Abstract
An imaging device includes a prism that separates visible light and fluorescence included in light from a target to be observed, a visible-light imaging sensor that captures the visible light separated by the prism, and a fluorescence imaging sensor that captures the fluorescence separated by the prism, in which a ratio of a pixel spacing in the fluorescence imaging sensor to a pixel spacing in the visible-light imaging sensor is 1 or more and less than 5.
