A videoendoscopic system () including an endoscope optical system () and a camera portion (), the endoscope optical system () having an elongated shaft () through which an optical image guide () and a fiber light guide () pass, and an end housing (), which is proximally connected to the shaft () and has an image exit window () and a light entry window () with radiation directions that are parallel to one another and to the axis of the shaft (). The camera portion () includes a camera housing (), from which an image signal cable () and a light guide cable () pass out, and an image entry window () and a light exit window (), which are arranged with parallel radiation directions at a distance from the windows () in the end housing () and the end housing (). The camera housing () is constructed with a rotationally fixedly lockable coupling device () for coupling the windows () to one another in a centering manner. The the coupling device has a cylinder () on one of the housings and a matching bore () on the other housing (). The windows () are arranged in the end wall () of the cylinder () and the base wall () of the bore ().

Videoendoscopic system

An endoscope having a tubular stem that, at its distal end, houses a camera and a distally pointing illumination device. The tubular stem defines an empty space extending from the camera in the proximal direction. The empty space receives a camera cable and is used to house implements useful during operation of the endoscope in a surgical procedure.

Endoscope

A medical endoscope with a video camera, a substantially tubular outer housing, which surrounds a substantially tubular inner metallic housing, and a light guiding fiber bundle. The inner housing surrounding a rod lens image guide disposed distally of the camera in a vapor-tight manner. The camera is disposed within the inner housing.

Medical endoscope with a video camera

An endoscopic optical system includes an elongate metal housing with a circular opening in its end in which a transparent window is received. The window has a cylindrical outer edge surface which is metallized over at least part of its area and is opposed to the cylindrical internal surface of the opening. An annular solder joint is provided in the gap between the opposed cylindrical surfaces. The solder joint has a thickness in the direction perpendicular to the window which is only a proportion of the thickness of the window.
