Abstract:
An endoscope optics (1) fitted with lens elements (4, 85,86) and with a securing device (6, 26, 30, 40, 50, 60, 80) to secure the lens elements (4, 85, 86) against shifting on account of impacts, wherein the securing device is a circumferentially expansible tube (6, 26, 30, 40, 50, 60, 80) which jointly encloses in an elastically stressed manner, at at least one abutment surface, mutually adjoining ends of two lens elements (4, 85, 86), said circumferentially expansible tube having an inside diameter that is less than an outside diameter of the lens elements so as to engage and hold said lens elements against movement in more than one direction and thereby insure axial alignment of said lens elements.
