Abstract: An endoscope has a shaft, a head disposed at a proximal end of said shaft and a light connection disposed at said head. Optical fibers extend from said proximal light connection to a distal end of said shaft. A sleeve in which a proximal end section of said light fibers is fixed is designed in such a way that it can be introduced in a linear movement without turning it into the light connection. Said sleeve is axially movable in said connecting piece.

Abstract: The invention relates to an eyepiece unit with an eyepiece mounted in an eyepiece frame and with a coupling element for inserting the eyepiece frame. According to a first embodiment, the eyepiece is mounted so that it can slide axially in the eyepiece frame and can be fixed so that it is individually adjustable in the eyepiece frame. To ensure an easy and rapid adjustment in an eyepiece unit, it is proposed with the invention that the eyepiece can be fixed in the eyepiece frame without screws. According to a second embodiment, the eyepiece frame is mounted in the coupling element so that it slides perpendicularly to the longitudinal axis for adjustment. It is fixed in this adjustment position, according to the invention, because the eyepiece frame can be fixed in the coupling element without screws.

Abstract: An endoscope, comprising an elongated rigid shaft and an optical imaging system arranged at a distal end of the shaft for receiving light from an observation area, wherein the optical imaging system is pivotable with respect to the shaft about a first pivot axis which runs about transversely to a longitudinal axis of the shaft. The optical imaging system is pivotable with respect to the shaft about at least a second pivot axis, which is spaced from the first pivot axis and runs about transversely to the longitudinal axis of the shaft, and an overall pivot range of the optical imaging system about the first and at least second pivot axis is at least 150° from the longitudinal axis of the shaft.

Abstract: A device for positioning at least one optical component inside an endoscopic system has a housing through which an optical axis of the endoscopic system extends and in which the at least one optical component is arranged. The at least one optical component can be pivoted into the beam path and back out of the beam path about a pivot axis extending substantially parallel to a longitudinal axis of the housing, the at least one optical component being arranged on a support which is pivotable about the pivot axis. A smallest distance of an inside wall of the housing from the pivot axis is smaller than a greatest distance of the pivot axis to an outer edge of the at least one optical component.

Abstract: An endoscope has an outer tube that is joined to an optical head having an observation element at its end, which elements are sealingly fitted forming a first module element. An inner tube sealingly fitted together with a housing containing optical elements form a second module element having the optical components hermetically closed. The second module element is disposed in the first module element having its distal ends rigidly and sealingly fitted together. The housing of the second module elements extends into said optical head of that first module element and is supported therein allowing relative movement between housing and optical head when thermally stressed.
