Description

art photonics FlexiRay® Fiber Cables for a broad Mid-Infrared spectral range 3 – 17μm based on Polycrystalline Infra-Red (PIR-) Fibers.  FlexiRay® cables are used in a wide range of applications including Mid-IR light delivery, spectroscopy, remote temperature sensing, etc. PIR-fiber cables are available with a variety of standard fiber diameters, with different connectors (SMA-905, FC/PC, and FC/APC), and several types of protective sheathing. Manufacturing technologies of art photonics assure precise fiber position inside the connector ferrule and a perfect surface quality of the fiber end. Before shipping, each fiber cable passes through the detailed Quality Control procedure.
