
The lens has a diameter of 6mm and a center thickness of 2.5mm. The effective focal length (EFL) is -6mm, indicating that it is a double-concave lens. The first radius of curvature (R1) is -5.9mm, and the second radius of curvature (R2) is 5.9mm. The inner and outer radii are both 0mm.
The lens is made from UVFS material with the ID 1965. It features a UV-enhanced broadband anti-reflection (UVBBAR) coating on both the front and back surfaces, which is denoted as "tho uvfs uv bbar". This coating is designed to improve transmission and reduce reflection across the UV spectrum.
The lens is currently in stock and available for immediate purchase through the vendor's website, with the weblink provided in the item data.
