Abstract
A spectral photometer intended for integration purposes includes a measurement head equipped with illumination arrangement including at least one light source for the illumination at an angle of incidence of 45.degree. of a measured object and located in a measurement plane, a pickup arrangement for capturing the measurement light remitted by the measured object at an angle of reflection of essentially 0.degree. relative to the perpendicular to the measurement plane, a spectrometer arrangement including an entry aperture for the spectral splitting of the measurement light captured and fed through the entry aperture, and a photoelectric receiver arrangement exposed to the split measurement light for conversion of the individual spectral components of the measurement light into corresponding electrical signals. It further includes an electronic circuit for control of the light source and forming digital measurement values from the electrical signals produced by the photoelectric receiver arrangement.
