Fiberguide’s Polyimide Optical Fibers for High Temperature Performance

Coating protects fibers in extreme thermal conditions

Stirling, N.J. (December 3, 2009) – Providing optimal performance of fiber optics in extreme conditions, Fiberguide Industries offers a full line of standard optical fibers with polyimide coating.

Fiberguide's polyimide coated fibers for high temperature performance.

Fiberguide’s polyimide coating is ideal for oil and gas, aerospace, sensors, defense, medical and security applications requiring high temperature resistance.  The coating withstands operating temperatures up to 400ºC (300ºC continuous), while conventional coatings such as acrylate, nylon and Tefzel® begin to deteriorate between 100ºC and 250ºC.  

Additionally, Fiberguide’s unique process of applying the coating results in a fiber of significantly reduced cross-sectional area.  This low profile characteristic is optimal for use in bundles and supports spectral transmission from 160nm to 2500nm.

Polyimide coated fiber is available in step index, multimode fibers from 50um cores to 600um cores; 6.25um/125um and 50um//125um graded index; and 4.8um/125um and 9.2um/125um single mode fibers.  The fiber offers high performance optical and mechanical specifications with tight dimension tolerances providing high uniformity and lot-to-lot consistency.
