Unlike traditional lenses, metalenses are flat and made of silicon with intricate patterns etched into them. These patterns allow precise control of light, enabling new possibilities in imaging and sensing.
Metalenses can see through glare, haze, and even black ice, and can also be used for identity verification, detecting artificial faces, and recognizing cancerous skin growths.
The manufacturing process for metalenses is similar to that of computer chips, making them smaller, cheaper, and easier to mass produce. As metamaterials become more widely available, they are set to revolutionize mobile devices, cars, and medical technology, transforming how we observe and interact with the world.

This company should make their mascot/logo for this lens the rainbow mantis shrimp because these animals can also see all the types of light and polarization that this lens can.
That would be cool
And their compound eyes look a bit like these wafers.
odd, but I would agree! lol!
Merely binding them into some conservation and outreach activities yaaaay. They cured my testicular cancer yay ow ow ow ouch whoo...
They are fooling and enslaving you with these gadgets 👉 The Connections (2021) [short documentary] 💖
this is the kind of technology that motivates me to live longer
👴❤️
When taking physics in undergrad and thinking about how to make space telescopes that can image exoplanets. The idea of a lens that can capture all the information contained in the photons in a nanometer size region space would allow this but until now I had no idea they actually had something that can do this. This would enable the mass production of a fleet of telescopes that can collectively image incredibly small and far away things.
They are fooling and enslaving you with these gadgets 👉 The Connections (2021) [short documentary] 💖
Omg i completely forgot about this part.
Imagine if we could put a big one for those telescope we sent above. This would be massive, we already invented something better than JW that was supposed to be the best we had
There's already talk of using the sun as a gravitational lens to magnify a point far behind it in the same way we get gravitational lensing in deep space images. If one could someday locally manipulate gravity, one could focus the light to a small point made of meta-lenses and extrapolate a ridiculous amount of information that we'd never be able to see without physically being there.
sadly, you'd still need X amount of photons, which would require a _huge_ collection surface for this kind of project. I doubt that inferometry based optics would be more efficient in "collecting" light than a plain mirror? An interesting idea for this project is to use the sun as a gravitational lens. There is an interesting paper from JPL on this, presented by this "friendly neighborhood astronomer Prof. of astronomy youtuber", forgot his name though...
Astronomy was the first application I thought of as well. The metalenses could conceivably detect virtually everything across the entire light spectrum without the need for sub zero cooling.
I've been dreaming about metalenses for years. This is the holy grail of the lenses and it will be a revolution in smartphone cameras.
Magic Leap's CEO often talked about their waveguide being an "optical processor" (might be misremembering the exact term used). So a much more impressive use than the camera of a smartphone, would be for optical computing. When using photons, there's a MUCH larger processing bandwidth achieved due to the different wavelengths can use independent of each other. The different pieces have been slowly being developed for a while now, and hopefully can soon be brought together.

That's great over 9 billion phones in the world NOT ONE IN MADE IN AMERICA, CELEBRATE THAT.
@@c123bthunderpig why don't you make one then
@@Skinflaps_Meatslapper I have, not just one but by the billions for over 30 years, nothing new here, American industry shut it down, sent it off shore , killing jobs, and making more profit, not to mention giving away intellectual property in the meantime.
I, and many others, were making these routinely in our labs in the late 1980s. There are many published papers on the subject. My first Ph.D. student went on to found a company that sold these commercially in the 1990s. If Metalens has any advance over old technology, it's not apparent from the video.
Lately I've been wondering if the sort of tech used in phased array radars and to steer wifi/cellular beams is applicable to visible light. What i'm wondering is this mostly based on the same principle?
This video and the company's website present it as an obscure new technology... from what I understand, this is a holographic lens, holograms were invented in the 60s and have to be made on photographic plates, the real innovation here is to make the hologram using photolithography.
Another possible innovation is to control both the amplitude and phase of the interference pattern, making this an in-between of holograms and spatial light modulators, and would allow to remove the conjugate image.
