Abstrakt EN: The contribution introduces a new experimental set-up for the measurement of high-temperature spectral-distribution of emissivity of thick coatings. The method is based on a typical arrangement using FTIR spectrometer analyzing the radiation of the laboratory blackbody and sample surface. Rotating mirror in between the blackbody and sample is used to change the optical path into the spectrometer emission port. Surface temperature of the sample is measured by noncontact infrared camera system. Sample heating up to 1200°C is established by electrical resistance heating block or high power laser with a galvo scanning head. Details about the mentioned set-ups and results of their application for the emissivity measurements are going to be reported. Advantages and disadvantages are discussed.
