1. A control device for a microscope, the control device comprising:
an operating device configured to be operated by a user to vary focusing and/or positioning of an optical imaging system of the microscope relative to a sample;
an actuator configured to adjust an aperture of a detection pinhole which is included in the microscope so as to eliminate out-of-focus light from detection light which is directed by the optical imaging system onto a detector of the microscope; and
a processor configured to detect a predetermined operating condition in response to a user operation of the operating device and to control the actuator to vary the aperture of the detection pinhole upon detection of the predetermined operating condition,
wherein the processor is configured to evaluate image data output from the detector, and
wherein the processor is configured to control the actuator based on the evaluation of the image data to adjust the aperture of the detection pinhole.
