Zusammenfassung:	An apparatus for controlling an acousto-optical component influencing at least one of illumination light and detection light in a microscope is described. The apparatus comprises a radio-frequency generator for supplying the acousto-optical component with a radio frequency. The radio-frequency generator is configured to compensate deviations in the characteristics of the light due to temperature fluctuations in the acousto-optical component by adapting the radio frequency. The apparatus can be operated by generating a control signal for controlling the radio frequency of the radio-frequency generator; measuring the temperature of the acousto-optical component; adapting the control signal depending on the measured temperature; and sending the adapted control signal into the radio-frequency generator for compensating deviations in the characteristics of the light due to temperature fluctuations and can be used in optical coherence tomography, particularly white light interferometry, optical tweezers in lithography, and distance measurement.
