ABSTRACT:
In an endoscope optical system comprising an inner tube accommodating the optical components of the system and an outer tube enclosing the inner tube, optical fibers are disposed in the chamber defined between the two tubes, for transmitting light to a site to be inspected by means of the endoscope. For uniform illumination of the site to provide images to satisfactory quality, coaxial or paraxial arrangement of the inner tube within the outer tube is achieved by bridging the chamber by means of webs extending longitudinally of the tubes, the optical fibers being accommodated in sub-chambers defined between the webs.
