<p>As an example of the disclosed reflectance property measurement device, a color density meter (10) is provided with: a polarizing plate (5a); and a phase-shift plate (5b) that is disposed between the polarizing plate (5a) and a sample surface (1s), and wherein the sum of the phase change of a transmitted illumination light beam and the phase change of an incoming light beam is 1/2 wavelengths. As a result, the color density meter (10), as an example of the reflectance property measurement device having this kind of a configuration, is easy to handle, has a compact configuration, and can measure reflectance properties from which surface-reflected light has been eliminated or added.</p> |
