Image Fibers（Image Transmission）

Fujikura's image fiber is silica based coherent image fiber. Numbers of silica cores are together with melted silica cladding, which composes a multi-core optical fiber. Those fibers are used for the image transmission of fiber scopes applications. The products described in the catalog are for VIS region applications. Please contact us for customized products for UV or NIR region applications.
