The hollow wave conduct fiber...
... or hollow waveguide fiber (HWG), is a flexible glass fiber with a hollow core for transmitting radiation in the mid-infrared range (2–18 µm) for beams with low divergence. Due to their flexibility, small diameter and low beam divergence compared to multimode infrared fibers, hollow waveguide fibers are a preferred tool for laser transmission. (HWG) fibers can be used in areas inaccessible to mirror arm laser systems or other technologies for industrial applications. The fibers are coated with a double polymer coating that offers high flexibility for various applications. Core sizes of 500 – 1000 µm are available.
