SPECTROMETER Russian patent published in 2009 - IPC G01N23/223 G01J3/28 

FIELD: physics; measuring.

SUBSTANCE: used for qualitative and quantitative determination of a chemical compound of substances. The spectrometer is included consistently located by the lighter with a radiant single-curved and continuous radiation, the compartment for samples in which one of interchangeable meshes can be erected for the sample-atomisator, the basin, the holder of firm samples, a dispersive unit and the positionally-sensitive photodetector, capable to change the orientation concerning a direction of a variance of a dispersive unit, so maintenance of excitation of spectrums of fluorescence with monochromatic radiation with smoothly changeable wave length in a compartment for samples is located a mesh containing a rotary diffraction grating with the reading mechanism, an exit slit with adjustable breadth, to a ditch with explored substance and the objective, thus radiation of a radiant with a continuous spectrum by means of an objective of the lighting plan is projected on a rotary diffraction grating with the reading mechanism developing the given diffraction grating, diffracted monochromatic radiation is oozed with an exit slit and gets to a basin, raising fluorescence of explored substance, radiation of fluorescence of explored substance by an objective of a mesh and an objective of lighting system is transferred on an input crack of a dispersive knot regulated on breadth.

EFFECT: expansion of functionality of a spectrometer in a mode of the fluorescent analyser without changes in the optical plan of the lighter of a spectrometer, increase of accuracy and correctness of the fluorescent analysis.
