A combination of electron microscope and optical microscope. The optical microscope is juxtaposed adjacent to the electron microscope so that the optical and lens axes of respective microscopes extend in parallel to each other. A specimen transfer mechanism is provided in common to both of the ...
Because the sample is imaged with electrons, rather than with photons in optical microscopy, no color information about the sample is communicated and images are presented in grayscale (Egerton, 2005). In a transmission electron microscope (TEM) (Fig. 1), the electron beam passes through the ...

Electron microscope, microscope that attains extremely high resolution using an electron beam instead of a beam of light to illuminate the object of study. Fundamental research by many physicists in the first quarter of the 20th century suggested that ca
Optical Microscope vs. a Scanning Electron Microscope Optical (light) microscope lacks resolution and depth of field when compared to the SEM. Thedepth of fieldis an important concept in microscopy that defines the portion of the image that is reasonably in focus [2]. In the example below, a...
the resolution of the electron microscope is much higher than that of anoptical microscope. The maximum magnification of the optical microscope is only approximately 1500 times, and the scanning microscope can magnify more than 10,000 times. The vacuum system in the instrument ensures the normal op...

The transmission electron microscope (TEM), the first type of EM, has many commonalities with the optical microscope and is a powerful microscope, capable of producing images 1 nanometer in size. They require high voltages to increase the acceleration speed of electrons, which, once they pass ...
1933: Ernst Ruska builds the first electron microscope that is more powerful than an optical microscope. 1935: Max Knoll builds the first crude SEM. 1935: Working at the University of Toronto, James Hillier and Albert Prebus build on Ruska's work to produce the first commercially successful TE...
