DEVICE FOR MEASURING ENERGY PARAMETERS OF LIGHT RADIATION Russian patent published in 2021 - IPC G01J5/12 

FIELD: photometry.

SUBSTANCE: invention relates to the field of photometry and relates to a device for measuring the energy parameters of light radiation. The device contains a sealed case, temperature-sensitive elements, four identical quadrants, signal electrodes and a connector fixed on the back of the case. The sealed case is made in the form of a round cylinder. The temperature-sensitive elements are fixed on the front side of the case along the lines of its two mutually perpendicular diameters, and a hot junction of the measuring thermocouple is stamped into each temperature-sensitive element from the side of its lower base. Signal wires of all measuring thermocouples are electrically connected to the pins of the connector socket, which are allocated in a separate measuring group. Four identical quadrants are centering elements and a thermocouple hot junction is stamped into each of them. The signal wires of these thermocouples are electrically connected in opposite directions and are connected to the pins of the connector socket allocated to the setting group. A cold accumulator is installed on the rear side inside the case, which is pressed against the bundle of cold junctions of the measuring thermocouples.

EFFECT: invention improves accuracy of the obtained data on the distribution of energy density.
