A probe system includes a scanning head and a transceiver element. By touching a stylus, a sensor element is able to generate a sensor signal. The scanning head and the transceiver element are configured such that a wireless information transmission is able to be established between them. The probe contact information is able to be transmitted from the scanning head to the transceiver element by a first signal whose carrier wave is an optical wave, and furthermore, additional information is able to be transmitted between the scanning head and the transceiver element by an additional signal whose carrier wave is a radio wave.
