Abstract
A cleaning device for cleaning a transparent element of an optical or optoelectronic device with a fluid cleaning agent, includes a housing in which the device is arranged. The housing is equipped with an annular channel which can be filled with the cleaning agent via a cleaning agent inlet and encloses at least some areas of the transparent element, and at least one nozzle which is designed to deflect the cleaning agent onto the transparent element and is supplied from the annular channel. The cleaning device allows an increase of uptime and ensured functionality of the optical or optoelectronic device in all weather conditions and operating conditions or to maintain a high degree of uptime and ensured functionality at all times. At least one electrically conductive heating element is provided for heating the annular channel and/or the area of housing directly adjoining the annular channel or the cleaning agent inlet.
