Description

The OPTOMAN PP-UVFS-25.4-6.35-2AR40 is a precision UV fused silica optical window manufactured from Corning 7980 0F substrate and optimized for high-transmission 532 nm laser applications. With a 25.4 mm diameter and 6.35 mm thickness, this window provides excellent dimensional stability for demanding laser systems.

Both optical surfaces feature IBS anti-reflective coatings with less than 0.1% reflectance at 532 nm and 0° angle of incidence. The window combines 10-5 scratch-dig surface quality, λ/10 surface flatness, low transmitted wavefront distortion, and parallelism below 3 arcmin for precise beam transmission. Its 10 J/cm² LIDT at 532 nm further supports demanding pulsed-laser applications.
