Chalcogenide IR-Fiber Cables

art photonics development of specialty fibers for the Mid-Infrared region has resulted in a unique product – Chalcogenide Infra-Red (CIR-) fibers. Based on chalcogenide glasses (As2S3) they transmit IR-radiation in the spectral gap between Silica fibers (0.2-2.4µm) and Polycrystalline InfraRed (PIR) fibers (4-18µm) in the range of 1.5 – 6µm

Our single- and multimode CIR fibers are drawn in core/clad structure with double polymer coating and characterized by a low optical loss.
