Description

The OPTOMAN PP-UVFS-25.4-6.35-AR784-AR784 is a 25.4 mm diameter ultrafast optical window manufactured from UVFS (Corning 7980 0F) and designed for high-performance femtosecond and picosecond laser systems. Both surfaces feature IBS anti-reflective coatings with reflectance below 0.1% at 515 nm, providing efficient transmission for frequency-doubled Yb:YAG laser applications.

With a 6.35 mm thickness, greater than 90% clear aperture, 10-5 surface quality, and surface flatness better than λ/10 at 633 nm, this fused silica window is suited to demanding precision optical systems. Parallelism below 10 arcsec and an estimated laser-induced damage threshold above 0.25 J/cm² at 515 nm for 500 fs, 10 kHz pulses support applications involving high peak optical intensities.

The ultrafast window is engineered to maintain high transmission while minimizing dispersion-related effects, making it suitable for beam delivery, laser protection, and optical interfaces in advanced ultrafast photonics systems.
