'Apparatus for measuring the emittance of materials from far infrared to visible wavelengths in extreme conditions of temperature'
, Infrared Phys. Technol. 69 96-101 (2015) doi:

A computer controlled circular turntable equipped with a blackbody reference and an integrated axisymmetric heating system based on a CO2 laser is at the heart of the reported device. It allows performing emittance measurements in the spectral domain ranging from far infrared up to visible light and in a wide range of temperature. The apparatus includes two spectrometers and was built to achieve optimal experimental conditions of measurement, i.e. environmental stability and single optical path for the acquisition of the thermal fluxes. The specific design of the apparatus is firstly described; applied procedures for the characterization of the blackbody reference, laser heating and the retrieval of the emittance spectra are given after. Finally measurements obtained for ruby, NdGaO3 and platinum are presented to illustrate the capacities of the apparatus.
