"This lens looks ordinary, as if it has some hexagonal honeycomb grilles on the lens. But in fact, these honeycomb grilles are not on the surface, but inside the lens.
If there is just a layer of hexagonal honeycomb grille, it will not change the light transmittance of the lens or each hexagonal honeycomb.
As for our lens, it can change the different light transmittance of each hexagonal honeycomb grille. "
As he spoke, Wu Hao turned the camera, and a beam of light shot towards the camera, passed through the camera, and hit a piece of white paper. I saw many super bright light spots of different sizes appearing on this white paper.
“Because the focal length of each hexagonal grid lens is different, the sizes of these concentrated light spots are naturally different.
This is very important. Everyone, especially future consumers, should pay attention and be careful not to be deceived by counterfeit products. "
Wu Hao smiled and then continued: "Such a lens would be very difficult to manufacture according to normal methods. This means that we need to process different concave and convex points on the surface of a large lens. "
While Wu Hao was speaking, the screen also displayed the style of the lenses Wu Hao was talking about.
“The lenses produced in this way are very difficult to process, the manufacturing cost is very high, and the yield rate is very low.
So in the end, after repeated research, we changed the manufacturing idea of this hexagonal honeycomb lens. We decided to abandon this traditional lens processing method and instead use a new set of technologies developed by our company.
Through laser printing or laser engraving technology, the outline of a hexagonal honeycomb lens is engraved or printed in a high-lens lens made of special materials.
And this is just the first step. Although the outline of the lens has appeared, it is affected by other redundant lens structures and cannot produce optical refraction.
So at this time, we need to perform special processing on the lens material of other parts of the hexagonal honeycomb lens to make it lose the glass refraction phenomenon.
In other words, when optics pass through this glass, there will be no refraction. In this way, the lens lens carved out inside the lens comes into play. "
Genius idea!
The audience who were watching the live broadcast of the new technology promotion conference couldn't help but admire it, and countless people in the industry couldn't help but smile bitterly.
This technology sounds easy, and the principle seems to be very simple, but why has no one done it before?
Craftsmanship is something Wu Hao deliberately ignored in his presentation.
I don’t know what lens material it is. I don’t know what laser printing and engraving technology is used. I don’t know how to eliminate the light transmission and refraction of the excess lens.
This is the biggest difficulty with this technology.
After taking a sip of water, Wu Hao continued: "Now that this hexagonal honeycomb lens has been successfully manufactured, can we produce lenses?"
Wu Hao shook his head and said: "There are still many problems.
The first problem faced is how to reflect the focus of these large and small hexagonal honeycomb lenses onto a photosensitive component.
These hexagonal honeycomb lenses have different sizes and thicknesses, so the length of the focus is naturally different. How to focus all these focuses on a photosensitive element is a thorny problem. "
After posing this question, Wu Hao paused for a while and then replied: "Mirror, lens!"
"We use the principles of mirror reflection and lens refraction to finally align the focus of these hexagonal honeycomb lenses on the photosensitive components.
And by adjusting the angles of these mirrors and lenses, we can change the focal length of these lenses, thereby making zoom adjustments. "
As he spoke, this hexagonal honeycomb compound eye lens appeared in front of Wu Hao. The entire lens is suspended in the air and slowly rotates.
Snapped!
Wu Hao snapped his fingers, and this hexagonal honeycomb compound eye lens actually disintegrated in the air.
By stretching the lens, the audience can more intuitively see the complex structure inside this hexagonal honeycomb compound eye lens.
As he spoke, Wu Hao tapped his finger a little, and a beam of light came directly over. The light passed through various lenses and then gathered on the surface of the photosensitive element.
“Using this manufacturing process, we can process multiple layers of lenses on one lens. Theoretically, this number can be infinite, depending on the thickness of the lens material.
We can even carve numerous lenses and mirrors into one lens material or piece of lens material.
Light is constantly refracted and reflected through these lenses and mirrors, ultimately achieving the corresponding optical effects. "
So what is the use of this composite lens technology manufactured in this way?
After raising this question, Wu Hao did not rush to answer, but gave the audience watching the live broadcast some time to think.
After waiting for about ten seconds, Wu Hao slowly replied with a positive tone: "The effect is very powerful, even greater than you all imagined.
Using this compound lens technology, we can not only make our hexagonal honeycomb compound eye lens, but also use it to create light.
That’s right, create light!
What did everyone think of? "
"Laser is the most powerful artificial light source produced by humans. Our composite lens is an ideal laser light source lens.
We have done tests and found that under the same power of light source, the irradiation power of lasers using our compound lens technology is more than 50% higher than that of lasers using conventional lenses, and we believe there is still a lot of room for improvement in this area. .
I believe that everyone must know what this kind of improvement means, and what changes it will bring to our industrial production, processing, and applications in other fields. "
After presenting such an amazing result, Wu Hao did not pause, but continued to speak in a higher tone.
And what I want to say is, this is not all, using this composite lens technology, we can use it to create extreme ultraviolet light sources.
Theoretically, using this technology, we can directly compress the extreme ultraviolet light source to the level of the current international cutting-edge extreme ultraviolet light sources, or even better!
What!
At this time, many people stood up directly.
How can this be?
The audience exclaimed in surprise, knowing that extreme ultraviolet light source is the core technology of lithography machines. Once this technology is conquered, the photolithography machine will not be a problem at all.
Now, Wu Hao and the others actually claim that they can create an internationally advanced extreme ultraviolet light source. How is this possible? I'm afraid they are just bragging.
Don’t believe it, don’t believe it. This was the first reaction of countless people after hearing the news.
