EMITTER OF ABSOLUTELY BLACK BODY TYPE

摘要

The invention relates to an optical thermometry and can be used in optical pyrometry for measuring high temperatures, as well as infrared radiation standards. Proposed emitter blackbody type comprising a set of tightly coupled elements, the radiating surface of each of which is formed in the cross section in the form of a wedge with a sharp edge facing the radiation. In this case the radiating surfaces of adjacent elements are not in contact with each other, and on the emitting surface of the black coating is applied. A distinctive feature of the claimed utility model is that the elements are designed as identical flat plates, and the coating is glossy with emissivity in the infrared range of not less than 0.95. The technical result consists in simplifying the radiator manufacturing technology and improving the degree of blackness. 3 ZP f-ly 1 Fig.
