Abstract
A scanner device includes a color measuring, a support surface for a measured object and a drive unit for moving the measuring head across the support surface and for adjusting the height of the measuring head in a direction perpendicular to the support surface. The measuring head is equipped with an illuminating channel and a collection channel. The illuminating channel has a light source and optical means for illuminating the measured object at a measurement site at a mean angle of incidence of 45°. The collection channel has optical means for capturing light emanating from the measured object at the measurement site at a mean collection angle of 0° and coupling it into a light guide, which directs the captured light to a wavelength-selective photoelectric transformer, which resolves it into a number of wavelength ranges and generates an electric measurement signal corresponding to each wavelength range.
