PROBLEM TO BE SOLVED: To provide a photoacoustic objective optical system capable of reducing generation of non-axisymmetric aberration.SOLUTION: A photoacoustic objective optical system comprises: a light converging part 10 for converging excitation light; an acoustic wave reflecting part 20 for transmitting the excitation light from the light converging part 10 and reflecting acoustic waves incident from a light emitting surface 22b of the excitation light; and an aberration correction part 30 having an optical surface for correcting non-axisymmetric aberration generated in the excitation light when the excitation light is transmitted through the acoustic wave reflecting part 20. |
