Phase contrast provides the best means to high resolution electron microscopy images. The phase shifts induced by the light atoms that make up biological specimens produce very little contrast, which is why we usually image out of focus. This takes advantage of phase shifts introduced by the CTF at the expense of more complicated image processing, and loss of information near CTF zeros.

Phase plates offer a potential solution, but have been hampered by difficulty in use (Zernike phase plate) ... Más informaciones
