Principle Of Transmission Electron Microscopy

Transmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through an ultra-thin specimen, interacting with the specimen as it passes through it.
It works on the principle of nature of electrons as they exhibit less wavelength when bombarded at high velocity.
An image is formed from the interaction of the electrons transmitted through the specimen; the image is magnified and focused onto an imaging device, such as a fluorescent screen, on a layer of photographic film, or to be detected by a sensor such as a charge-coupled device.

I don’t understand what you’re saying. You speak too fast.

Image in TEM is formed by the interference of elastically scattered and unscattered electors. It is not an absorbanece light dark fields image!
