Infrared Fibers

These infrared (IR) fibers are convenient for guiding light from a sample to a monochromator or photodetector or from a monochromator to a sample. Two specific fiber types are offered, differing in core material and structure and jacket material to provide optimum IR light transmission performance within their respective wavelength regions.

Features

Excellent transmittance over the 2 to 6 µm and 4 to 18 µm infrared regions

These fibers are made of two different core materials. Chalcogenide (CIR) fibers exhibit high transmittance from 2 to 6 µm, and are characterized by low optical loss and high flexibility. Polycrystalline (PIR) fibers exhibit high transmittance from 4 to 18 µm. The internal core and cladding are designed to prevent light form leaking through the fiber, and has a high enough damage tolerance to withstand damage from sources as intense as a continuous-wave CO₂ laser. Chalcogenide IR fibers have a max operating temperature of 96˚C and Polycrystalline IR fibers have a max operating temperature of 120˚C.

Custom lengths available

As standard parts, these light guides are available in 1 m and 1.5 m lengths. Custom lengths can be supplied upon request. Contact Newport Sales for more information.
