Thermal radiation source and method for measuring the exact temperature and/or radiated radiant flux of the thermal radiation source

Abstract

The invention relates to a thermal radiation source which comprises a housing, an electrically operated radiation element arranged in the housing and an exit window through which radiation emitted by the radiation element is emitted from the housing, and to two methods for measuring the temperature of an exit window of the thermal radiation source and/or the radiant flux through an exit window of radiation emitted by the thermal radiation source. The problem of developing a possibility of being able to measure the radiant flux emitted by a thermal radiation source and/or the surface temperature of the exit window is solved by virtue of the exit window having a pass region, a contacting region and a measurement region, the measurement region and the pass region being formed separately from one another and/or with a partial overlap, with a temperature and/or radiation sensor being arranged within the measurement region of the exit window, the temperature and/or radiation sensor being electrically contacted via the contacting region.
