Title:
OPTICAL DEVICE AND PHOTOACOUSTIC MICROSCOPE
Document Type and Number:
WIPO Patent Application WO/2019/216364
Kind Code:
A1
Abstract:
An optical device (100) is provided with: a first axicon lens (120) on which collimated light is incident, the first axicon lens (120) forming divergent ring-shaped light; a lens (130) on which the ring-shaped light formed by the first axicon lens is incident, the lens (130) forming ring-shaped collimated light; and a condensing mirror (140) for condensing the ring-shaped collimated light formed by the lens. A photoacoustic microscope (10) is provided with the abovementioned optical device and a detector (160) for detecting an acoustic wave generated by the light condensed by the condensing mirror.
