art photonics development of specialty fibers for the Mid-Infrared region has resulted in a unique product – Core / Clad Polycrystalline Infra-Red (PIR-) fibers, transparent over a broad spectral range –  4 -18 μm and capable for operating over the wide temperature band from 4K to 420K.

PIR fibers are used for a various applications: spectroscopy and process monitoring, IR radiation delivery to and from the hard-to-reach objects, thermosensing, CO-, CO₂ and QC-laser power delivery systems, IR-imaging and more.
