Description

The OPTOMAN PP-UVFS-25.4-3-DM74-AR116 is a premium ultrafast dichroic mirror engineered for efficient wavelength separation in femtosecond and picosecond laser systems. Manufactured on UV fused silica (Corning 7980 0F) and coated using advanced Ion Beam Sputtering (IBS) technology, this harmonic separator delivers exceptional optical performance with high laser damage resistance, low pulse dispersion, and excellent long-term stability.

Optimized for Yb:YAG laser platforms, the mirror reflects the second harmonic (505–535 nm) with greater than 99.5% efficiency while transmitting the fundamental wavelength (1000–1090 nm) with over 98% transmission at a 45° angle of incidence. Tight surface quality and wavefront specifications help preserve beam quality and ultrashort pulse duration, making this optic ideal for demanding industrial, scientific, and research applications.
