Device for obtaining images of bacterial cultures in a dish

A device for obtaining images of bacterial cultures in a dish, including:

• a support (1) for culture dishes;
• at least one annular light emitting source (2) arranged around said support (1) for culture dishes, the light emitted by said source (2) being oriented in a direction not hitting said support (1) for culture dishes;
• at least one reflective surface (3) arranged facing said at least one light emitting source (2) for reflecting said light towards the support (1) for culture dishes, and
• a centered image capturing device (4), facing and spaced from said support (1) for culture dishes, for capturing images of a culture dish deposited on said support (1) for culture dishes;
• wherein
• the mentioned at least one reflective surface (3), in combination with a non-reflective surface (5), form a contrast observation chamber (6), in which a culture dish arranged on the support (1) for culture dishes is confined, the annular light emitting source (2) and the image capturing device (4) being integrated inside said observation chamber (6), and
• said non-reflective surface (5) is arranged in an annular manner around the image capturing device (4), superposed with respect to the support (1) for culture dishes and facing and spaced from same, said non-reflective surface (5) being provided with a surface finish with an albedo less than 0.4.
