Optical observation device with at least one visual observation beam path

Optical observation device with at least one visual observation beam path, which has at least

• an objective lens, that is to be turned in an operating position to a target object to be observed and images the target object,
• an eyepiece to be turned to an eye of an observer,
• an Abbe König prism system, Porro prism system or Schmidt Pechan prism system, arranged in the at least one visual observation beam path between the objective lens and the eyepiece, for image inversion of the at least one visual observation beam path,
• a display device for displaying an additional image in the visual observation beam path to the observer, and
• a device for image superposition, which has a holographic optical element, and which uses the holographic optical element to superpose onto the image of the display device the image of the target object to be observed in an intermediate image plane of the visual observation beam path, wherein the Abbe König prism system, the Porro prism system or the Schmidt Pechan prism system is provided with the at least one holographic optical element of the at least one device for image superposition.
