Description

The OPTOMAN PP-UVFS-12.7-6.35-DM430 is a premium dielectric dichroic mirror engineered for precise wavelength management in ultraviolet and visible laser systems. Fabricated from optical-grade UV fused silica and coated using advanced Ion Beam Sputtering (IBS) technology, it provides exceptional optical performance, environmental durability, and long-term stability.

Optimized for a 45° angle of incidence, the mirror delivers greater than 97.5% reflectivity at 266 nm while maintaining less than 2% p-polarized reflection at 532 nm and 1064 nm, making it ideal for harmonic separation, beam routing, and laser beam combining. Its precision-polished substrate, low-scatter coating, and resistance to thermal and environmental stress ensure consistent performance in scientific research, industrial laser systems, spectroscopy, and OEM photonics equipment where reliable wavelength discrimination is essential.
