DEVICE TO MEASURE INDEX OF REFRACTION Russian patent published in 2014 - IPC G01N21/41 

FIELD: measurement equipment.

SUBSTANCE: invention relates to optical electronic instrument making, namely, to refractometric facilities of measurement of a refraction index in liquid and paste-like substances, powders and similar substances. The device to measure a refraction index comprises at least one feeler probe connected with a recording module by means of a light guide, at the same time the feeler probe may be made for instance using a ceramic ferrule, acting the role of the light guide rim and a planoconvex lens, or by other methods.

EFFECT: invention makes it possible to create a simple-to-manufacture device to implement multi-point continuous measurement of a refraction index.
