Abstract:
A measurement device includes a light source that radiates an illumination light on a measurement object; and a measurement unit that measures a measurement light that is reflection light obtained by the illumination light being reflected by the measurement object or transmitted light obtained by the illumination light passing through the measurement object. The illumination light is a plurality of illumination lights. In a case where the measurement object is positioned at a reference position, an illumination center at which an optical axis of each of the plurality of illumination lights and the measurement object intersect, and a measurement center that is a center of a measurement region of the measurement object measured by the measurement unit are positioned at different positions.
