What is a Transmission electron microscope / Transmission microscope / TEM?

A Transmission Electron Microscope (TEM) is a type of microscope that uses a beam of electrons to pass through a thin sample to observe its structure. TEM has an exceptionally high resolution compared to optical microscopes, allowing it to view structures at the atomic or nanometer scale. The electrons pass through the sample, and the transmitted electrons are captured to form an image. By analyzing the intensity and direction of the transmitted electrons, the internal structure of the sample can be observed with remarkable precision.

TEM is widely used in fields such as nanotechnology, materials science, life sciences, and chemistry. It requires samples to be very thin, so sample preparation can be complex and requires specialized knowledge and techniques. However, its high resolution allows detailed observations of cellular structures and atomic arrangements in materials.

The resolution of a TEM is orders of magnitude higher than that of optical microscopes, enabling the observation of atomic-level details like crystal structures and atomic positions. This makes it a crucial tool in scientific research and industrial applications, helping to detect tiny defects and anomalies that are invisible to other methods.
