The OPTOMAN PCV-F400-UVFS-25.4-CT2.0-AR548-AR548 is a 25.4 mm diameter plano-concave lens manufactured from UV-grade fused silica (JGS1) for precision beam expansion and divergence control in 1030 nm laser systems. Its −400 mm focal length provides controlled negative optical power, while the 20-10 surface quality and less than λ/6 surface irregularity support accurate wavefront performance.

Both optical surfaces feature an ion beam sputtered anti-reflection coating with reflectance below 0.1% at 1030 nm, helping reduce optical losses and unwanted reflections. The lens is designed for demanding ultrafast laser applications, with an estimated laser-induced damage threshold above 0.5 J/cm² at 1030 nm, 500 fs and 10 kHz. Its 25.4 mm format makes it suitable for integration into standard optical mounts and beam-conditioning assemblies.
