- Television was cheaper and more easily set up; TV image-intensifiers were already in use for electron microscopes, X-ray machines, and other devices.†
Chpt 15 *electron microscopes = high-powered microscopes that uses electrons instead of light
- To obtain higher magnification, they would have to go to a separate room, or else use the electron microscopes.†
Chpt 15
- He had not used an electron microscope for nearly a year.†
Chpt 15electron microscope = a high-powered microscope that uses electrons instead of light
- He removed the internal organs from the rat and monkey and examined each, removing samples for both the light and electron microscopes.†
Chpt 16electron microscopes = high-powered microscopes that uses electrons instead of light
- The electron microscope was a valuable tool, but occasionally it made things more difficult, not easier.†
Chpt 16electron microscope = a high-powered microscope that uses electrons instead of light
- The electron microscope could provide great magnification and clear detail—but only if you knew where to look.†
Chpt 16
- That was how thick they wanted a slice of tissue to be for the electron microscope.†
Chpt 22
- Finally, the button was set into the electron microscope, and the microscope sealed shut.†
Chpt 22
- The electron microscope used by Wildfire was the BVJ model JJ-42.†
Chpt 22
- In principle, the electron microscope was simple enough: it worked exactly like a light microscope, but instead of focusing light rays, it focused an electron beam.†
Chpt 22
- The great advantage of the electron microscope was that it could magnify objects far more than the light microscope.†
Chpt 22
- In the same way, an electron microscope will 'hold the road' better than a light microscope.†
Chpt 22
- But an electron microscope can follow all the minor routes, the byroads, and can outline very small structures within the cell—mitochondria, ribosomes, membranes, reticula.†
Chpt 22
- In actual practice there were several drawbacks to the electron microscope, which counterbalanced its great powers of magnification.†
Chpt 22
- Limited as it was, the electron microscope was their only available high-power tool.†
Chpt 22
- An electron microscope could outline small structures within the cell.†
Chpt 22
- It was not, in this sense, a microscope, and it operated differently from either the light or electron microscope.†

Definitions:
-
(1)
(electron microscope) a microscope that uses electron beams rather than light, achieving much greater magnification and revealing structures at the molecular levelDeveloped in the 1930s, electron microscopes can magnify objects up to 10 million times—far beyond light microscopes' maximum of about 2,000 times. This is possible because electrons have much shorter wavelengths than visible light. Electron microscopes have revolutionized biology and materials science, revealing viruses, cell structures, individual molecules, and even atoms. However, unlike light microscopes, most electron microscopes require specimens to be in a vacuum and cannot image living samples.
- (2) (meaning too rare to warrant focus)
