Abstract
A method and device are provided for cleaning of an optical position measurement system in a coating installation. The optical position measurement system includes a cantilever, and a sensor head having a radiation inlet and/or outlet for the reception and/or emission of an optical signal, at a free end of the cantilever. For tempering of the sensor head, a local thermoregulation is applied using a heater and/or cooling device for heating and/or cooling of the sensor head depending on thermal conductivity of material of at least the sensor head and depending on secondary heat in the coating installation.
