EyeSafe Delivery Fibers
Nufern has specifically engineered a unique range of single-mode 2μm beam delivery fibers for the long wavelength EyeSafe window from 1850-2200nm, available in both PM and non-PM versions. By applying extensive fiber manufacturing expertise, this family of fibers has excellent uniformity and high fatigue failure resistance. These fibers are aimed at emerging fiber applications for the 2μm wavelength, including medical, military/aerospace, and industrial fiber laser markets.
