Description
The OPTOMAN PP-UVFS-25.4-6.35-DM214-AR362 is a premium UV harmonic separator (dichroic mirror) designed for demanding ultrafast laser systems requiring efficient wavelength separation between the fourth harmonic (257 nm) and second harmonic (515 nm). Manufactured on a precision UV fused silica substrate using advanced Ion Beam Sputtering (IBS) coating technology, this optic delivers exceptional reflectivity at 257 nm while providing high transmission at 515 nm at a 45° angle of incidence.
Engineered for high-power femtosecond and picosecond laser applications, the mirror combines excellent laser-induced damage threshold (LIDT), extremely low absorption, outstanding optical durability, and enhanced operational lifetime exceeding 10,000 hours under optimized conditions. Its precision-polished substrate and high-performance dielectric coating make it an excellent choice for scientific research, laser micromachining, nonlinear optics, semiconductor processing, and advanced industrial laser platforms.
