Description

The OPTOMAN PP-UVFS-25.4-6.35-AR43-AR43 is a precision UV fused silica optical window designed for 355 nm ultraviolet laser systems. Manufactured from Corning 7980 0F substrate, this 25.4 mm diameter, 6.35 mm thick window combines excellent optical quality with an IBS anti-reflective coating on both surfaces.

The AR43 coating provides less than 0.1% reflectance at 355 nm at normal incidence, while the 10-5 scratch-dig finish, λ/10 surface flatness, low transmitted wavefront distortion, and parallelism below 3 arcmin support accurate UV beam transmission. With a specified LIDT of 7.5 J/cm² at 355 nm for 20 ns pulses, it is suitable for demanding third-harmonic Nd:YAG and other 355 nm laser applications.
