The ultrasonic field of the ultrasonic cleaning is emitted by a protection device (60) into the air to provide a protection zone (50) around the optical surface (30) of the sensor (20) such that a contact of the optical surface (30) with the environmental pollutants (40) is avoided, wherein the environmental pollutants (40) are moved and/or destroyed in the air away from the sensor (20) if they enter the protection zone (50), and wherein the protection zone (50) provides a contactless cleaning of the sensor (20)",
