Abstract

This flow cytometer includes a flow path through which an observation object flows with a fluid; an optical illumination system including a spatial optical modulation device, and a first optical element; and an optical detection system including a first light detector, wherein the optical illumination system further includes a first spatial filter disposed in a first optical path between a light source and an image position of light imaged in the flow path by the first optical element and having a first region which hinders traveling of light emitted from the light source towards the observation object, the optical detection system further includes a second light detector disposed in a second optical path between the first light detector and the image position and having a second region which directs the light modulated by the observation object towards the first light detector, and the position of the first region and the position of the second region are in a substantially optically conjugate relationship.
