Dr Tetsuo Oikawa, JEOL application specialist
Featuring the unique combination of high resolution electron optics and patented in-column energy filter, JEOL TEM have taken imaging of biological samples at ambient and Cryo temperatures a step further. For TEM imaging of biological systems Cryo temperatures have been used to reduce beam damage. In addition, Defocus Phase Contrast (DPC) has been used to improve image contrast. New methods of contrast enhancement have been developed and tested as the result of attempts to use conditions for more efficient imaging in Cryo EM. Those are based on devices that filter inelastically scattered electrons and/or modulate the electron wave and change its phase characteristics resulting in big improvements in contrast and visibility of various features of the specimen. The latest application data obtained using JEOL Omega filter and different types of phase plates installed in JEOL Cryo FE TEM will be presented and discussed.
