The OPTOMAN PCV-F200-UVFS-25.4-CT2.0-AR784-AR784 is a 25.4 mm diameter concave lens manufactured from UVFS (JGS1) and designed for precision beam control in ultrafast laser systems. With a -200 mm focal length, the lens provides controlled beam divergence while maintaining high optical quality for demanding photonics applications.

Its IBS anti-reflective coating is optimized for 515 nm, with less than 0.1% reflectance at normal incidence on both surfaces. The lens features a 2.0 mm central thickness, greater than 80% clear aperture, 20-10 surface quality, and surface irregularity below λ/6 at 633 nm. Its estimated laser-induced damage threshold exceeds 0.25 J/cm² at 515 nm for 500 fs pulses at 10 kHz, making it suitable for femtosecond and picosecond laser applications where low optical loss and pulse preservation are important.
