Physical Principles of Electron Microscopy: An Introduction ...
The thin-lens approximation also simplifies analysis of the effect of the magnetic
forces acting on a charged particle, leading to a simple expression for the
focusing power (reciprocal of focal length) of a magnetic lens: 1/f= [e2/(8mE0)]
Bz2 dz ...

Handbook of Microscopy for Nanotechnology
Magnetic lens As in the electric case, an axially symmetric magnetic field also
has lens characteristics and is called a magnetic lens. The paraxial ray equation
for a magnetic lens is written as: d2r dz2 = q mrB20 8V (5) whereB 0 is the ...

Light and Electron Microscopy
Beyond the field limits, the beam again travels in a straight line, but it has been
deflected from its original direction according to the strength and extent of the
magnetic field.6 6.8.2 Action of the magnetic lens As shown in the preceding
section, ...

Scanning Electron Microscopy: Physics of Image Formation and ...
2.12 shows the combination of a conical magnetic lens and an electrostatic lens [
2.53-55]. The latter consists of an inner electrode at the acceleration potential
and an outer electrode at earth UoccO— . Magnetic lens Electrostatic lens ...

Istfa 2003: Proceedings of the 29Th International Symposium ...
Due to the design as a combination of a magnetic lens together with an
electrostatic immersion lens (Fig. 4), the aberration coefficients decrease with
decreasing electron energy (Fig. 4). This results in an ultrahigh resolution even at
very low ...

Intense Electron and Ion Beams
The matrix equation for the thick symmetrical magnetic lens coincides with the
one used for the thick symmetrical unipotential electrostatic lens. 3.10.3
Parameters of Some Magnetic Lenses Thin Coil The simplest magnetic lens is
created by ...

Handbook of Charged Particle Optics, Second Edition
When V2 equals V3, the excitation of the magnetic lens becomes NI = 1174 AT.
An interesting thing is that, this value is nearly the same as the excitation of a
TEM/SEM lens at 20 kV. When the same objective lens shape is used in a TEM/
SEM ...

Towards an Unambiguous Electron
Magnetic Chiral Dichroism ...
On contrary, also the stray field of the commutated objective lens system might
degrade the imaging quality of the microscope as the focal length of a magnetic
lens is finally defined by the magnitude of the magnetic field. To clarify this
question ...

Introduction to Conventional Transmission Electron Microscopy
The main purpose of a round magnetic lens is to focus the electron beam towards
the optical axis. The basic principle behind such a lens is shown in Fig. 3.3(a): a
circular current running through a coil produces a magnetic field that is nearly ...
