METHOD OF INTEGRAL RADIATING ABILITY MEASURING USING MICRO FURNACE (VERSIONS) Russian patent published in 2017 - IPC G01J5/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measuring equipment and can be used in materials transmitting properties analyzing. Method of integral emissivity measuring consist in solid body analyzed sample fixation in separate chamber, said sample heating to preset temperature T on its surface and recording by heat sensor of radiant energy emitted from analyzed sample surface. Prior to heating analyzed sample is placed into graphite block body, surrounded by heat insulation with ultra low heat conductivity, and performing graphite block heating by direct laser radiation supplying to graphite block local zone until this block heating to preset temperature T and simultaneous heating of analyzed sample arranged in this block body by heat transfer from graphite block to sample to condition of their heating temperatures equality. Then analyzed sample is removed from graphite block body and placed in full radiation pyrometer sight area acting as radiant energy receiver. Then performing sample natural cooling due to heat loss by radiation while simultaneously recording sample cooling down rate caused by total radiation losses from its full surface, for cooling down thermogram measurement and integral emissivity calculating.

EFFECT: increasing accuracy of obtained results.
