Description

The OPTOMAN PCV-F125-UVFS-25.4-CT2.0-AR784-AR784 is a precision 25.4 mm diameter concave lens designed for ultrafast laser beam control at 515 nm. Manufactured from UV-grade fused silica (JGS1), this negative lens provides a -125 mm focal length and is optimized for demanding femtosecond and picosecond laser applications.

Both optical surfaces feature IBS anti-reflective coatings with less than 0.1% reflectance at 515 nm, helping minimize optical losses and unwanted back reflections. The lens combines high surface quality, low wavefront distortion, tight centration, and an estimated laser-induced damage threshold above 0.25 J/cm² for 500 fs pulses at 10 kHz.

Its optical design is particularly suited to the second harmonic wavelength of Yb ultrafast laser systems, where reliable beam expansion, divergence control, and high-intensity pulse handling are required.
