Abstract: A rigid endoscope optics including an outer tube (1) of which the distal aperture is closed by a window (2) affixed to the outer tube in a sealed manner. The outer tube encloses an image transmitter (4, 5) running through it and a light guide (6) running parallel to the transmitter, the transmitter and pipe being configured by their distal ends (5, 7) looking and radiating, respectively, through the window. The light guide is cross-sectionally separated from the image transmitter's cross-section at least in the region of defined between their distal ends and the window by an optically opaque partition (3). The partition rests by its distal edge against the window, wherein an elastic and opague insert is disposed between the distal end of the partition (3) against the window (2).
