Abstract
An optical device includes a first axicon lens to which collimated light is incident and which is configured to form diverging ring-shaped light; a lens to which the ring-shaped light formed by the first axicon lens is incident and which is configured to form ring-shaped collimated light; and a condensing mirror that is configured to condense the ring-shaped collimated light formed by the lens. A photoacoustic microscope includes the optical device described above and a detector that is configured to detect an acoustic wave caused by light condensed by the condensing mirror.
