A tilting system for an observation device, in particular for a microscope, with at least one objective device and at least one optical device for passing at least one beam path from an entrance region to an exit region of the tilting system is described, wherein the optical device has at least one optical element in the form of a prism for tilting and for image reversion of the beam path as well as for guiding it further into at least one ocular device. According to the invention, a particularly cost-favorable and structurally simple configuration of the tilting system with a mechanical structural length that is simultaneously as small as possible is provided by configuring the optical elements for tilting the beam path as well as at least one prism for image reversion in a special way and by arranging them in a specific manner relative to one another in the beam path. In addition, an observation device with a corresponding tilting system is described.
A tilting system for an observation device with at least one objective device and at least one optical device for passing at least one beam path from an entrance region to an exit region of the tilting system, wherein the optical device has at least one optical element in the form of a prism for tilting and for image reversion of the beam path as well as for guiding it further, wherein an optical element in the form of a 180° prism is provided for image reversion in the beam path and that the 180° prism is arranged crosswise to the tilting system extending from the entrance region to the exit region, wherein at least one deviating prism is provided in at least one beam path, upstream and downstream of the 180° prism, as viewed from the entrance region of the tilting system, wherein two axes of rotation are provided running perpendicular to the direction of the beam entering into the tilting system in its entrance region, around which the 180° prism and the at least one deviating prism are moved relative to one another, wherein the system is formed for the passage of two beam paths, whereby in each of the two beam paths at least one objective device and at least one optical device are provided and whereby a device for adjusting the distance between the two beam paths is provided in the exit region of the tilting system, wherein the device for adjusting the distance is formed as a lens system and that a lens system is provided in each of the two beam paths, and wherein the lens system is provided in at least one axis or rotation which the 180° prism and the at least one deviating prism are moved relative to one another.
