Under the Microscope: A Hidden World Revealed
Lenses for light microscopy consist of many pieces of glass differing both in
refractive index and shape; by altering these two variables, the lens designer is
able to overcome aberrations and produce a lens of chosen An electron lens
consists ...

2.2.1 Electron Trajectories in a Magnetic Lens Field The physical background of
electron-lens optics will be described only briefly to give a quantitative
understanding of the function of an electron lens (see [2.2, 2.3, 2.4, 2.5, 2.6, 2.7]).

The Principles and Practice of
Electron Microscopy
In an electron lens «= 1 and a is small enough to be equated to sina. The
diffraction limited resolving power is thus </0=0.6A/a, and for the best resolving
power a should therefore be large. In order to balance the requirements of the
two ...

(b) Use of an electrostatic stigmator to correct for the axial astigmatism of an
electron lens. Axial astigmatism also occurs in the human eye, when there is a
lack of axial symmetry. It can be corrected by wearing lenses whose focal length

The flux can be further concentrated by including a ferromagnetic (iron alloy) core
, and a central bore, through which electrons can travel, converts the device into
a primitive electron lens (Figure 6. 1 Ic). Such a lens would be of minimal ...

Of course the analogy with light fails for certain aspects, but basically it will
pervade this chapter. So we'll start by reminding you of the principles of light
optics insofar as they relate to electron optics. Then we'll discuss the electron
lens in more ...

Electron Microscopy of Polymers
an electron lens varies with the energy of electrons. Thelens bends electrons of
lower energy more strongly, and thus electrons from a point in the object once
again form a disc image in the Gaussian image plane. The radius rc of this disc is

3.1.3 Electron Lenses Electron lenses are quite different from optical lenses: an
optical lens is usually made of glass, whereas an electron lens uses
electromagnetic fields. This is because electrons cannot pass through thick glass
