Description

technical field [0001] The invention relates to a microsphere spectrum analysis instrument, in particular to a microsphere spectrum automatic analyzer and a spectrum automatic analysis method. Background technique [0002] According to the working principle of modern spectrometers, spectrometers can be divided into two categories: classic spectrometers and new spectrometers. Classical spectroscopic instruments are based on the principle of spatial dispersion; new spectroscopic instruments are based on the principle of modulation. Classical spectroscopic instruments are all slit spectroscopic instruments. The modulation spectrometer is non-spatial spectrometer, which uses a circular hole to enter light. According to the spectroscopic principle of the dispersion component, the spectrometer can be divided into: prism spectrometer, diffraction grating spectrometer and interference spectrometer. [0003] Whether it is a classic spectrometer or a new spectrometer, it requires pr...
