Description
The OPTOMAN PP-UVFS-50.8-9.52-LLM298 is a precision UV laser mirror designed for demanding ultraviolet laser systems operating between 343 nm and 355 nm. Manufactured on a high-quality UV fused silica (JGS1) substrate, this mirror features advanced Ion Beam Sputtered (IBS) coatings that provide exceptionally high reflectivity, low absorption, and outstanding long-term environmental stability.
Optimized for 45° angle of incidence, the mirror delivers HRs >99.9% and HRp >99.7% across the 343–355 nm wavelength range, making it an excellent choice for third-harmonic Nd:YAG and Yb:YAG laser applications. The precision-polished optical surface offers λ/10 flatness over a 30 mm aperture and 20-10 scratch-dig surface quality on the coated side, helping preserve beam quality while minimizing scattering. Built for high-average-power and high-repetition-rate laser systems, the PP-UVFS-50.8-9.52-LLM298 provides reliable performance in industrial, scientific, and OEM optical assemblies.
