FIELD: measuring equipment engineering.
SUBSTANCE: thermo-electric receiver contains receiving element, made of sapphire. Element is provided with additional absorbing layer on the side, opposite to radiation, in form of metallic film of alloy on basis of nickel. Absorbing layer is covered by anti-reflecting protective film cover, on which along periphery of receiving element, sections of thermal pair are positioned with even gaps between them. Cold soldered junctions of thermo-pairs are positioned in thermostat, all elements of receiver are positioned in thermo-stabilized body. Device is provided with substitution winding, mounted on periphery of receiving element on the side of radiation and made in form of connected groups of electrical heaters, positioned on receiving element in front of aforementioned gaps between sections of thermo-battery thermo-pairs.
EFFECT: increased precision of measurement.
