Abstract

A cell analyzing system flows a liquid to be tested and a sheath liquid through a flattened flow passage. An image of the flattened flow passage is formed at two different magnifications. The thickness of the liquid to be tested in the flattened flow passage is changed between the two different magnifications to maintain this thickness at a value smaller than a depth of field of the apparatus forming the image. The thickness of the liquid to be tested is changed by changing its flow relationship to the sheath liquid.
