Description

The OPTOMAN PP-UVFS-12.7-3.0-DM214-AR362 is a premium UV harmonic separator dichroic mirror engineered for demanding ultraviolet laser systems. Manufactured on a high-quality UV fused silica substrate, this 12.7 mm optic utilizes advanced Ion Beam Sputtering (IBS) coating technology to deliver exceptional optical performance, long-term stability, and high laser damage resistance.

The coating is optimized to provide greater than 99.5% s-polarized reflection at 257 nm while maintaining less than 1% p-polarized reflection at 515 nm at a 45° angle of incidence, making it ideal for harmonic separation in ultrafast and high-power laser applications. Its enhanced lifetime coating design ensures reliable operation in industrial, scientific, and research environments where optical durability and consistent performance are critical.
