Abstract

A manipulator is provided for a surgical microscope in order to deflect a laser beam on the viewed operating area, the movement of a handle being transmitted via a lever mechanism to the movement of a mirror which reflects the laser beam to a point and via a path within the viewed operating area. The sensitivity of transmitted motion can be adapted to the selected magnification of the surgical microscope by changing the length of a transmission lever in order to change its point of motion pick-off from the handle.
