    Abstract: A fluorescence image analyzer, analyzing method, and pretreatment evaluation method capable of determining with high accuracy whether a sample is positive or negative are provided. A pretreatment part performs pretreatment including a step of labeling a target site with a fluorescent dye to prepare a sample. A fluorescence image analyzer measures and analyzes the sample. The fluorescent image analyzer includes light sources to irradiate light on the sample, imaging part to capture the fluorescent light given off from the sample irradiated by light, and processing part for processing the fluorescence image captured by the imaging part. The processing part extracts the bright spot of fluorescence generated from the fluorescent dye that labels the target site from the fluorescence image for each of a plurality of cells included in the sample, and generates information used for determining whether the sample is positive or negative based on the bright spots extracted for each of the plurality of cells.

    Abstract: A flow cytometer, in which detection of light generated from a particle is less likely to be affected by change in a flow velocity of a liquid flowing in a flow cell, is provided. The flow cytometer includes: a flow cell (10) in which a liquid flows; a liquid sending unit (40) configured to send the liquid into the flow cell (10); a controller (300) configured to obtain information related to a flow velocity of the liquid flowing in the flow cell (10); a light source (121) configured to irradiate the liquid flowing in the flow cell (10) with light; and a detector (162) configured to detect light generated from a particle in the liquid irradiated with light. The controller (300) changes a liquid sending condition for the liquid sending unit (40), based on the obtained information related to the flow velocity.

    Abstract: Disclosed is an optical system including: a light source configured to emit light; an irradiation optical system including a diffractive optical element on which the light is incident, the irradiation optical system being configured to apply illumination light in which a plurality of diffracted lights generated by the diffractive optical element are distributed; a flow cell in which a sample containing cells is caused to flow to a position at which the illumination light is applied by the irradiation optical system; and a light receiver configured to receive light generated from each cell flowing in the flow cell, upon application of the illumination light by the irradiation optical system. The illumination light includes zero-order diffracted light whose relative intensity relative to another diffracted light is not greater than 10 times. The irradiation optical system applies the illumination light to a position through which the cell in the flow cell passes.
