ABSTRACT:
A flow imaging cytometer has an image capturing area for capturing the white-light image of a cell, and an image capturing area for capturing a fluorescent image of the same cell. The two image capturing areas are positionally offset from each other so that both images can be obtained in an excellent state with little mutual influence from the two types of light. Based upon detection of a cell using light from a light source for monitoring cell flow-through, a light source for exciting fluorescence and a strobe light source for emitting the white light area actuated after respective prescribed time delays. To this end, the cytometer incorporates a delay-pulse generating circuit serving as control means.
