Description

The OPTOMAN PP-UVFS-25.4-6.35-LLM379EL is an enhanced lifetime ultrafast laser mirror designed for high-performance femtosecond and picosecond UV laser systems operating at 343 nm. Manufactured from UV fused silica (UVFS), this 25.4 mm diameter mirror combines high reflectivity, excellent surface quality, and advanced ion beam sputtering (IBS) coating technology to deliver reliable performance in demanding high-power laser environments.

Featuring optimized reflection performance at a 45° angle of incidence, the mirror provides HRs >99.7% and HRp >99.6% at 343 nm while maintaining low group delay dispersion (GDD) for ultrashort pulse applications. Its non-degrading coating technology is engineered for extended operational lifetime exceeding 10,000 hours, helping reduce maintenance requirements and system downtime in industrial laser applications.

The PP-UVFS-25.4-6.35-LLM379EL is suitable for advanced UV micromachining, glass processing, polymer structuring, and other production environments where optical stability and long-term durability are critical.
