A biochip reader for qualitative and quantitative analysis of images, in particular for the analysis of single or multiple biochips with different colorimetric signals for different targets of biological interest such as drugs or nucleic acids, fat acids and proteins from viruses, prokaryotes and eukaryotes organisms, obtained from human, animal, vegetal or environmental biological samples. Said biochip reader comprises: - an optical head 18, able to moving itself in one direction Y, comprising: - at least one visible light source 20 or 21 - at least two CCD sensors 16 and 17, attached each other; each CCD comprising a reflective lens set 24 and a focalising lens 25; - control means, able to control said optical head 18 and its one-dimensional motion. Being each CCDs attached each other, then each half, or portion of, image has an identical position or angle error of the other half, or portion of, image, so as the joining process becomes immediat
