METHOD FOR CALIBRATION OF INTEGRATING CHAMBER Russian patent published in 2023 - IPC G01N21/27 G01J3/02 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the field of measuring equipment and concerns a method for calibrated measurement of a sample, using an integrating chamber. The method includes stages, at which spectral data of the sample is received by use of the integrating chamber with the sample placed inside the integrating chamber. In addition, the first spectral information is received, characterizing the chamber, formed by use of an integrating chamber with a reference object. The result of measurement is obtained based on spectral data of the sample by use of mathematical processing, in which spectral information characterizing the chamber is used as input information. In addition, after the stage of reception of the first spectral information, the second spectral information is received, characterizing the chamber, by use of the integrating chamber with the specified reference object or another reference object identical to the specified reference object, and it is compared with the first spectral information. If comparison indicates that the second spectral information differs from the first spectral information, then the second spectral information is used, when receiving the result of measurement.

EFFECT: increase in the accuracy of measurements.
