Graphene Optical Lens a Billionth of a Meter Thick Breaks the Diffraction Limit (gizmag.com)
Zothecula writes: With the development of photonic chips and nano-optics, the old ground glass lenses can't keep up in the race toward miniaturization. In the search for a suitable replacement, a team from the Swinburne University of Technology has developed a graphene microlens one billionth of a meter thick that can take sharper images of objects the size of a single bacterium and opens the door to improved mobile phones, nanosatellites, and computers.
Wants her pico back!
they better get some superglue and put it back together before someone finds out.
This material seems to be the latest addition to Randall Munroe's long list of engineering problems that can be waved away by tacking on the prefix "nano-."

This would be huge for camera pills and colonoscopy cameras, imagine swallowing 3-6 camera pills (no bigger that a standard capsule pill) of these and they stream back a continue set of pictures as they travel from the mouth until they pass through the butt. This would be the shit!!!
People really ought to know by now that the word "billion" is ambiguous.
We have a perfectly good set of unambiguous SI prefixes.
One billionth of a meter = 1 nanometer = 0.000001mm

I am Slashdot. Are you Slashdot as well?
Science!!
I don't have anything else to say on the topic, it's just nice to hear about awsome stuff like this on a Monday morning. Sure, it isn't a flying car, but I'll settle for smaller colonoscopy cameras (as justcauseisjustthat points out above) just fine.
Come on, did the author not have room to fit in two words, "zone plate"?
Don't worry, soon they will add 3D printing and _then_ the word will be saved.
Great! I can have a better way to fix my vision without scary surgery. Seriously though, what would glasses be like with this tech?
I put the 'Physics' in 'Physical Attraction'
The wavelength of blue light is 400 nm.
Half a wavelength of blue light thus is 200 nm.
The article mentions the lens is able to resolve features as small as the diffraction limit.
Not which wavelength of light is used when resolving features as small as 200 nm.
Calling the ultra-thin lens diffraction limit breaking might be a bit premature.
eeeee ggg hhhh wowowow
What Rei said. We spend so much time (and by "we" I mean "people in the so-called First World but especially the U.S.") complaining about what we don't have, we forget how much we DO have, and what we HAVE accomplished — "we" in this case being "humanity." There's a lot to appreciate, which is why I like hearing about these advances.
Tell me about it - last week a dipshit from Greenpeace was educating me on how trees "decide" how much water they absorb by using Quantum!
Could this not be used for making smaller chips ?
How about Angstroms (Ã...)? Less ambiguous than billionth of anything.
Stupid /. adding an ellipsis.
Unless you are using the traditional English form of 'billion' in which case one billionth of a metre = 1 picometre.
This is less common and the use of 'meter', which in English is the spelling that refers to a device which measures rather than the length, suggests that it is written in American with the small billion but nevertheless as a previous poster pointed out a 'billionth of a metre' is ambiguous.
Are there any cool pictures this lens has produced yet?
Who will save the world first?
You sir are completely correct.
However... I wonder if you have ever heard of the run-on sentence?
Perhaps you have, since along with owning the grandparent poster, you have created a world class example of one.
Run on, right on :)
Given that the paper is in fact open access: http://www.nature.com/ncomms/2... ...
Why not link that in the summary instead of Gizmag's nonsense article ?
Also I'm confused. The paper says the lens thickness is 200nm. So where did the "1 billionth of a metre" come into it? From the paper: "a large size 200-nm-thick GO thin film is prepared on a glass substrate".
To address your question they show focused spots in wavelengths from the VIS-NIR (400-1000nm ish). The focus performance is pretty much constant throughout.
and here we have the spouting of another ignorant bigot.

Sweet! I'm pretty sure inhaling graphene microdust will prove to have no long term health effects.

I guess the War on Terror really is about freedom!
And apparently, if today's technology doesn't allow drunken fools to wipe out whole families by crashing into their vehicles from above, it's crap.
In other news, autonomous cars that may help with the drunk-driver problem are coming along nicely, thanks to... Science! Er, technology.
Reposting This from inside the debate -
This lens is the kind of thing that might lead towards nano-scale optical computing. And is also a potential small step towards the holy grail of tech - molecular scale assemblers.. Its even made of roughly the right material - grapheme - not such a large step from diamond composites...
Below the speed of light Special Relativity is one of the most accurate theories in physics - above the speed of light..

Yeah but what's still missing? Hoverboard!
False. You can get one for $20k.
