Abstract
A method of adjusting an optical apparatus that acquires an image of a sample includes the steps of moving a focusing section included in the optical apparatus in a direction in which a contrast of a first image of the sample increases, and adjusting an aberration amount occurring in the optical apparatus in a direction in which a contrast of a second image of the sample increases.
Claims11
A method of adjusting an optical apparatus that acquires an image of a sample, the adjustment method comprising the steps of:
- moving a focusing section included in the optical apparatus in a direction in which a contrast of a first image of the sample increases;
- and
- adjusting an aberration amount occurring in the optical apparatus in a direction in which a contrast of a second image of the sample increases,
- wherein an average value of frequency components of the second image is higher than an average value of frequency components of the first image.

An optical system comprising:
- an optical apparatus that acquires an image of a sample, the optical apparatus including an objective lens, a focusing section that changes a distance between the objective lens and the sample, and a correction device that corrects an aberration;
- and
- a control device that controls the optical apparatus, wherein
- the control device
- causes the focusing section to move in a direction in which a contrast of a first image of the sample increases, and
- changes setting of the correction device to adjust an aberration amount occurring in the optical apparatus in a direction in which a contrast of a second image of the sample increases, and
- an average value of frequency components of the second image is higher than an average value of frequency components of the first image.
