Patent ID: 7158293

Claim:
A tube for a microscope, comprising: a tube housing; an adaptation interface; a beam guidance device; an operator interface; and a beam deflecting device configured to deflect a light beam coming from the adaptation interface to a first optical axis, the first optical axis at least locally extending substantially in a predefined plane so as to be guidable by the beam guidance device to the operator interface; wherein the beam guidance device includes a beam deflection unit, the beam deflection unit being configured to receive the light beam along a second optical axis and deflect the light beam to the operator interface along a third optical axis, the beam deflection unit being rotatable about an axis perpendicular to the second optical axis so as to vary a direction of the third optical axis; and wherein the tube housing, together with the beam guidance device and the operator interface, is movable relative to the microscope in a direction parallel to the first optical axis.
