  • Patent number: 10288877
    Abstract: A microscopy system includes a microscope apparatus. The microscope apparatus has an objective and a correction device correcting for a spherical aberration, and obtains image data. The microscopy system further includes an estimator that estimates, on the basis of information on a medium placed between the objective and an observation target plane, an amount of spherical aberration that occurs in the microscope apparatus. The microscopy system determines, by use of a contrast value calculated from the image data obtained by the microscope apparatus and an amount of spherical aberration that is estimated by the estimator, a target set value that is a set value of the correction device, the set value corresponding to the amount of spherical aberration that occurs in the microscope apparatus.

  • Patent number: 10288861
    Abstract: A light sheet microscope includes an objective, an illumination optical system, a correction device, an image pickup device, a first adjustor, a second adjustor and a controller. The controller performs a first focus process and a spherical aberration correction process. The first focus process is a process in which the first adjustor is controlled on the basis of light that is from the light sheet plane and that is detected via the objective so that the light sheet plane and a focal plane become closer when a relative position between the light sheet plane and a sample has been changed. The spherical aberration correction process is a process in which the correction device is controlled so that an evaluation value of the image obtained by the image pickup device becomes greater when the first adjustor has changed the relative position between the light sheet plane and the objective.
