Buying Mid-infrared Fibers
Mid-infrared fibers are optical fibers designed for efficient transmission of mid-infrared light. These fibers can be made from materials such as chalcogenide glasses, germanate glasses, heavy metal fluoride glasses, sapphire, or polycrystalline substances, each offering unique properties for specific applications.

 Broad spectra fiber solutions art photonics GmbHRudower Chaussee 46 12489 Berlin Germany See us at LASER World of Photonics 2025 in Munich, June 24–27 (booth A3.218)! |  For the mid-IR spectral range, we produce
CIR fibers transmits infrared radiation in the spectral range of 1.1 μm – 6.5 μm. CIR- fibers with double polymer jacket provides a superior mechanical strength and high flexibility. Low optical losses ensure a successful use of CIR-fiber for a wide range of applications. PIR fibers are transparent over a broad spectral range 3 μm – 17 μm. Low optical losses without absorption peaks over the mentioned spectral range ensure a successful use of PIR fiber for a broad range of applications. The HWG design is a perfect option to transmit weakly divergent IR light in the mid IR range from 2 to 18 μm. High performance HWG are produced with double polymer jacket to secure a superior mechanical strength and high flexibility of HWGs. Product-specific web page |
