A microscope system includes: a microscope optical system including an ocular lens, the microscope optical system being configured to form an optical image of a sample on an object side of the ocular lens; a processor configured to generate, based on examination information regarding examination to the sample and magnification information regarding a magnification of the microscope optical system, image data of a comparative image for comparison with the optical image; and a superimposition device configured to superimpose, based on the image data generated by the processor, the comparative image onto an image plane on which the optical image is formed.
A microscope system comprises: a light source; an objective lens; a stage; a two-dimensional image sensor that captures an image of a specimen placed on the stage; a focusing device that changes distance between the objective lens and the stage; and a control circuit, wherein the control circuit executes, during a movement period in which the stage moves in a direction orthogonal to an optical axis of the objective lens, focus control for controlling the focusing device based on focus evaluation information detected during the movement period, and exposure control for controlling an exposure period of the two-dimensional image sensor, and executes light emission control that causes the light source to emit light with different light emission intensities during the exposure period and during a focus evaluation period in which the focus evaluation information is detected.
A system for evaluating stem cell differentiation includes a storage configured to store a machine learned model that has learned success or failure of cell differentiation for a combination of a stem cell and a differentiation induction method, an acquisition unit configured to acquire a target cell image that is an image of a target cell that is a stem cell to be induced to differentiate and differentiation induction information that is information related to a differentiation induction method applied to the target cell, and a processor configured to output differentiation success or failure information indicating an inference result related to success or failure of differentiation of the target cell into a desired cell type on the basis of the target cell image, the differentiation induction information, and the machine learned model. The differentiation induction information includes information indicating the type of a stimulus given to the target cell.
A control method for displaying inspection images causes a processor to display an image of a model of an inspection object including a plurality of inspection sites, in a first display region and display first inspection information relevant to at least one inspection site, in a second display region, where the at least one inspection site is selected from the plurality of inspection sites in the image of the model displayed in the first display region. The control method further causes the processor to display inspection information prior to the first inspection information, as second inspection information relevant to the model, in a third display region, concurrently with one or more of the first display region and the second display region.
In an inspection assistance method, a processor accepts inspection portion information related to an inspection portion. In the inspection assistance method, the processor acquires a result of an inspection of the inspection portion corresponding to the inspection portion information from a storage media: In the inspection assistance method, the processor displays inspection assistance information on a display. The inspection assistance information notifies a user of information related to an abnormality of the inspection portion detected in a previous inspection. In the inspection assistance method, the processor displays an image of the inspection portion on the display.

An immersion objective includes a first lens group including a meniscus lens, a second lens group including a cemented lens and having a positive power, and a third lens group having a negative power. The third lens group is formed of a front group having a concave surface on a most image side and a back group having a concave surface on the most object side. Even when any of a plurality of immersion liquids used together with the immersion microscope objective is used, an amount of chromatic aberration at each of wavelengths in a range from 435.18 nm to 656.13 nm, which has an e-line as a reference, is smaller than a magnitude of depth of focus of the immersion microscope objective at the wavelength. The immersion microscope objective satisfies a following conditional expression.
