Now wait a minute here. Looking at a nearby penny, I can measure the space between the pillars of the Lincoln Memorial. It's about 1mm. On the screen in the video, it's about 50mm between the pillars. That's only 50X and any half-decent USB microscope can do 50X just fine. You don't even need a good optical microscope. You use an SEM when you need 5000X or more; then they're worth their weight in gold (which is probably what that Zeiss costs).
Yeah, I’m not so sure that was the best demonstration they could have come up with. I was expecting to see a micron-sized wart on Lincoln’s nose or something.
Really, Lincoln sitting in the Memorial on the back of the penny is much clearer and better viewed with a magnifying glass that an electron microscope.
As a lab assistant I got to spend hours on an SEM photographing, or scanning thousands of leaf sections. I used to sneak in foreign objects to look at up close for my own amusement. I once put in a dead bee I found on the windowsill. I scanned its leg joints which was really cool. I'd even go as far as to say, it was the bee's knees (I made that corny joke back then too). I also scanned his eyelashes. Did you know bees have eyelashes? I did not. Did you know that a bee's eyelashes are conical and splined along their length? SEMs pick up insane detail. The intricacies of this mundane creature's body blew my mind. Fun times for a geek like me.
Yes! My stacks of pennies I go through in my change has me keeping really good strikes from over the years and I can clearly see far better detail with my reading glasses even.
For the record 2 nanometers its 0.002 microns. It also it would be interesting to hear if with this machine you have to dope the sample with metal or if it can also view organic matter without the need to coat the element.
@@JohnVance actually there are a few SEM units available now that use highly monochromatic electron beams that can approach a couple angstroms resolution, and are nearly capable of resolving atoms, such as Hitachi's SU9000II
Not easily - I imaged organic substrates in a very similar scope and you would get surface charging that would throw off the image. Sputtering just a little bit of platinum would fix it usually, but that could sometime mess up features.
I was thinking this was not such a great thing to use as an example of the capabilities of the machine. Even if you need some help, a 4x magnifying glass or the camera in a decent cell phone will show you Lincoln. My guess is that this was written by someone in the marketing department who doesn't really do math. They wanted something small but common and easily understood.
Sure, this isn't the most challenging test for a SEM, but it's relatable to something people are familiar with. What impressed me most was just how much information was conveyed without confusion and with so few words.
Almost all music on videos is sure to annoy some people, because no-one shares the same taste. Worse, the latest fad is extremely repetitive snippets of notes.
I spent about 40 years of my life looking at SEM screens, chiefly in failure analysis of aerospace and IC device failures. Invaluable tool, especially when combined, as is usual, with EDS.
When I was in high school I used to take the point of a compass used to draw circles and using a lens from a movie projector write love letters to my girlfriend on a penny. You couldn’t see any of it without a magnifying glass.
Support them how? I worked there for a couple years and it was awful! For every cool scientist you see at IBM there are a thousand other miserable engineers.

