Chalcogenide Infrared (CIR)

Chalcognide InfraRed (CIR) glasses are the best As2S3-based material for fibre optics in the range of 1.5 - 6 µm. CIR fibres transmit IR-radiation in the gap between silica fibres(0.2-2.4µm) and Polycrystaline InfraRed (PIR) fibres (4-18µm). CIR fibre is drawn in core/clad structure with double polymer coating and characterized by a low optical loss and high flexibility.

The innovative glass purification process provides the attenuation spectra free from the OH absorption at 3 µm and thus it enables CIR-fibre to be used for Er:YAG laser power delivery.

FEATURES:

  • high transmittance from 1.5 µm up to 6 µm
  • suitable for Er:YAG - laser power delivery
  • optical losses 0.2 dB/m at 2 - 4 µm
  • double polymer coating for high flexibility
  • durable cables with SMA-connectors

APPLICATIONS:

  • Flexible delivery for Er:YAG - laser
  • flexible IR-imaging systems
  • remote non-contact pyrometry in the 200-600K range
  • fibre probes for remote process IR - spectroscopy
