Abstract
An illuminator includes a light source and an illumination optical system for causing light emitted from the light source to be incident on a sample surface where an imaging object is present. The illumination optical system has an optical axis coaxial with that of an imaging optical system. An image of the light source is formed between the illumination optical system and the imaging optical system. A holder arranges the sample surface between the light source image and the imaging optical system.
