Abstract
An irradiation optical system configured to irradiate an object with first light includes: a light source including a surface emitting element emitting the first light from a light emitting surface; a light shaping member on which the first light emitted from the light source is incident via a light incidence surface and which shapes the incident first light using a light passing hole and emits the shaped first light; and a first lens configured to form an image of the first light emitted from the light shaping member on the object. A distance between the light emitting surface of the surface emitting element and the light incidence surface of the light shaping member is equal to or less than 26 times a size.
