Invited review article: Methods for imaging weak-phase objects in electron microscopy

Contrast has traditionally been produced in electron-microscopy of weak phase objects by simply defocusing invited review article objective lens. There now is renewed interest, however, invited review article, in using devices that apply a uniform quarter-wave phase shift to the scattered electrons relative to the unscattered beam, or that generate invited review article image contrast in some other way.

Renewed activity in making an electron-optical equivalent of the familiar "phase-contrast" light microscope is based in part on the improved possibilities that are now available for device microfabrication.

There is also a better understanding that it is important to take full advantage of contrast that can be had at low spatial frequency when imaging large, macromolecular objects. In addition, a number of conceptually new phase-plate designs have been proposed, thus increasing the number of options that are available for development. The advantages, disadvantages, and current status of each of these options is now compared and contrasted.

Experimental results that are, indeed, superior to what can be accomplished with defocus-based phase contrast have been obtained recently with two different designs of phase-contrast invited review article. Nevertheless, extensive work also has shown that fabrication of such devices is inconsistent, and that their working lifetime is short.

The main limitation, invited review article, in fact, appears to be electrostatic charging of any device that is placed into the electron diffraction pattern. The challenge in fabricating phase plates that are practical to use for routine work in electron microscopy thus may be more in the area of materials science than in the area of electron optics. Abstract Contrast has traditionally been produced in electron-microscopy of weak phase objects by simply defocusing the objective lens.
