Spectrometer that carries out color measurements via detectors placed in such a way that enables measuring of different reflection angles from a colored surface. Goniospectrometers are used to measure colors that change at different angles, especially colors of coatings containing metal or pearlescent pigments.
An instrument that measures the color by dispersing the light coming from a colored surface to its detector by passing through a prism into its component wavelengths and determining amount of light ray at each wavelength. See Also Colorimeter
