1. 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).
