<P> Electron microscopes are used to investigate the ultrastructure of a wide range of biological and inorganic specimens including microorganisms , cells , large molecules , biopsy samples , metals , and crystals . Industrially , electron microscopes are often used for quality control and failure analysis . Modern electron microscopes produce electron micrographs using specialized digital cameras and frame grabbers to capture the image . </P>
