Patent ID: 7034270

Claim:
A scanning laser microscope comprising: a laser beam source which outputs laser beam; a dispersive element which disperses light emitted from a sample when irradiating the sample with the laser beam and makes spectrum; an image formation element which forms an image of the spectrum made by the dispersive element; a wavelength band extraction portion which is arranged in the vicinity of the image position of the spectrum formed by the image formation element and extract light in at least one wavelength band from the spectrum; at least one photodetector which detects the light in the wavelength band extracted by the wavelength band extraction portion; at least one optical element which is selectively arranged between the sample and the dispersive element; and a correction portion which corrects a positional relationship between the wavelength band extraction portion and a position of the spectrum image which is displaced in the dispersion direction due to a change in an angle of the light entering the dispersive element caused by switching the optical element.
