Abstract
A spectral colorimetric apparatus for detecting a color of an image of a test subject illuminated includes a stop; a spectral detection optical system for spectrally detecting a beam diffused in the test subject and passing through the stop; and a guiding optical system for guiding, toward the stop, the beam diffused in the test subject, wherein in a first section which is a section including an optical axis of the guiding optical system, condensing positions of the light beam condensed by the guiding optical system change depending on a position in a direction orthogonal to the first section, and the stop is disposed between condensing positions closest to and farthest from the guiding optical system, of condensing positions, in the first section, of the beam condensed by the guiding optical system, in a direction of the optical axis of the guiding optical system.
