When digitizing with planetary scanners, the margin area of the documents is of crucial importance.
Experience has shown that the sharpness of scans decreases towards the edge. Special lenses are therefore needed to ensure that documents and originals are uniformly sharp across the entire imaging area, i.e. not only in the center but also in the critical edge areas.In addition, distortions or color fringes sometimes occur in the peripheral areas.
To prevent this, all our systems are equipped with apochromatic corrected industrial optics designed specifically for digitization.