The big problem is that such a lens can only work with a single wavelength of light and can only be used with laser illumination.
Could be used for machine vision applications, but it's certainly not going to replace camera lenses anytime soon.
The video illustrates the patterns of the lens with tiny colored shapes... nope, the pattern is probably concentric circles, what is called a fresnel zone plate.
@@xstrxd Yes, it's called a hologram, and it's sort of an optical phased array. The "beam-steering" properties of holograms allows them to record images of 3-dimensional objects. Holograms were also used in the 60s and 70s to reconstruct images taken by radar satellites
Well, what happened? You sound scornful.
It might be an ad for the company targeted at investors.
one thing they did not touch upon is that these lenses can be made in a way that makes photonics possible i.e. computing with light instead of electrons.
Isn’t that in a way less efficient since Light wavelengths can be way larger than using electrons?
@@mancerrss
That doesn't matter here
@@mancerrss BUT, the computing would be done at the SPEED of LIGHT.
AND, you could EASILY...... Increase the size of a BYTE!!!!
have bytes of 8, 16, 32, 64......
OR, 10, 20, 40, 80, 100 or 200, if you like!!!!!!!
How would these lenses be better then fibre optics? Explain to me
@@Player-pj9kt
the same way an integrated chip is better than a circuit made of copper wires: circuit elements can be packed into microscopic sizes thus having every bit of area contain more circuit elements leading to greater compute power for the same area.
Optics only get so complicated because we need more optics to correct for the faults in the original optics, but even the correcting optics themselves need correcting. You just can't win. Meta lenses don't need any of that and that makes them simpler and much better.
I know vr headsets get around this problem by making sure the inconstancies are consistent and then corrects it digitally.
Hubble telescope has left the chat.
@@mcmadness110 That only works for problems like chromatic aberration. You still need optics to correct for spherical aberration. You still need to have it full in focus on the LCD plane.
This is the reason why Arri Sig Prime lenses has to be that huge.
They got a correction piece of glass for the correction piece of glass for the correction piece of glass and so on haha
That near perfect no focus breathing is unreal.
But as they stated, it's still not 100% perfect, just enough and look the best with our eyes.
Wait for this semiconductor level lenses etching for the phone to be cheap and mass produce. probably nice to have apsc size sensor on phone with lenses like 2 mm thick and got 24mmF2 FF equiv.
If not, at this rate, we probably got the phone that has 10 cm thick camera bump lmao.
A telescope built with these would be fantastic, since CMOS image sensors and meta lenses are both made via photolithographic processes you could feasibly order multiple wafers and make them a bunch of self contained units. Each one a mini telescope. Then package them in into a VLBI orbital observatory.
Also I'm not sure about the maximum angle, but since silicon is invisible to some IR, you could make a Sensor + support-silicon + metalense stacked die for very small cameras?
Light doesn't scale. When it comes to cameras and lenses (or optical mirrors) there is no substitute for size.
This video is exactly correct when it emphasizes that it offers extracting more information _inside_ the image. That is also all it offers. But we don't know yet what that will lead to. Better identification and diagnosing probably, that sounds very plausible. Military AI that is better at discerning the hiding russian soldiers it will plink with mini grenades, maybe.
Having AI machinery to 'see' more will maybe be the biggest application.
My guess is that the polarization detection will offload a very big portion of an AI's work when it tries to see 3d... Computer vision would become more reliable, and if it can see more than a human, the possibilities for it are endless.
@@Vermiliontea Though I agree, it would have an effective military application, it is still a weapon politicians are gonna use for mass slaughter. Those fuckers want you to think they are protecting you, they will do everything possible to paint themselves in a good light, even though they have instigated those wars themselves to further their agenda. And I'm not defending Russia, rather, USA has the same fault in what is happening. I wonder if USA wins, who is the next bitch they will harass? China? They talk about free market, yet for them destroying the lifeblood of other countries is also "business". In short, be careful of what you're supporting, for I am sure that you know not all the underlying consequences.
