Abstract: A videoendoscopic system (1) including an endoscope optical system (2) and a camera portion (3), the endoscope optical system (2) having an elongated shaft (4) through which an optical image guide (5) and a fiber light guide (6) pass, and an end housing (7), which is proximally connected to the shaft (4) and has an image exit window (10) and a light entry window (8) with radiation directions that are parallel to one another and to the axis of the shaft (4). The camera portion (3) includes a camera housing (15), from which an image signal cable (24) and a light guide cable (20) pass out, and an image entry window (18) and a light exit window (19), which are arranged with parallel radiation directions at a distance from the windows (8, 10) in the end housing (7) and the end housing (7). The camera housing (15) is constructed with a rotationally fixedly lockable coupling device (7, 16, 25, 26, 19) for coupling the windows (8, 19; 10, 18) to one another in a centering manner.

Abstract: A rigid endoscope optics (1) including a housing consisting of several housing parts (5, 8, 9, 6, 16) which hermetically encloses optic elements (3, 2, 4) and which is fitted with a hermetic connection (13, 14; 7, 15) between two housing parts (9,8; 9, 16) is characterized in that one (9) of the connected housing parts is made of PPS (polyphenylenesulfide) plastic or of PPSU (polyphenylsulfone) plastic, and the other (8, 16) connected housing part is made of PPS, PPSU or glass, the housing parts (8, 9, 16) being fitted with a metal coating (7, 13, 14, 15) at the connection site (13, 14; 7, 15) and are soldered to one another.

Abstract: A rigid endoscope optics (1) including a housing formed by several housing parts (5, 8, 9, 6, 16) that hermetically enclose optic elements (3, 2, 4) and are fitted with hermetic connections (7, 11, 13, 14, 15) between each other. At least one of the housing parts (8, 9) is made of plastic. At least at one of the connection sites of the plastic housing part (8, 9), the plastic has metal coating (11, 13, 14, 15) and the connection is a solder joint.
