Chromatic aberration is related to the energy of the electrons. Electrons are not monochromatic. Electrons emerge from the gun at a whole range of energies.

The chromatic aberration causes a spread of electron beams on the focal plane of the objective lens due to the difference in the focal positions.

The fundamental effect of chromatic aberration (Cc) on TEM imaging is that electrons whose velocities differ from those with nominal velocity are diffracted ...

9 авг. 2016 г. · However, at the same time, the chromatic aberration deteriorates the resolution of the TEM image dramatically.

In transmission electron microscopy (TEM), chromatic aberrations in the imaging lens system can have a significant impact on the intensity distribution in the ...

As of 2024 both correction of optical as well as chromatic aberrations is standard in many commercial electron microscopes. They are extensively used in many ...

This phenomenon is called chromatic aberration. The energy spread of the electron beam arises from instability of the accelerating voltage.

The effect of chromatic aberration (CC) on the spatial resolution in transmission electron microscopy (TEM) was studied in thick specimens.

9 мая 2013 г. · Here, we use chromatic aberration-corrected TEM to record bright-field TEM images of nanoparticles in a whole mount macrophage cell. Tilt series ...

In this chapter, we begin by providing an introduction to the basics of spherical aberration-corrected imaging in the TEM. Very few liquid cell experiments have.
