Description

The OPTOMAN PP-UVFS-12.7-6.0-DM235 is a precision UV fused silica (UVFS) dichroic mirror engineered for reliable harmonic separation in high-power Nd:YAG laser systems. Featuring Ion Beam Sputtered (IBS) coatings with an enhanced lifetime design, this optical filter delivers stable long-term performance and increased laser-induced damage threshold (LIDT) for demanding nanosecond pulse applications.

Optimized for 45° angle of incidence, the mirror provides HRs >99.5% reflectance at 266 nm while efficiently transmitting 532 nm and 1064 nm wavelengths. The 12.7 mm diameter and λ/8 surface flatness ensure excellent beam quality preservation and accurate wavelength separation, making it ideal for UV harmonic generation setups, laser beam routing, scientific instrumentation, and industrial laser processing systems where durability and optical precision are critical.
