Exail offers coreless fibers made of high-purity silica. Coreless fibers are pure silica glass rods with an acrylate coating for example used to terminate fiber end faces, either to reduce the power density, reduce back reflections, or manufacture micro-optics.
In the case of micro-structured photonic crystal fibers, coreless fibers are used to seal and protect the microstructure.
Exail’s coreless fibers use high purity silica optimized for transmission in the NIR, silica optimized for transmission in the UV or visible is available upon request.
