Description

The OPTOMAN PP-UVFS-25.4-6.35-DM241-AR422 is a precision ultrafast dichroic mirror engineered for efficient wavelength separation in high-performance femtosecond and picosecond laser systems. Featuring an ion beam sputtered (IBS) coating on a UV fused silica substrate, this optical component provides high reflection at 1020–1040 nm and high transmission at 970–980 nm with minimal dispersion effects.

Designed for demanding Yb-based laser applications, this harmonic separator delivers excellent optical durability, low group delay dispersion (GDD), and high laser-induced damage threshold (LIDT) performance, helping preserve ultrashort pulse characteristics during beam routing and harmonic management. The 25.4 mm diameter, 6.35 mm thick design makes it suitable for integration into compact and advanced ultrafast optical assemblies.
