LA4936-UV UV Fused Silica Plano-Convex Lens; Dia:0.5 in; f=30.1 mm ARC 245-400nm
The LA4936-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 30.1 mm. The lens's geometry includes a thickness of 1.8 mm at the edge and 3.3 mm at the center, with an effective focal length (EFL) of 30 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 helps reduce surface reflections, thereby increasing the amount of light transmitted through the lens. The lens's shape is spherical, with a radius of curvature (R1) of 13.8 mm and a back focal length (BFL) of 27.7 mm.
This lens is an excellent choice for applications that require high-quality imaging in the UV region, such as UV microscopy, spectroscopy, and other UV-based optical systems. Its robust construction and high-performance coating make it a reliable component in various optical setups.
