Abstract
A spectrophotometer for integration purposes includes a measurement head with an illumination arrangement (10) including at least one fight source (11) for the illumination of a measurement object located in a measurement plane (M) under an angle of incidence of at least 45°, with a pick-up arrangement for capturing the measurement light remitted by the measurement object under an angle of reflection of the essentially 0° relative to the perpendicular of the measurement plane, a spectrometer arrangement (30) with an entry slot (31) for the spectral splitting of the measurement fight received through the entry slot and captured and with a photoelectric receiver arrangement (32) exposed to the spectrally split measurement light for conversion of the individual spectral portions of the measurement light into corresponding electrical signals.
