    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 (As₂ S₃) 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.
    Features:

    • High transmittance from 1.5μm to 6μm
    • Optical losses 0.2 dB/m at 2 - 4 μm
    • Double polymer coating for high flexibility
    • Standard fiber diameters from 8 to 500µm

    Applications:

    • Flexible IR-imaging systems
    • Remote non-contact pyrometry in the 200-600K range
    • Fiber probes for remote process IR - spectroscopy
    • Fiber amplifiers and lasers
