Patent ID: 7980758

Claim:
Apparatus for non-contact measurement of the temperature of a plurality material samples arranged in a vacuum chamber, wherein each material sample is arranged on a support inside of said vacuum chamber and in thermal contact with the support, comprising: a radiating energy source external to said chamber for illuminating said each sample with radiation, through a window on a wall of said vacuum chamber, said window being made of a material that is transparent for said radiation, such that said each sample is subjected to a predetermined thermal cycle; and a plurality of thermo-optical temperature measurement components for measuring temperature of said each sample using an infrared radiation emitted by said each sample and crossing the wall of said vacuum chamber through a window made of a material that is transparent for said infrared radiation; and wherein each thermo-optical temperature measurement component is associated with a beam scanning module comprising a mobile mirror arranged on an optical path of said infrared radiation and two motor-powered components for rotationally moving said mobile mirror along two orthogonal axes, such that said infrared radiation is deviated and a two-dimensional scanning is obtained for said each sample by measuring spot focused on surface of said each sample; and wherein said each sample is made of a thin film arranged on said support wherein the surface of said support in thermal contact with said each sample is convexly curved to provide a convex surface, and wherein said support comprises attachment parts in upper and lower zones of said each sample for pressing firmly against said convex surface.
