FIELD: registration of absorption spectra of small luminescent specimens.
SUBSTANCE: the absorption spectrum of small luminescent specimens is determined according to relation of intensities of light fluxes that have passed and not passed through the specimen, the luminescence of the standard specimen is used as the specimen through which the radiation flux has not passed, and the luminescence of the examined is used as the specimen through which the radiation flux has passed, and the absorption spectrum of the examined specimen is calculated according to the respective mathematical formula.
EFFECT: expanded functional potentialities due to the increase of the range of specimens suitable for measurements without special preparation of them.
