Abstract
A centrifuge microscope includes a disk which is rotatable around a rotation axis and which is provided with a sample chamber for accommodating a sample. An observation optical system is provided which includes an objective lens which is positioned such that the sample chamber crosses an optical axis of the objective lens as the disk rotates. A pulsed laser source is provided for emitting a pulsed laser to the sample at a timing at which the sample chamber crosses the optical axis of the objective lens. And a delay time adjusting section is provided for adjusting a delay time of an emission timing of the pulsed laser in accordance with a rotational speed of the disk.
