About Our Company
art photonics GmbH, founded in Berlin in September 1998, is one of the worldwide leaders in development and production of specialty fiber products for a broad spectrum from 300 nm to 16 µm. Unique technologies of Polycrystalline Mid InfraRed (PIR-) fibers and Metal coated Silica fibers are used for assembly of various spectroscopy probes for medical diagnostics and industrial process control, in volume production of fiber for medical and industrial lasers, for different fiber bundles, etc.
UV 200-400 nm
Near IR 750-2500 nm
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.
