Mid IR 2.5 - 18 µm

Chalcogenide Mid-IR-Fiber Cables

Main features:

  • High transmittance in 1.1 – 6.5 μm range
  • Low optical losses 0.2 – 0.3 dB/m at 2.5 – 4 μm and 4.5 – 5 μm
  • Core/Clad structure with core diameters span from 8 to 500 μm
  • Temperature range -50°C + 90°C

For more information see data and downloads available below


art photonics offers FlexiRay® Fiber Cables for a Mid-Infrared spectral range 1.1 – 6.5 μm. Based on Chalcogenide Infra-Red (CIR-) fibers, FlexiRay® fiber cables are used in a wide range of applications including power delivery of QCL, spectroscopy, Flexible IR-imaging systems, etc. CIR- fiber cables are available with a variety of standard fiber diameters, SMA-905, FC/PC, FC/APC connectors, and several types of protective tubing. 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 detailed Quality Control procedure.
