Patent ID: 7569013

Claim:
An endoscope optics ( 1 ) comprising: a fiber tube ( 3 ) and an outer tube ( 2 ) receiving a fiber tube ( 3 ) the fiber tube ( 3 ) receiving an image guide and separating it from optic fibers ( 11 ) arranged between the tubes ( 2 , 3 ) the image guide comprising a distal objective lens being configured to look downward with its line of sight at an oblique angle relative to an axis of the outer tube ( 2 ), the distal end face ( 5 ) of the endoscope optics ( 1 ) being configured perpendicularly to the line of sight, the optic fibers ( 11 ) comprising a lateral bundle portion ( 12 ) terminating in the end face ( 5 ) on a side of the fiber tube ( 3 ), the distal end portion of the fibers of the lateral bundle portion ( 12 ) being bonded and being aligned substantially parallel to the line of sight, wherein the bundle portion ( 12 ) is enclosed at its distal end portion by a guide duct ( 9 ) which is bounded at its inside by the outside of the fiber tube ( 3 ), at its outside by the inside of the outer tube ( 2 ), at its bottom by a first chamfer ( 15 ) running parallel to the line of sight and being part of a lower external protrusion ( 14 ) of the fiber tube ( 3 ), said external protrusion ( 14 ) touching the outer tube ( 2 ), and at its top by a second chamfer ( 16 ) running parallel to the line of sight and being part of an internal protrusion ( 7 ) of the outer tube ( 2 ), said internal protrusion ( 7 ) touching the fiber tube ( 3 ).
