High Resolution Electron Microscopy: High Resolution Electron Microscopy is phase contrast microscopy of the atomic structure of materials. Specimen stages in these instruments are typically in the high-stability, top-entry configuration. An image intensified TV system allows the observation of the structure images on a TV screen prior to the recording of micrographs. Dynamic experiments are usually recorded onto video tape. A computer controlled image acquisition and analysis package is invaluable for the capture and storage of images of both on-line and off-line analysis and comparison with images calculated with multislice algorithims.
