ABSTRACT:
An acousto-optical component is suggested, in particular for use in the beam path of an optical arrangement, preferably of a microscope, with a crystal for the passage of light. Sound waves are generated via an electrical transducer and passed through the crystal. The sound waves passing through the crystal affect the optical properties of the crystal and therefore the light passing through the crystal. For exerting a variable influence on the light passing through the crystal, the sound waves passing through the crystal, or the acoustic field in the crystal, are/is variable.
