SPECTRAL-SELECTIVE PORTABLE RAMAN-LUMINESCENT ANALYSER

摘要

FIELD: physics, optics.SUBSTANCE: invention relates to optical analysis of the composition of a substance based on Raman and luminescence spectra and a spectral-selective portable Raman-luminescent analyser. The spectral-selective portable Raman-luminescent analyser further includes a microscope lens or a microscope and a one- or two-dimensional sample translator connected to a computer. The analyser is adapted to control a sample movement device and synchronise step-by-step sample scanning and identification of a substance at each step while focusing a laser beam by the microscope lens into a spot of micrometre or submicrometer dimensions.EFFECT: high sensitivity and resolution and avoiding the need to decode complex spectra multi-component mixtures.1 dwg
