1. A fluorescence reader (10) for a sample substrate (1) comprising:

  • a reaction site-surface (2);

    a substrate surface (3) opposed to said reaction site-surface (2);

    a light source (5) positioned to inject exciting light rays into the substrate surface (3); and

    a detector device (6) positioned to detect a fluorescent light emitted from the reaction site-surface (2) and transmitted through the substrate surface (3), wherein said substrate surface (3) is provided with a total-internal-reflection-suppressing means (12, 15, 16) located in an optical path of the emitted fluorescent light to increase transmission through the substrate surface (3) for detection by the detector device (6).
