OPTICAL ANALYZER, OPTICAL ANALYZING METHOD AND SAMPLE PREPARATION DEVICE Russian patent published in 2018 - IPC G01N21/35 

FIELD: measuring equipment.

SUBSTANCE: invention relates to an optical analyzer. Optical analyzer comprises an optically integrating cavity, formed by at least one optical light diffusing wall and adapted to contain a sample of a solid agricultural product, the sample consisting of one or more elements, and a light source, emitting light into the optically integrating cavity. Whereas the at least one optical light diffusing wall is utilized to convert emitted light to diffused light, and the sample is able to convert the diffused light to spectrally filtered light, to spectrally filtered light. Moreover, the optical analyzer is made to provide a substantially uniform density of photons in the integrating cavity and with the possibility of uniform illumination of the sample substantially from all spatial directions. Analyzer also contains a spectral sensor. Sample is confined in the optically integrating cavity, and the spectral sensor being exposed, to the spectrally filtered light.

EFFECT: technical result is to increase the accuracy of measurements and reliability of the device.
