A system for the characterization of a colony of microorganisms includes a coherent light source configured to provide coherent light of one or more wavelengths along a common optical path. A holder is configured to operationally arrange a substrate so that the colony of microorganisms on a surface of the substrate is positioned to receive the coherent light. Scattered light is generated from the colony of microorganisms receiving coherent light. A first image capture device is configured to receive the scattered light and generate a scatter image from the microorganism colony irradiated by the coherent light. The system also includes a magnifying lens configured to magnify the colony of microorganisms. A second image capture device is configured to capture a light image of the colony of microorganisms magnified by the magnifying lens. Methods of assigning organisms to categories with like organisms without necessarily identifying the organisms are also described.
