Abstract
An endoscopic instrument (48) includes a tubular shaft (63) with an objective lens (1, 45), arranged at a distal tip (49), with an arrangement (3) of connected lens elements (5, 7, 9, 11, 13) having optical properties and following each other along an optical axis (15). The arrangement has a polygonal and at least hexagonal cross-section that is perpendicular to the optical axis. The lens is inserted interlocking, friction-locking and/or bonded in an imaging channel (51) of the distal tip. The imaging channel includes a first distal imaging channel section (51a) into which the objective lens is inserted, and a second imaging channel section (51b), with a greater inner diameter, arranged proximally of the first imaging channel section. An image sensor unit (17) bond connected to the objective is arranged in the second imaging channel section. The image sensor unit has greater lateral dimensions than the objective lens.
