Since the beginning of the electron microscopy, it has been well known that the phase contrast due to interference of the coherent wave plays a very important role in image formation. Distinctive examples are: Fresnel diffraction fringes as demonstrated by Boersch (1), Hisi (2) and others; interference fringes in crystals by Heidenreich (3) and Menter (

The Scanning Electron Microscope [PDF]
, 2005 As we discussed in Chapter 1, the scanning electron microscope (SEM) was invented soon after the TEM but took longer to be developed into a practical tool for scientific research. As happened with the TEM, the spatial resolution of the instrument improved after magnetic lenses were substituted for electrostatic ones and after a stigmator was added to ...

The Transmission Electron Microscope [PDF]
, 2005 As we saw in Chapter 1, the TEM is capable of displaying magnified images of a thin specimen, typically with a magnification in the range 103 to 106. In addition, the instrument can be used to produce electron-diffraction patterns, useful for analyzing the properties of a crystalline specimen.

A new electron microscope of greatly simplified design has been constructed. The instrument has a resolution of 100 Angstroms, yet is small enough to be mounted on a desk or laboratory table. Magnetic lenses are energized by permanent magnets. An accelerating voltage of 50 kilovolts is varied over a narrow range to provide means of focus. Images may be

Light microscope rivals electron microscope
Chemical & Engineering News Archive, 1993By combining a simple, low-power laser with a standard light microscope, scientists at the University of California, Berkeley, have created a "laserfeedback microscope" with a resolution that rival...

In this paper a transmission type electron microscope with magnetic lenses is described. The electron speed can be varied between 30 ekv and 100 ekv. The magnification of the instrument is produced in three stages. The instrument has improved air locks, hydraulically operated stage movement, and a stage tilting device up to ±15½°.
