I'm amazed they can see the image in real time. I always imagined the image taking extraordinary long amounts of time to process.

[sonicrising]

It blows my mind that somebody figured all this out.

If theres ever an apocalypse im just gonna break into a lab with one of these and play around until i get killed

Great video. I actually ran one quite similar back in the early 1980's while working at a semiconductor manufacturer in San Jose - on Bubb road near Deanza college. I took step coverage micrographs of mil-spec parts along with the occasional insect. Wolf spiders up close have really big fangs! and bees eyes are incredible. But you need to be very careful or you can set them on fire and really mess up the internals - takes hours to clean and re align the collumn.

best explanation of electron microscope on youtube

[leopardtiger]

Clear very good explanation. Thank you. I used SEM in 1969 at RWTH Aachen for my Doktor work to study surface of iron ore after reduction with CO and H2. It revealed iron whiskers in different shapes and sizes and explained reason for abnormal swelling during reduction. Though I used it in 1969 today I understand with more clarity how SEM works from your video. Thank you.

[BangMaster]

A great explanation for people without Engineering degrees. Thank You

8:46 When your nearly $1, 000, 000 scanning electron microscope is run by Windows 3.1, LOL.

[larrykent]

Thank you for the fine job explaining the basics of how a scanning electron microscope works, including the great pictures. Cheers!

[millionpercocetplease]

Never would've imagined the microscope is moveable and magnifyable in real time. Holy shit.

[mstepansky]

Electron scanning microscope reminds me of a very similiar concept: like an upsided down vaccum electron tube, as in TV scanning cathode ray tube, but with more complicated controls inside to examine the specimens on the plate. Thanks to quantum mechanical physics!

[edward_grabczewski]

very nice and clear presentation. The metal analysis section was a nice bonus!

[arnavkatepallewar]

The finest and exact explanation of working of an electron microscope ever!

[ThMafia]

i have waited too long to watch this video, only found it just now, great presentation of information!! thank you

The non-destructive chemical composition detection due to the type of emitted x-ray is freaking brilliant. Pieces of the puzzle become illuminated once you begin to construct the picture.

[rasmussenrambles]

I've seen one been used in real time
It is absolutely mind blowing

[muffinman]

6:33 On the surface of the weld, it looks calm and ready.

[thangkhiam]

well explained, sir. easy to understand, very good resolution n very systematic operation!

[davidlloyd]

I worked with an SEM as part of my microbiology degree. Brilliant piece of kit.

Beautifully illustrated and awesomely shown.
