Abstract
Provided is a photoacoustic microscope, including: an objective lens configured to collect excitation light into a specimen, the excitation light in a wavelength range that is absorbed by an object to be observed; a detection light optical system configured to (i) form an image of a point light source of detection light in a middle portion of a pupil of the objective lens, the detection light having a wavelength that is different from the wavelength range of the excitation light, and (ii) emit the detection light onto the specimen by means of the objective lens; an optical scanning unit configured to deflect the excitation light and the detection light that enter the objective lens, for scanning the specimen; and a light detection unit configured to detect reflected light of the detection light that is reflected by the specimen.
