Abstract
A colorimetry apparatus includes a light projection unit that irradiates a surface under measurement with light and an imaging unit that captures an image of the surface under measurement. The light projection unit includes a light source, a collimator lens that converts light emitted from the light source into parallelized light, and a traveling direction changer that changes the traveling direction of the parallelized light while maintaining parallelism of the parallelized light. The traveling direction changer is disposed in parallel to the surface under measurement, and the direction of the optical axis of the collimator lens coincides with the direction of a normal to the surface under measurement.