@@Vermiliontea if we can capture light by multiple sensors preserving the coherence by for example, mixing it with the reference source like laser, it would allow to build a facet eye telescope from multiple cheap units
That little jab at Zuckerberg 😂😂😂😊
Outstanding, amazing tech. A true paradigm shift. Congrats to the chefs. Bring it on.
Interesting subject, informative, well produced and top tier animations. Appreciate it!
Meta-materials will change our world, and how we look at it.
This specific tech, can also be used as a magnifier to see both the very small, and the very far. I Love how this can be used to 'see' much broader wavelength as well.
Light bending meta-materials for cloaking has been tested for at least a decade.
Meta-matrials can be used for most, if not all wavelengths, enhancing things like antennas and sensors.
In a way, we have been using such materials for decades already. DLP, lab on a chip, the microscopic sensor that detects acceleration in everything from your car to your cellphone.
As you could see, this was made in a fab. Only our imagination limit what kind of 'machines' we can shrink down on to a microchip...
Fantastic I'm waiting for this for years!
This technology I can see is gonna be absolutely, and not only this gives cameras and optics and sensors etc more capabilities including making them even more powerful and things that we never thought possible I'm very excited for this technology
Incredible video, had never heard of these materials before but there's a lot of room for growth if they're being printed in the same way as processors.
this video is fraudulent and so is the company this video is about. americans have no intelligence or integrity. change will not come from america.
It is one of my first time watching Freethink and I love the « Hard Reset » technology forward looking concept ❤.
I like very much video about optical meta-optic through photolitography and this video conveys exactly what I am thinking about this technology for a long time (after reading an article on Technology Review).
In my opinion, another interesting topic is spintronics and MRAM (let say bi-stable DRAM, like be-stable E-Ink displays) that should finally allow « Normally-off Computing » to emerge.
The European research center IMEC recently published work about their Non-Volatile VG-SOT-MRAM and Intel is also working on their beyond CMOS technology concept called MESO…
So glad you liked the video! We have more Hard Reset episodes coming soon, so keep an eye out. Really interesting topics you posted, too - we'll check them out!
This is like a phased array antenna but optical. Very cool.
This is really exciting! I‘m really thrilled to hold one of these sensors in a consumer product for the first time
such a great channel. you have gained a sub!
These will revolutionize so many things, including contact lenses, microsatellites, medical imaging, photonic computing, so much
Wow! 😮 Loving the CGI light passing through lenses!
This entire video comes off as an advertisement masquerading as education. It's very well produced, with super crisp visuals, and smooth editing. It also stretches out every simple explanation by 10x, and is pretending like this tech is new, when it's not. You can watch Huygens Optics make these things in his garage shop, and he walks you through all the actual science + the software used to design these lenses.
Agreed, this feels very "solar freaking roadways". Not to mention the infantile talk, this is for a specific target audience.
In which video did hyguen optics make these lens? I dont recall him using photolithography to create an array of lens. The new manufacturing technoque is the topic of this video
Yeah, this is cringe AF and I cannot watch it.
that's really cool!, the explanation of the fingers in the water interfering with the waves was actually very helpful. It gave me a good intuitive, if very basic, understanding of how they work
Interesting subject, informative, well produced and top tier animations. Appreciate it!. Interesting subject, informative, well produced and top tier animations. Appreciate it!.
Glad you enjoyed it!
Amazing tech... congratulations! SCARY what can be done with this tech
The Carl Sagan is going to truly be next level. Cant wait.
This is awesome. The future is exciting.
One thing....vacuum tubes are NOT transistors...they can perform the same functions but transistors are solid-state devices allowing the miniaturization that results in innovation in electronic design.
It might be used to transport data with huge bandwidth potential, and depending on sensors possibly store it.
