LB4743-UV 5 mm Dia. UVFS Double-Convex Lens; EFL=10mm 245-400nm
The LB4743-UV is a 5 mm diameter Spherical Lens with a Double-Convex base shape and a UVFS material composition. This lens, sourced from Thorlabs, is designed for use in the ultraviolet spectrum, specifically between 245-400nm. The lens features an effective focal length (EFL) of 10mm, making it suitable for a variety of optical applications.
The lens geometry includes a 1.5mm thickness at the edge and a 2.2mm thickness at the center. The first radius of curvature (R1) is 8.8mm, while the second radius (R2) is -8.8mm, indicating a concave-convex shape. The lens does not have an inner or outer radius.
The LB4743-UV is coated with a UV-optimized broadband antireflection (UVBBAR) coating on both the front and back surfaces. This coating enhances the lens's performance in the UV range, reducing surface reflections and increasing transmission.
Please note that the lens is spherical in shape, which may introduce some spherical aberration. However, this is common in many optical systems and can often be corrected with additional optical elements or adjustments to the system design.
