An optical analyzer, configured to receiving a cartridge for biochemical analyses including a plurality of wells, and carrying out fluorescence analysis of the cartridge, in particular of the wells. The analyzer comprises a control unit (microprocessor and memory) configured to: (a) acquiring an image associated to the fluorescence emitted by the cartridge; (b) identifying, in the image, pixels belonging to boundary lines of the wells by generating a black and white binary image; (c) recognizing, between the geometrical shapes identified in step (b), the ones that best approximate a reference geometrical shape identifying an ideal well; (d) acquiring, from the starting image, values of light intensity only in portions of the image itself that in turn correspond to the regions recognized in step (c); and (e) evaluating a state of advance and/or a result of the biochemical analysis on the basis of the values of light intensity acquired in step (d). |