Insane graphics, very informative. Thanks for the video
Ok can manipulate light. but how clear it is? can be used in eye glass or camara lens?
1:04 you had me at “you could change your wife”
Polarization is so cool, I did not know this is what polarization could tell as I found it counter intuitive.
Where do I get one of those vacuum tube transistors?!? 🤣
Never-the-less, this is revolutionary!
This will unlock so many possibilities that people haven't even dreamed of yet = we can only think of X uses for it
I like the Automotive Application benefits. Whether people use them or not (idc how good of a driver you are, the computer thinks faster) Pre Collision Auto Braking, Collision Avoidance, Lane Keep Assist, Adaptive Cruise, Blind Spot Detection, etc. all things that help bad drivers be safer for others, and avoid accidents. A black ice sensor would be amazing in Winter areas.
Truly amazing 👏
Basically you can have a 4cm diameter lens on your smartphone, and throw your DSLR camera in the bin
i do not think thats what they can do , it thins but i do not believe aperature is a thing they can claim to have expanded
They are fooling and enslaving you with these gadgets 👉 The Connections (2021) [short documentary] 💖
This is hype, to make a lens requires computational aperture synthesis which not talked about.
I can imagine the application for a future space telescope. It could be built in the shape of a half sphere, with the flat side designed to harness solar energy and protect the optics. The curved half sphere would serve as the optic element, maximizing its ability to capture and observe the entire region of space it faces. With this technique and technology, we could map the entire cosmos in greater detail than ever before.
If anyone else is wondering where to find more information related to the physics behind this, I would suggest looking into diffractive lenses.
This is a BIG subject -thanks !
Im glad it can see that black ice, its dangerous and could cause problems.
Something tells me that vehicle manufacturers could be considering that new lens technology for even more advanced safety systems, or something to alert a driver about black ice, and maybe turn the entire windshield into a HUD so the driver can see exactly where black ice or other hazards are.
The graphics are on another level
Most interesting topic I've seen this week... Crazy...
Please upload full documentry about this
I would love to work there. It only needs a few basic modifications to create a density scanner tuned to use wifi as the information carrier wave. Example, a mirror equivalent glass sheet in a home that uses the existing routers data broadcast to map a human body over a week or month. Finding changes in blockage, cancer growth, cyst, oxygen, etc.
The data compiled and a 3d model built.
Being able to avoid xray energy and mri magnetic rotations of molecules sometimes would save millions.
What excites me the most is the thought of using this tech in the next big space telescope.
We like the way you think. 👨🚀
Polarity modulation would add a whole generation worth of communication bandwidth. With this technique as is, you can split polarity into as many bands as you can fit regions on the chip.
Can these be used as logic gates to have a computer that works using the quantum properties of photons .. thus a room temp quantum computer
4:39 - there is no such thing as "transistor tube". "Transistor" is _not_ a generic term for "electronic switch". (BTW, those tubes were mostly triodes; before them there were electromechanical relays.) Precision, people!
Analysis of the atmospheres of exoplanets would be a great way to use this tech.
I mean you could say that our devices would be able to see the world in a whole new way. But our devices are an extension of ourselves. Obviously eventually we will figure out how to make contact lenses or some other sort of implant that would enable ourselves to experience it more directly. Just like going from a wheeled chair to prosthetic etc.
that was some cyberpunk sh*t right there, i'm in
That Zuckerberg joke was slick.
This will be more interesting when we can see a comparison of images taken with a meta lens and a standard cannon telephoto lens...
Star Trek Tricorders? YES PLEASE, thank you!
The day I can take my phone and scan a watermelon or some Halo oranges and determine if they're ripe / NICE AND SWEET or NOT is the day I'm waiting for!!
particle & wave duality operation, cool, hope to see in our lifetime.
Well, if there are already ready serial solutions, then a year or two and this 100 poods will be added to smartphones, and this is simply incredible.
