APPARATUS AND METHOD OF MEASURING LIGHT ABSORPTION ON A TEST SAMPLE AND MEASURING TO ESTABLISH CONFORMITY ON A REFERENCE SAMPLE Russian patent published in 2020 - IPC G01N21/31 

FIELD: measurement technology.

SUBSTANCE: disclosed are devices and methods for measuring light absorption on a test sample and measurement to establish conformity on a reference sample. Method includes a step of moving a receiver carrier of a control sample of a device for arranging a first receiver of a control sample, received in carrier in second position on light path, stage of direction of light from lighting system to detection system along light path to perform light absorption measurement on first reference sample, in second position, carrier movement stage for first receiver location outside of light path, stage of placement of a test specimen receiver in a holder of a test specimen of a test sample of said device on a light path in a first position different from a second position, and a step of directing light along the light path to perform light absorption measurement on the test sample contained in the sample holder in the first position.

EFFECT: disclosed are devices and a method of measuring light absorption on a test sample and measuring to establish conformity on a reference sample.
