ABSTRACT:
In an image conduit, an annular glass cylinder surrounding an imaging bundle is employed to act as an illumination conduit. The illumination conduit may be a single annular light guiding structure or it may be a multilayer structure or a ring of fibers optically separated from the imaging bundle. The illumination conduit may be provided with a layers of lower index cladding glass to confine the light in an intermediate core. Alternatively, the bottle cladding may be a reflective coating deposited on the outside of the bottle after drawing.
