NUCLEAR-ABSORPTION SPECTROMETER, BASED ON ZEEMAN EFFECT Russian patent published in 2013 - IPC G01N21/31 G01J3/42 

FIELD: instrument making.

SUBSTANCE: spectrometer comprises optically coupled source of radiation with a wave length corresponding to resonant absorption of a determined element, a polariser, an optic modulator, a phase plate and an atomiser, arranged in the permanent magnetic field, optically coupled monochromator and receiver of radiation, a system of signal registration and processing, electrically connected with the receiver of radiation and synchronised with the optic modulator, and also a device of conversion of radiation optically coupled with the atomiser and the monochromator, made in the form of the optically coupled second polariser and a bundle of light guides with alternating profile, besides, the input end of the bundle of light guides has the shape matching with the profile of the cross section of the bundle of radiation, and the output end has the extended shape, and it is matched with the input slot of the monochromator.

EFFECT: increased illumination of a spectrometer and reduced time of analysis.
