Scanning electron microscope is a type of microscope that uses beams of electrons that are reflected to form images to scan the surfaces of mounted biological specimens. High resolution, three dimensional images can be obtained via the reflected beam of electrons. Thus, the electron scanning microscope is the perfect microscope for examining the contours on the surface of a bacterial cell.
