LA4130-UV UV Fused Silica Plano-Convex Lens; Dia:0.5 in; f=40.1 mm ARC 245-400nm
The LA4130-UV is a plano-convex lens made of UV fused silica, a material known for its excellent transparency in the ultraviolet (UV) region. This lens, sourced from Thorlabs, has a diameter of 0.5 inches (12.7 mm) and a focal length of 40.1 mm. The lens's geometry includes an edge thickness of 1.8 mm and a center thickness of 2.9 mm, with an effective focal length (EFL) of 40 mm.
The lens's front and back surfaces are coated with a UV anti-reflection coating, specifically designed for the 245-400 nm range. This coating enhances the lens's performance in UV applications by reducing surface reflections and increasing transmission.
The lens's base shape is circular, and its shape is spherical, which is common for plano-convex lenses. The inner and outer radii are both zero, indicating a sharp transition from the flat surface to the curved surface. The radius of curvature (R1) is 18.4 mm, and the back focal length (BFL) is 38 mm.
