Carbon coated high NA singlemode fiber

Acrylate coated
Hermetic coating
High NA
High temperature acrylate coated
Polyimide coated
Singlemode
Carbon high NA

Hermetic carbon protects the fiber from hydrogen and moisture.

These hermetic fibers are used in fiber optic sensors, avionics, and other demanding applications.
