The theoretical resolution of electron microscopes is 0.23 nm for an accelerating voltage 100keV ( λ = 0.003701nm) and 0.12 nm for 300keV ( λ = 0.001969 nm) , and is mainly limited by the quality of electron optics.

Просвечивающая электронная микроскопия высокого разрешения — это режим визуализации специализированных просвечивающих электронных микроскопов, который позволяет напрямую отображать атомную структуру образцов. Википедия (Английский язык)
As the wavelength of an electron can be up to 100,000 times smaller than that of visible light, electron microscopes have a much higher resolution of about 0.1 ... |
The resolution is typically described as the distance between the first order peak and the first order trough (designated "r" above). Resolution is empirically ... |
High-voltage electron microscopes surpassed the 2.0 Å structural resolution limit in the early 1980s, enabling atomic resolution imaging for many ceramics, ... |
The authors estimate that the resulting resolution limit is in the range 0.5– 0.8Å, which is consistent with the best that has been achieved to ... |
In practice, the actual resolution of an SEM can range from 1 to 20 nm. Edge resolution (or knife edge resolution) is typically used to quantify the resolution ... |
Because our eyes can only detect photons with wavelengths greater than ~400 nm, the best resolution that can be achieved by light microscopes is about ~200 nm. |
SEM resolution is typically between 0.5 and 4 nanometers. Let us step back and explain how an SEM works, before we dive into the topic of SEM microscope ... |
The resolution of a light microscope is around 0.2 μm which can also be written as 200 nm. This means that it cannot distinguish two points closer than 200 nm. |
