Application: Chemical Resistant Optical Fibers

Chemical Resistant Optical Fibers

  • Overview

In some applications, optical fiber is conveyed into the area where optical sensing is desired. The fluid to convey the fiber can be detrimental to the optical fiber coatings. Fibercore has suitable coatings to not only survive the conveyance of the fiber but also to withstand the residual chemical environment that remains after the operation. Pure silica core single and graded index pure core multimode polyimide coated fiber are ideally suited to harsh chemical environments. In addition, the single-mode fibers can have FBGs written into them as well and this area can be coated with chemically sensitive materials that will expand/contract in the presence of certain target chemicals. In this way, the fiber can become a distributed chemical sensor. FBGs and our pure silica core single mode polyimide coated fiber provide the components for this type of sensing.
