ABSTRACT:
An endoscope optics receiving a fiber tube to separate optic fibers running between the tubes from an image guide fitted with a distal objective lens, the objective lens being configured to look downward at an oblique angle relative to the axis of the outer tube, the distal end face of the endoscope optics being configured perpendicularly to the line of sight, where a lateral bundle portion of the optic fibers, which is to the side of the fiber tube, terminates at distally bonded fibers substantially parallel to the line of sight, in the end face. The bundle portion is enclosed at its distal end zone by a guide duct. The guide duct is bounded inside by the outside of the fiber tube, outside by the inside of the outer tube, at the bottom by a first chamfer running parallel to the line of sight and being part of a lower external protrusion of the fiber tube touching the outer tube, and at the top by a second chamfer parallel to the line of sight of an internal protrusion of the outer tube touching the fiber tube.
