Fluorescence imaging device for microbiology has laser illuminating structure with mixture in micro-channels and reader including micro-lenses and linear charged coupled device camera

摘要

A fluorescence imaging device having a laser illuminating a structure (4), micro-channels holding a mixture of substances and a reader for the fluorescence produced by the material. The reader includes micro-lenses (7) and a linear charged coupled device camera (9). A wedge is between the reader and the structure. The incident laser light is perpendicular to the structure. The structure is a glass block 40 mm long, 15-20 mm wide and 3 mm thick. Its micro-channels are parallel to its length and 500 microns long, 500 microns thick and spaced 700 microns apart. The reader has 1-3 layers of micro-lenses and an optical filter layer (8). A diffractive matrix is between the wedge and the lens layer.