I know it's mentioned to put it in layman's terms, but 1:29 is wrong about the speed of light changing. The apparent change in speed is a change in phase and group velocity, not actually the light slowing down.
Can this be used to make the light frequencies on a solar panel for example more efficiently move more electrons by causing better absorption of light?
I would like to see this in my lifetime! Please bring back the silicon valley!
Fantastic outside the box thinking!
Pretrained neural networks can be turned into light bending wafers. This would make their calculations millions of times faster than they are now.
Never mind what this could mean for your smartphone (although that’s very cool)…
Imagine what this could mean in the realm of lens exchange surgery. This would go far beyond “refractive lens exchange”, which I believe is currently our best technology for restoring clear vision. This could possibly, not only give you a perfect “correction” to vision…. but potentially could provide you with “an upgrade”.
Wow this is amazing!!!
Does Apple vision pro also use this technology?
I’d like to see this as implantable in the human eye. Imagine telephoto and macro vision without any external device. No one would need to wear glasses anymore.
Can it change the aperture?
I can't believe I missed this channel for so long. The algorithm failed me.
There are many useful applications for sensors adding polarization information, but not many I can think of that the average cell-phone user would have need for. It could be used for glare reduction in photography I suppose. The most practical use would be in potentially making cellphone camera lenses smaller and cheaper. I suspect camera miniaturization is more dependent on improvements in the sensors than the lenses. With enough light sensitivity, a pinhole camera would do.
One key feature is identity verification - polarization information makes it much harder to spoof a person's face or identity for facial ID applications.
@@NickFromHardReset true. So that alone would make it an important addition. And even though we might not need to include wavelengths outside the visible spectrum in most images, it could dramatically enhance accuracy of AI identification and interpretation of the physical world.
@@NickFromHardResetwhat are you talking about, why would there be durable polarized features in a face?
@@Cineenvenordquist I don’t think the camera is necessarily looking for durable polarized features- but the polarization data can provide a depth map, similar to other Face ID solutions, and it can also tell if the face it’s imaging is real or fake. A lot of their testing was with 3D printed versions of faces that could fool other cameras, but clearly read as artificial with polarization.
Are you kidding?
Having the power to map things in 3D or confirm that something is made out of what its purportedly made from and having it in then palm of your hand would be game changing.
Also, think about what it means in terms of health monitoring. The opportunities are endless here...all from 1 lens.
i thought this was one of those cheap attention grabbing videos but this seems quite probable and really intresting this could be world changing ... hope they release it quickly :P i want them.
Could this be used for VR Glasses? Sounds primising.
Can these meta lense also let us see sounds and let us see (almost) every scent?
I remember Texas Instruments developing the Digiital Micro Mirror chip that went into the iMax Theaters of the mid late 90s.
I was working in TI's Defense Systems Engineering Group(DESG) at the time. The development program group for DLP(DMD) sent us fully integrated projectors for field testing in our conference rooms and auditoriums. We were blown away at how crisp the full wall images were. Even the early video game images were outstanding. There were two major improvements DMD had over LCD, no visible address lines in large images and, angled edge lines of images were smooth, not "stair stepped" like LCD was.
BTW: TI won an Acadamy Award(OSCAR) for DLP image technology. Also, most high-end home theater video projectors use DLP's with Laser light sources. Especially the ultra-short throw models.
@@stvwds61 I hired into DSEG straight out of school. One of my school partners from a programmable chip sr project hired in to create applications for the DLP. Small world.
"More computational power than we know what to do with"
Don't worry software developers have you covered. We can apply our "clean code" practices and our SOLID principles to make any computer, no matter how powerful, feel slow and sluggish.
Hi Kami, you said you do affirmations all day, could you make a video about that, when do you say them during the day, do you record and play them on a Mp3 on repeat. What affirmations do you use, long or short? How do you word them? etc
Something similar to this concept used in a Kaleidescope so to say, to recieve signals from the brain or cerebellum to be used in a virtual avatar consiously for full dive VR
Any way to use this to detect clear-air turbulence? Low cost plane detection for General Aviation?
