Visual Inspection

The following end-on pictures were taken of a scintillating fiber and a light guide segment under a microscope, after the ends have been polished using office paper. From these pictures, it is difficult to discern any difference between multi-clad fiber and single-clad. The scintillating fiber (light-green tint) is multi-clad, whereas the light guide in these photographs is single-cladding fiber.
