Transmission Electron Microscope
Revision as of 08:29, 22 March 2010 by 128.95.39.187 (talk)
The transmission electron microscope (TEM) is used in photonics research as a way of visualizing and measuring extremely thin layers. It is well suited for this research because the devices and prototypes are often conductive, are extremely thin, and can withstand high vacuum.
