description

The development of specialty fibers for the mid-infrared region has result in a core / clad Polycristalline Infra-Red (PIR) fibers.
These PIR fibers are non toxic, very flexible, transparent across a broad spectral region from 4µm to 18µm and capable of operating over the wide temperature range of -200°C up to +150°C.
They are manufactured in a core / clad structure of superior quality from a silver halide solid solution (AgCl:AgBr) using an innovative vacuum extrusion method.
They have by no aging effect compared to an alternative bare core fiber. 

   
 
 

applications

Flexible delivery system for CO and CO2 laser up to 50W
• Flexible IR imaging systems
• Remote non-contact pyrometry in the 100-600K range
• Fiber probes for IR spectroscopy.

cables specifications

For high laser power delivery applications a free standing fiber end standard cable is the best option.
For other utilisations patchcord design is suitable. In this case PIR-fibers are protected by a loose PEEK jacket to provide stiff, flexible and hermetic protection against mechanical, photo-induced and chemical damage over a wide temperature range (up to 150°C).

DIMENSIONS
Fibers     Jacket's inner/outer ø
400/500     750/1590µm
630/700     1400/3175µm
900/1000   1400/3175µm

Connector :   SMA with a special Ti-ferrule

End surface treatment
• Cutting : low cost, high performance
• Polishing : for special application, including AR-coating (on request)
• MART : for reduced reflection of high CO2 laser intensity (on request)
