Who and when discovered the electron scanning microscope?
Charles Oatley in 1952 discovered the electron scanning microscope, but Max Knott created the first prototype of the SEM in 1935.
What is the difference between a transmission electron microscope and a scanning electron?
The Transmission Electron Microscope (TEM) was the first type of Electron Microscope to be developed and is patterned exactly on the Light Transmission Microscope except that a focused beam of electrons is used instead of light to "see through" the specimen. It was developed by Max Knoll and Ernst Ruska in Germany in 1931.The first Scanning Electron Microscope (SEM) debuted in 1942 with the first commercial instruments around 1965. Its late development was due to the electronics involved in "scanning" the beam of electrons across the sample. TEM focus a beam of electrons through a specimen while SEM focus a beam of electrons onto the surface of a specimen and the image provided is 3-Dthe transmission microscope magnifies 300,000 more times and the scanning microscope only magnifies 100,000 more the transmission gives the image of the inside and the scanning microscope gives a 3D image of the surface of the specimen

developers of the electron microscope
Who invented the light microscope and the electron microscope?
light Microscope: Zacharias Jansenn Electron microscope: Max Knott and Ernst Ruska and later improved by Vladamir Zworykin

Ernst Ruska and electrical engineer Max Knoll constructed the prototype electron microscope in 1931
who made the electron microscope?
Ernst Ruska and Max Knoll
In which year was transmission electron microscope was invented?
The transmission electron microscope was invented in 1931 by German engineers Ernst Ruska and Max Knoll.
Who is Max Knott?
Max Knott was a German scientist who co-invented the electron microscope in 1931 with Ernst Ruska.
When was the TEM invented?
The Transmission Electron Microscope (TEM) was invented in 1931 by German physicists Ernst Ruska and Max Knoll. They received the Nobel Prize in Physics in 1986 for their contribution to the development of the electron microscope.
Who discovered electron microscopes?
The electron microscope was invented by Max Knoll and Ernst Ruska in Germany in 1931. Ruska was awarded the Nobel Prize in Physics in 1986 for his contribution to the development of electron microscopy.
How far can a light microscope zoom in?
A light microscope can typically magnify objects up to 1000 times their original size. This level of magnification allows for the visualization of details down to the cellular level. Beyond this, electron microscopes are used to achieve much higher levels of magnification.
Was the electron microscope invented in Germany?
Yes. German engineers Ernst Ruska and Max Knoll built the first machine in 1931 in Germany. It didn't outperform the best optical microscopes, but it served to demonstrate the ideas. A couple of years later, Ernst Ruska (working for Siemens in one of their German locations) built an electron microscope that surpassed the resolution limits of an optical microscope. Wikipedia has a nice article on the history of the electron microscope, and a link is provided to that post. You'll find it below.
