Abstract
A device by which the magnification stages of a magnification selector based on Galilean telescope systems can be adjusted by a motor. The magnification selector has a sensor that transmits the currently magnification stage to a control unit; in the control unit, an assignment of the magnification stages present on the magnification selector to a sequence of the magnification stages, organized based on size, is stored. For the user, there are operating elements connected to the control unit for selecting a magnification stage. In order to set the magnification stage selected by the user via the operating elements, the magnification selector has an actuator, which is connected to the control unit to receive appropriate control signals. Although provided in particular for slit lamps and surgical microscopes having eyepieces, the solution can also be applied in other ophthalmological devices or devices from other technical fields.
