Abstract:
1. A laser scanning microscope comprising: a laser light source which emits a laser light having a changeable wavelength; a correction amount determination unit that determines a correction amount for correcting an optical axis shift of the laser light due to a change in the wavelength of the laser light emitted from the laser light source; an optical axis adjusting unit that adjusts an optical axis of the laser light emitted from the laser light source; a scanning unit that performs two-dimensional scanning with the laser light emitted from the laser light source; an objective lens that focuses the laser light from the scanning unit to a specimen and collects fluorescence emitted from the specimen; a light detector that detects the fluorescence collected by the objective lens; and a control unit that changes the wavelength of the laser light from the laser light source synchronously with the scanning of the laser light performed by the scanning unit while controlling the optical axis adjusting unit based on the correction amount determined by the correction amount determination unit.
