A novel method for the thermal characterization of thin films is presented. Free-standing films are illuminated and the resulting temperature distribution of the films is captured in steady state or dynamically via IR microscopy. Analytical and numerical models are used to obtain parameters such as the thermal conductivity, the heat capacity, and the effective emissivity from the micrographs. The method is validated for a wide selection of materials demonstrating excellent agreement with literature.
