By now, Ken and his companions had learned the use of the electron microscope and how to prepare specimens for it.
He set the electron microscope up on that and plugged it in.
The electron microscope told them that, now that they had the substance isolated and could examine it.
The screen was a cubical frame in which an apparently solid image was built up of an object under an electron microscope.
I'll arrange for one of the teaching fellows to show you how to prepare metallic samples and operate the electron microscope.
It took an electron microscope to do it, but he found a virus in the blue patches which matched the type discovered on Tralee.
He found his father in the laboratory working with the electron microscope.
She touched the electron microscope with something like affection.
electron microscope n.
Any of a class of microscopes that use electrons rather than visible light to produce magnified images, especially of objects having dimensions smaller than the wavelengths of visible light, with linear magnification approaching or exceeding one million (106).
|electron microscope |
A microscope that produces images of extremely small objects by using beams of electrons rather than visible light. Since electrons have a much shorter wavelength than light, the use of electron beams rather than light beams can resolve much finer structural details in the sample. Electrons are beamed at the sample and focused by magnets; a detector then converts the refracted or reflected beams into a black and white image. Powerful electron microscopes can create accurate images of objects as small as individual molecules. See also scanning electron microscope.
