Abstract

A method and apparatus for actuating an acousto-optical component for manipulating light passing therethrough, in particular for manipulating the illumination and/or detection light in the beam path of a microscope, preferably a laser scanning microscope, where the illumination and/or detection wavelength is adjusted by means of at least one frequency generator connected to the acousto-optical component and controlling the manipulation, the frequency generator generates a signal which generates a spectral spread for the intensity distribution of the wavelength of the illumination and/or detection light for ensuring a temperature-independent manipulation. Actuation is effected by two or more actuation signals in such a way that two or more overlapping and/or superposing main lobes of the transfer function of the acousto-optical component or main maxima are generated.
