Chalcogenide Mid-IR Fibers

Categories: , Tag:

Main features:

  • High transmittance in the range 1.1 – 6.5 μm
  • Low optical losses of about 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 340 μm
  • Double polymer coating for high flexibility

For more information see data and downloads available below.

Description

Chalcogenide As-S glass fiber transmits IR-radiation in the spectral range of 1.1 – 6.5μm. High performance CIR core/clad fiber are drawn with core diameters span from 8µm to 340µm.

Advanced drawing process with double polymer jacket provides a superior mechanical strength and high flexibility of CIR- fibers.

Low optical losses and small absorption peaks over the mentioned spectral range ensure a successful use of CIR-fiber for a wide range of applications.
