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.

透射电子显微镜（英語： Transmission electron microscope ，縮寫： TEM 、 CTEM ），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。

透射电子显微镜（Transmission Electron Microscope, 简称TEM），是一种把经加速和聚集的电子束透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。

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.

2020年6月29日 · 几乎任何与材料相关的领域都要用到透射电镜，而最常用的三大透射电镜是：普通透射电子显微镜（TEM）、高分辨透射电子显微镜（HRTEM）和扫描透射电子显微镜 (STEM)。 本期内容介绍三者的殊与同。 重点解析在科研中如何适时的运用这三者？ TEM： 这里的TEM专指普通分辨率TEM。 其主要用来观察材料的微观形貌和结构，比如催化剂粉末的轮廓外形，纳米粒子的尺寸和形貌。 一般普通TEM的分辨率在几个纳米数量级。 下图1（多相粉末催化剂）、 …

2024年1月24日 · Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) are the two most common types of electron microscopy. TEM and SEM differ in how they work and what types of images they are able to capture. This article will overview SEM and TEM, including what they are, how they work, and how they compare to one another.

2025年1月25日 · The Transmission Electron Microscope (TEM) is a type of newer generation, high powered electron microscope. Essentially, the TEM “photos an object using a focused electron beam, resulting in high magnification and high detector imaging (over 2 million times that of a regular light microscope).”
