Abstract: Provided is a spectral data acquisition method which can perform laser irradiation more uniformly while further reducing cell damage. The spectral data acquisition method involves receiving, by means of a spectroscope, Raman scattered light output from a cell by spirally irradiating an area in which the cell is present with laser light from the laser light source, and detecting a Raman spectrum in response to the received Raman scattered light by means of a charge-coupled device (CCD) detector.
