book2net has developed a novel method for multispectral analysis of documents and drawings. Single or series of scans can be performed in definable nm intervals. The scan results can be superimposed with pixel accuracy for anlyzing. The book2net system works without changing filters (i.e. vibration-free) and without post-correction of sharpness and focus in the spectral ranges (i.e. pixel-scale accurate).
