Abstract

The invention contemplates an operation microscope in which three-dimensional viewing adjustment is possible with respect to an object (8) to be observed, all without forcing the surgeon or any co-observing person or instrumentality to move. To this end, the exit pupils and thus all viewing windows are positionally invariant, i.e., they are stationary and therefore can be securely related to a microscope support (5). An objective housing (7) in front of the microscope housing (1) is associated with all viewing systems (2, 3, 4), and this objective housing contains an objective of variable back focus as well as optical components (11, 12) for selective deflection of the observation ray path in each of two polar-coordinate directions. In making any one or all of the three-dimensional viewing adjustments, only elements of relatively low mass within the objective housing (7) need be moved.
