LB4537-UV 6 mm Dia. UVFS Double-Convex Lens; EFL=15mm 245-400nm
The LB4537-UV is a 6 mm diameter double-convex lens, specifically designed for use in the ultraviolet (UV) spectrum. This lens, sourced from Thorlabs, features an effective focal length (EFL) of 15mm and is optimized for use within the wavelength range of 245-400nm.
The lens is constructed from UVFS, a material with a refractive index well-suited for UV applications. The base shape of the lens is circular, with a thickness of 1.5mm at the edge and 2.2mm at the center. The lens's geometry, including its 13.4mm radii of curvature for both the front and back surfaces, contributes to its excellent optical performance.
The LB4537-UV lens is equipped with a UV-enhanced broadband anti-reflection (BBAR) coating on both the front and back surfaces. This coating, designated as "tho uvfs uv bbar," is specifically designed to minimize surface reflections and increase transmission within the UV range.
This lens is a spherical lens, meaning it has a surface that is a portion of a sphere. The curvature of the lens allows for efficient light bending, making it ideal for a wide range of UV applications.