@@TALLPaul67X: Thanks, but I'm not sure how much of a point my question could be. Curiosity, though, yes. But what do you mean by "the die makes carved the coining stamp..."? Did you mean "makers"? Also, how did they have such small tools to manipulate the metal in the plates with?
That was interesting, Ty. A question for Mr. Ott. As photons are so much smaller than electrons and logically theoretically capable of much higher resolution, is there not an electromagnetic lens such as used with electrons that would work with electrons? If so, then the resolution and magnification would be orders of magnitude greater.
I learned to run an electron microscope when I was in graduate school - it was a blast. Zooming in on a sample is really fun. We had a sample of sand that we were trying to determine whether or not was from a marine deposit. We zoomed in on a single grain of sand until it looked like an asteroid, it filled the entire screen. Then I saw a small ledge on the side of the grain of sand, and we zoomed until the little ledge filled the screen and looked like a cliff. I saw a strange object on the side of the cliff so we zoomed in until the object filled the screen We had our answer, it was a fossil skeleton of a marine species of diatom, it had been waiting for us on a ledge on the side of a grain of sand for hundreds of thousands of years, where it had settled after dying in an ancient ocean, then we found it.
Yes you can! The rectangular device mounted on the right side of the electron column is Bruker energy dispersive x-Ray analyzer that is capable of detecting elements higher than Nitrogen! With this device you can generate x-ray maps that show the location of the detected elements.
Great video; very informative. It would be good to start off explaining why we need SEM in the first place as optical microscopes have a resolution limit because of the limitation in the minimum wavelength of visible light. Second, it merits mentioning that only electrically conducting samples can be imaged, making the penny ideal, but that PVD can be used to evaporate on a monolayer of a metal for nonconducting samples such as biological ones. Finally and most importantly, you should have taken an image of the *surface atoms* of the penny, not just stopped at the Lincoln Memorial statue that you can see in a standard optical microscope, and in some cases even the naked eye. P.S.: I think “anechoic” (pronounced “an-ek-O-ik”) was meant in the beginning, though it didn’t sound like that was what was said at all.
Lol you can see it better with the naked eye than that blurry grainy black and white rendering of what the laser thinks it sees. That's almost as bad as the NASA pictures. It's rendering from computer inputs I mean even just the quick regular camera shot of the penny gave you a much more focused and clear image.
The view of Lincoln was extremely unclear. I couldn't really see it even with it being pointed to and labeled. Is the copper-colored image from an optical microscope?
Should've used a proof penny, it would be a whole lot clearer and with less crud all over it. Could've looked at the tiny little VDB on his shoulder on the obverse/heads side, too.
Well, you did *always* need both to even be here with the penny and the rest of us. With you as a child, however, the photonic imagery you were fashioning upon your retina via your direct examination were from photons, but then the electro-chemical messages your retina gathers and sends down your optical nerve and into your brain most certainly uses electrons in its work.
Its pretty revealing the closer we look at man's engineering the more irregularities are revealed yet when deep diving into nature the more exquisitely complex they become.
I remember when the reverse was changed to the Memorial from the old laurel wreath. With bare eyes you could see not only the Lincoln statue but also the State names along the frieze. You should still be able to see that stuff if you catch one minted with a fresh die.
It has also been suggested that the states that were in the Union when Mr. Lincoln was in office were engraved on the one cent piece along the top of The Memorial.
@@davewinch7677 I can shoot pool like a master sometimes (click my name), but up close I need 4X reading glasses. Years ago I could see dust particulate in the valleys between my fingerprints at 3 inches from my eyes. Now, 'focus' does not even begin until 18 inches and that is out of true, sharp focus. But I snap multi-rail bank pool shots like a champ.
Right, I got my electron microscope at Wal-Mart, use it everyday. Glad to see that IBM's research dollars go to looking at pennies, improperly prepared for imaging. You can see Lincoln with just your eyes, and better with magnifying glass. Goo IBM.
I did a better demo with an optical microscope on our "bring your family to work" day a few years back. To demo the SEM, I showed voltage contrast imaging, which is very cool. You can actually watch gates of a chip turn on and off. Try that with an optical microscope.
Now what would be truly interesting is to take a penny straight out of a proof set and compare it to something that's been in circulation since back when you could reasonably buy things with them.
The most interesting thing I saw scanned was that of a Bee's eye. I used to design Ion sputter coaters, mostly used to cover biological specimens in a single layer of gold atoms over the sample to reflect the electrons.
I thought it was interesting that you had to use the microscope inside of an anechoic chamber. I’ve been in one and it can make you feel weird after a few minutes inside. I wonder how he can spend an extended time in there. The intense quiet isn’t for everyone.
Very good demonstration, Mr. Ott, now some questions: What version electron microscope did you use for the germanium project, that same one (model/brand) or an earlier one, and if you had used the one you showed us here would your work have been more effectively done or not? If you jumped up and down while scanning the penny a second time would we notice the distortion? Why doesn't IBM have a 'big blue' brand of electron microscope themself?
They invented the scanning tunneling microscope that can see atoms while I was working for them, but it was in the Zurich lab where they also won a Nobel prize for high temperature superconductors.
Nice video. I took electricon microscopy at University. Was my second favourite subject. Just a note, 2 nanometers is 0.002 microns. Slipped a decimal. No worries. Still love the video.
Never noticed that until just now. If you have 20/20, you might even be able to see it with the naked eye. My 20/20 started deteriorating around 2012, but my vision isn't too bad most of the time. If I need to read small print, a set of +1.50 reading glasses gets me through just fine. For small intricate work, I sometimes resort to +3.00. The oldest penny I looked at just now was a 1975, and I needed the small magnifier at the bottom of a $4 Walgreens magnifying glass. One of the more recent pennies that I could put my hands on without to much hunting, that still had the Lincoln Memorial on the reverse was a 2007, and I could just barely see the outline with +1.50 readers. It was much more defined with +3.00 readers, and even moreso with those readers and the small magnifier in the $4 Walgreens magnifying glass. One thing I wouldn't mind knowing... On the reverse, way off to the right, there appears to be something beside the steps. It almost looks like it says FG or 76. Can anyone either confirm or tell if it says something else? There's definitely something intentionally etched right there, because there is absolutely nothing beside the left side of the steps.
The most amazing thing I saw out of IBM labs is when they manipulated individual atoms (I forgot which element) to spell "IBM" under an electron microscope. Microchips also make interesting subjects for the electron microscope.

Exactly what I was going to say. Hey, you beat me to it.
I was gonna say- Yeah that ain't a very good image of the penny... what are we looking at???
Really, Lincoln sitting in the Memorial on the back of the penny is much clearer and better viewed with a magnifying glass that an electron microscope.
Exactly what I was thinking. The SEM made the engraving look muddy.

My dad got out a magnifying glass in 1959 to show a 10 year old me Lincoln in the memorial.
..was thinking he could see that with the ordinary microscope, surely..?

The Lincoln memorial penny came out in 1959. It was on every penny up until Lincoln's 200th birthday, and then a set of 4 commertive penny's came out.
As a lab assistant I got to spend hours on an SEM photographing, or scanning thousands of leaf sections.

Is there a video you could share demonstrating how to control writing on a surface that small? I am pretty curious to try it
As Feynman said, most problems in biology you could solve if you could just look at the thing
You can see the smaller Lincoln on a penny with a simple eye magnifier; you don't need an electron microscope.
Depends on your age ;•) 15 years ago I could see him fine. Now I need a lens.
