FIELD: optics.
SUBSTANCE: invention relates to optical analysis methods. Method for laser scanning of liquids in hollow prisms includes formation of laser beams by means of separate laser modules with wavelengths of 405, 450, 488, 532, 589, 635 and 685 nm, which through the system of light filters are combined into one dense parallel beam, which, when passing through a hollow transparent prism filled with the analysed material, is refracted in accordance with the optical density of the material in the prism, wherein the nature of refraction of each of the laser beams passing through the prism with the analysed material is fixed on the screen and transmitted to the computer display, where it is compared with the nature of refraction of the same laser beams, which have passed and refracted through control materials, made from both solid transparent materials and liquids placed in a prism, with known chemical characteristics.
EFFECT: faster operation.
