ABSTRACT:
A periscope-like sighting device is proposed which comprises an optical system comprising a plurality of elements arranged within a housing for localizing and tracking a target. In order to obtain as great as possible a field of observation, the optical system comprising a first deflection prism, an objective lens or lens system, a first beam splitter, a second beam splitter and a second deflection prism is arranged in the housing sloping backward in the direction of incident radiation and in relation to a vertical rear housing wall. A main mirror is associated with the first beam splitter and is journaled in a mirror head arranged sloping backward in the housing to be pivotable about a first axis and rotatable about a second axis. In order to achieve a range-finding of the target, a laser range finder can be arranged on the housing of the sighting device and is preferably subdivided into a laser transmitter portion and a laser receiver portion and the principal components of the laser receiver portion are arranged within the housing.
