The LA4579-UV is a plano-convex lens made of UV fused silica, a material known for its excellent transparency in the ultraviolet (UV) range. This lens, sourced from Thorlabs, has a diameter of 1 inch (25.4 mm) and a focal length of 301.1 mm. The lens's geometry includes a thickness of 2 mm at the edge and 2.6 mm at the center.
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 by reducing surface reflections, thereby increasing the amount of light transmitted through the lens.
The LA4579-UV is a spherical lens, meaning it has a curved surface that is a portion of a sphere. The radius of curvature (r1) of the curved surface is 138 mm, and the back focal length (bfl) is 298.2 mm. The lens's effective focal length (efl) is 300 mm.
This lens is a versatile component suitable for various applications that require high-quality UV transmission and precise focusing capabilities. Its robust construction and reliable performance make it a popular choice among optical engineers and researchers.
