1. A disk scanning apparatus used in combination with an imaging optical system that collects fluorescence emitted from a sample and forms an optical image of the sample and with an imaging apparatus that captures an image of the sample, comprising:
a rotating disk including a shielding part that blocks off light and a transmitting part that transmits light on a disk surface, with the disk surface placed so as to be positioned on a focal plane of the imaging optical system in which the optical image of the sample is formed, and configured to rotate on an axis orthogonal to the disk surface; a relay optical system configured to perform relaying of the optical image of the sample formed on the disk surface to the imaging apparatus combined with the disk scanning apparatus, including a front group having a positive power and a rear group having a positive power, in this order from the rotating disk side, and configured so that a luminous flux between the front group and the rear group becomes an afocal luminous flux; and a structure configured to make a distance between the front group and the rear group variable. |
