Light microscopes let us look at objects as long as a millimetre (10 - 3 m) and as small as 0.2 micrometres (0.2 thousands of a millimetre or 2 x 10 - 7 m), whereas the most powerful electron microscopes allow us to see objects as small as an atom ( about one ten-millionth of a millimetre or 1 angstrom or 10 - 10 m ).

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 ... Transmission electron · Scanning electron · Electron optics · Electron diffraction |
The limit of resolution of a TEM is now less than 1 nm. The TEM has revealed structures in cells that are not visible with the light microscope. |
As the wavelength of an electron can be up to 100,000 times shorter than that of visible light photons, electron microscopes have a higher resolving power that ... |
Practically, the resolution is limited to ~0.1 nm due to the objective lens system in electron microscopes. |
23 окт. 2024 г. · Electrons have a smaller wavelength than visible light and therefore allow higher-resolution imaging of features as small as 0.1 nm. |
An electron microscope is a microscope that uses a beam of accelerated electrons as a source of illumination. |
