Abstract: The invention relates to a switchable infrared filter, consisting of a diamond carrier material (1), whereon a filter material (6), which is made of a thermochromic material, is disposed on one side and which can be connected to a heating device (2, 3).

Abstract: The invention concerns a diamond body designed to enable thermal contacting with at least one source of heat (30) and presenting at least one recess (13, 15) defining an angular position in relation to the mechanical tensions generated by said or any source of heat (30). Consequently, the mechanical tensions generated at various temperatures, either, for example, by various expansion coefficients of the diamond body (12) or by the source of the heat (30) featured by one semi-conductor component, are at least partly compensated, resulting in the possibility to take advantage of the exceptional thermoconductive capacity and insulating characteristics of the diamond, including diamond bodies (12) of a relatively big size.
