Abstract: An emitter arrangement includes a UV irradiation source, a cladding tube surrounding the UV irradiation source, and a UV-C sensor. The cladding tube has an end face on an open end. The UV-C sensor has a sensitive area, wherein the UV-C sensor is in optical connection with the end face of the cladding tube, so that the sensitive area of the UV-C sensor can detect the UV irradiation emerging from the end face of the cladding tube during the operation of the UV irradiation source.
