A spectrophotometer including an optical measurement head, a spectrometer and a control electronic. The measurement head is equipped with a multi-channel illumination arrangement having exclusively light emitting diodes as spectrally continuous light source. Each illumination channel includes a light emitting diode, whereby each light emitting diode is separately controllable. In combination with the control electronic, an illumination with electronically adjustable spectral characteristics is hereby realized.
