Together with researchers from the Max Planck Institute for Biophysics in Frankfurt, the Nano Technology Systems Division of Carl Zeiss SMT has developed a unique transmission electron microscope for the high-resolution phase contrast imaging of biologic materials. The PACEM system (Phase Contrast Aberration Corrected Electron Microscope) will enable artifact-free imaging of biologic specimens through the use of a unique phase plate and an aberration corrector, thus providing scientists unparalleled insights into the molecular and atomic structure of biologic processes and mechanisms of action. The development project is part of the Macromolecular Complexes cluster of excellence initiative and the introduction of elite universities in Germany.
