ABSTRACT:
A flexible endoscopic probe includes a fiber optic image guide, a lens adhered to the distal end of the fiber optic image guide, and one or more fiber optic illumination fibers surrounding the image guide and terminating at the distal end of the probe. During manufacture, a mask tube is placed at least partially over the lens so that a masking material can be injected and cured. A retaining tube is disposed around the illumination fibers and a temporary tube is slid over the retaining tube so that a potting material can be injected into the spaces between the fibers, the image guide, and the retaining tube. The temporary tube is then removed, the distal end is ground and polished, and the masking material is removed from the lens.
