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.
