摘要： To provide a technology of optimizing a suction condition of a microparticle.
The present technology provides
an optimizing method of a suction condition of a microparticle including:
a particle number counting step of detecting a time point when a microparticle passes through a predetermined position on a main flow path through which liquid containing the microparticle flows, sucking the microparticle from the main flow path to a microparticle suction flow path by the microparticle suction flow path with a predetermined suction force, and counting the number of microparticles sucked into the microparticle suction flow path; and a step of determining an elapsed time from passage through the predetermined position with which the suction by the microparticle suction flow path should be performed
on the basis of a time from the time point when the microparticle passes through the predetermined position on the main flow path until the suction is performed and the number of counted microparticles.-

摘要： A fluorescence observation apparatus according to an embodiment of the present technology includes a stage, an excitation section, and a spectroscopic imaging section. The stage is capable of supporting a fluorescently stained pathological specimen. The excitation section irradiates the pathological specimen on the stage with a plurality of line illuminations of different wavelengths, the plurality of line illuminations being a plurality of line illuminations situated on different axes and parallel to a certain-axis direction. The spectroscopic imaging section includes at least one imaging device capable of separately receiving pieces of fluorescence respectively excited with the plurality of line illuminations.

摘要： Provided is a technology for increasing accuracy of a technology which optically detects characteristics of each of particles contained in fluid and analyzes or isolates the detected particles.
Provided is a particle detection device including a light applying unit that applies excitation light to a particle contained in fluid, a light detection unit that detects light emitted by application of the excitation light, and an excitation light detection unit that has an imaging element that detects the excitation light applied to the particle. The light applying unit of the particle detection device according to the present technology may be configured to apply multiple rays of excitation light having different wavelengths from different positions in a flow direction of the fluid. In this case, the excitation light detection unit can detect position information associated with the multiple rays of excitation light.-
