Abstract
A light scanning type confocal microscope includes a light source unit that projects an excitation light beam, a scanning optical system that scans the excitation light beam, an objective lens that applies the excitation light beam to a sample, a separation optical element that separates the excitation light and detection light generated by the sample, a confocal detection unit that obtains a confocal effect, and a spectral detection device that spectrally detects the detection light. The spectral detection device has a spectroscopic element that spectrally separates the detection light, a light extracting unit that extracts light in a wavelength band from the light spectrally separated by the spectroscopic element, a detector that detects the light extracted by the light extracting unit, and a wavelength band shifting unit that shifts a wavelength band of light to be extracted by the light extracting unit.
