<p>A measuring head for the determination of the optical reflectance properties of color measuring fields co-printed with color sheets includes an optical illuminating device having two Mangin mirrors and an aplanar system located in alignment with the Mangin mirrors in a central opening. The light emitted by a light source and reflected by the measuring area arrives in a glass rod and is fed through an optical measuring device into a light waveguide, through which the reflected light is fed into a spectrometer for spectral analysis.</p> |
