läpäisymikroskooppi
Lävpäisymikroskooppi, known in English as a transmission electron microscope (TEM), is a powerful microscopy technique that uses a beam of electrons to image a sample. Unlike a scanning electron microscope (SEM) which scans the surface of a sample, a TEM transmits a beam of electrons through an ultra-thin specimen. The electrons that pass through the sample are then magnified and focused onto an imaging device, such as a fluorescent screen or a digital camera.
The resolution of a TEM is significantly higher than that of light microscopes, allowing for the visualization
TEMs are used in a wide range of scientific and technological fields. They are indispensable tools in
