Is transmission electron microscope the original EM, and Scanning the better resolution one. What is the main difference between the two
TEM was the first form of electron microscopy (the invention won Ruska his Nobel Prize). It also has a better resolution than SEM.kevin86 said:Is transmission electron microscope the original EM, and Scanning the better resolution one. What is the main difference between the two
That's STM you have in mind, not SEM.NoTime said:I suppose you could say Scanning uses quantum tunneling electrons while the TM uses clasical electrons.
An electron microscope is a scientific instrument that uses a beam of accelerated electrons to magnify objects at a much higher resolution than a traditional light microscope.
An electron microscope works by using a beam of electrons instead of light to magnify an object. The electrons are focused and accelerated towards the object, creating a highly detailed image that can be viewed on a screen or photographed.
The main advantage of using an electron microscope is its ability to produce images with a much higher resolution than a traditional light microscope. This allows scientists to see smaller details and structures in the object being viewed.
An electron microscope can be used to observe a wide range of objects, from cells and tissues to microorganisms and nanoparticles. It is also commonly used in materials science to study the structure and composition of various materials.
While an electron microscope has many advantages, it also has some limitations. It can only be used to observe non-living objects, and the preparation of samples for electron microscopy can be time-consuming and complex. Additionally, electron microscopes are expensive and require specialized training to operate.
