Abstract

The panoramic periscope has a panoramic head and a tube. In the panoramic head is mounted a viewing mirror movable in elevation and azimuth, upstream of which is arranged an at least bispectral front window. Various measuring or observation devices, for example a daylight and night vision device and a laser range-finder, are provided in the tube. Panoramic head and tube are connected to one another by an optically transmitting component such as a transparent cylinder or by webs. As a result, the visual beam path can be reflected out laterally by means of a spectrum divider, so that the latter can be arranged in the observation beam path immediately downstream of the viewing mirror in the upper tube portion. In addition to a compact design, this also makes possible a separate, better optimization of the optical systems for the daylight and night vision range.
