Description

art photonics developed a volume production technology of a unique product – Core / Clad Polycrystalline Infra-Red (PIR-) fibers transparent over a broad spectral range 3 – 17 μm.

Highest performance PIR core/clad fiber are extruded with core diameters span from 240µm to 860µm. Continuously improved extrusion process provides a superior optical quality and mechanical strength of PIR- fibers.

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