Description

The OPTOMAN PP-UVFS-25.4-3.0-DM131-AR260 is a precision ion beam sputtered (IBS) dichroic mirror engineered for efficient wavelength separation in high-power Yb:YAG and ytterbium fiber laser systems. Designed with a UV fused silica substrate (Corning 7980 0F), this optical component reflects the 976 nm pump wavelength while transmitting the 1030 nm laser wavelength at a 45° angle of incidence. Its advanced IBS coating technology delivers outstanding spectral stability, extremely low optical losses, high durability, and excellent long-term performance in demanding ultrafast laser environments.

With high reflectivity at 976 nm, high transmission at 1030 nm, superior surface quality, and tight manufacturing tolerances, this dichroic mirror is an excellent choice for pump combining, amplifier modules, intracavity beam routing, and other precision photonics applications where reliable wavelength management is critical.
