Abstract
An imaging system using ultraviolet light or a manufacturing apparatus including the imaging system is provided. An imaging system includes an imaging element and a light source, which operates the imaging element with light that is emitted from the light source and reflected or transmitted by an object. A pixel included in the imaging element includes a photoelectric conversion element and a charge holding part. The light source has a function of emitting ultraviolet light to an object. The photoelectric conversion element is irradiated with the ultraviolet light reflected or transmitted by the object. The photoelectric conversion element has a function of changing the potential of the charge holding part when irradiated with the ultraviolet light and retaining the potential when not irradiated with the ultraviolet light.
