art photonics developed a volume production technology of the unique product – Polycrystalline InfraRed (PIR-) Core/Clad fibers – transparent over a broad spectral range 3 – 18 μm.

The highest performance PIR Core/Clad fibers are extruded with the core diameters span from 240 to 860 µm. Continuously improved extrusion process provides PIR-fibers with a superior optical quality and high mechanical strength.

Low optical losses without absorption peaks over the mentioned spectral range ensure a successful use of PIR-fibers in a broad range of applications.
