2023年4月22日 · An analytical method for visualizing microscopic structures is transmission electron microscopy (TEM). TEM can magnify nanometer-size objects up to 50 million times, revealing astonishing detail at the atomic scale in contrast to optical microscopes, which only use light in the visible spectrum.

2022年5月19日 · How does a Transmission Electron Microscope (TEM) work? The working principle of the Transmission Electron Microscope (TEM) is similar to the light microscope. The major difference is that light microscopes use light rays to focus and produce an image while the TEM uses a beam of electrons to focus on the specimen, to produce an image.

透射电子显微镜（英语：Transmission electron microscope，缩写TEM），简称透射电镜，是把经加速和聚集的电子束投射到非常薄的样品上，电子与样品中的原子碰撞而改变方向，从而产生立体角散射。散射角的大小与样品的密度、厚度相关，因此可以形成明暗不同的影像。

Transmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid.

Transmission electron microscopy (TEM) is used to produce images from a sample by illuminating it with an electron beam in a high vacuum. The electrons that are transmitted through the sample are detected to form an image.
