Description

The OPTOMAN PP-Al2O3-60.0-5.0-AR1004-AR1004 is a 60 mm diameter UV laser window manufactured from UV-grade sapphire for demanding 308 nm laser applications. Its 5 mm thick sapphire substrate combines excellent optical durability with high resistance to degradation in high-energy ultraviolet environments.

Both surfaces feature Ion Beam Sputtered (IBS) anti-reflection coatings optimized for 308 nm at normal incidence, with reflectance of ≤0.2% per surface and overall transmission above 98.5%. The window provides a clear aperture greater than 85%, MIL 20/10 surface quality, less than 10 arcsec wedge, and transmitted wavefront distortion of λ/6 PV at 633 nm.

Designed for precision UV optical systems, this sapphire window offers a combination of high transmission, dimensional stability, surface quality, and durability. Its robust substrate and IBS coating make it suitable for laser systems where reliable optical performance and resistance to repeated cleaning are important.
