Claim Text:
1. A photoacoustic microscope, comprising: an excitation light source configured to emit excitation light, wherein the excitation light is in a wavelength range that is absorbed by an object to be observed; a detection light source configured to emit detection light, wherein the detection light has a wavelength that is different from the wavelength range of the excitation light; an objective lens configured to collect the excitation light into a specimen; a beam combiner configured to synthesize the detection light coaxially with the excitation light; a condenser lens arranged between the detection light source and the beam combiner, wherein the condenser lens is arranged at a position that forms a point image of the detection light source in a middle portion of a pupil of the objective lens, so that the detection light is emitted onto the specimen by means of the objective lens; an optical scanning unit arranged between the beam combiner and the objective lens, wherein the optical scanning unit is 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.