I'm excited specifically for the spectrographic analysis capabilities of these lenses and what applications those will find. Maybe a combinations of these lens types would allow us to accurately read information about items that we couldn't before. Imagine being able to view what a material is made of by simply placing your phone near it.
(Sept 2023) - Thanks for a carefully edited video to describe something OPTICALLY EPIC & AWESOME!! It's been said, "The Future is OPTICS." I agree after seeing this video.
Idk what normal people would do with this but what immediately comes to mind are inspection drones in agriculture and industry
It blows my mind that this came out 3 months ago, and I'm just now getting to see it... (Thanks youtube?)
I like the unknown part of the impact this technology will have.
Smartphone is a platform for individuals, it is amazing how it will continue to develop with new technologies.
Sometimes the future seems so beautiful it makes me want to cry.
Could you market at present two lens solutions, one all of the optical components required to make an 12/18/24 inch, refractor telescope and two a replacement eye lens for the blind which would help with restoring eyesight?
this could revolutionize everything including the cameras and such on infrared cameras on the military tracking and such
Can you make a 100m space telescope lens out of these? Or, replace the lenses used in consumer telescopes and electronics?
I think you could just "simulate" anamorphic and fish eye effect with these flat lenses.
In the 70's I read a far fetched event that I wanted to believe so much. Knowledge of the lamp in a flying saucer that could control its focus from a very wide angle to be able to light, let's say, an underwater cave, to a narrow beam that could light a small area miles away, to the sharpest laser-like beam. I imagine this lens is headed that way.
Awesome!
On a different topic...
Is it that "each" view of a quantum entanglement pair severs the connection, therefore can only send a single binary, meaning 8 paired particles equals 8 bytes... and once all the particles are viewed, then there is no longer a way to quantum communicate?
.
Next question, if yes... considering there is actually quantum teleportation, why not always teleport an entangled particle through each "signaling" to keep the quantum communication going?
.
If able to teleport 2 particles through a single quantum entangled particle... can that then be made to provide constant electrical power from a power source from any distance... and can that also be used for traversing across space fueled from Earth* (*etc)?
Amazing 😍😍
Metamaterial optical lenses aren't new. Victor Veselago's 1961 paper "The Electrodynamics of Substances with Simultaneously Negative Values of ε and μ" showed the possibility of metamaterial lensing by introducing the possibility of a negative index of refraction and matter affecting the reaction of light. See the Wikipedia entry: Superlens. The first microscope Superlens using a metamaterial increased the resolving power of a light microscope from 200 nanometers to 100 mn in 1981.
Putting together the mathematics, computer power, and fabrication facilities to design and build Metalenz's metamaterial lenses will change many facets of optics. The prediction of size and mass creates a whole new kind of camera.
I'm not sure why "Actor Portrayal" on the video of Galileo tickled me so much. 😂
I know that it is already a work of art, but it would be awesome to see meta materials be used to make gallery art. 0:10
Yeahhh this is actually awesome
Amazing!
this would be perfect for headsets with the metaverse. the branding is even there already.
Put these "tricorders" on our glasses directly !
New sub 🔥🔥
Exciting stuff
There are a lot of posts that I have probably not read but has there been any mention of using the lens on human eyes and possibilities for eyesight issues.
Portable, multi spectral imaging has been a dream of mine too, specifically seeing in complete dark, itentifying the material a thing is made from, see through vegetation or walls etc ... quite magical; but which may also restrict its uses to law enforcers and military (?). Unless its released under licence widely before the law catches up.
Pry the IR filter off a webcam and replace it with a vis cut filter and hey presto, night vision. strip the foil off a CDR and take a picture of a candle or something through that. Boom spectroscopy on the cheap.
The technology may become cheap so it kight readily be availbke to the average consumer
