"This lens looks ordinary, it seems to be a hexagonal honeycomb grille on the lens. But in fact these honeycomb grilles are not the surface, but inside the lens.
If it is just a layer of hexagonal honeycomb grille, it will not change the light transmission of the lens or each hexagonal honeycomb.
But our lens can change the different light transmission of each hexagonal honeycomb grille. "
As Wu Hao turned the lens, a beam of light hit the lens, and after passing through the lens, it hit a piece of white paper. I saw many bright spots of different sizes appearing on this white paper.
"Because each hexagonal grid lens has a different focal length, these aggregated light spots naturally have different sizes.
This is very important, everyone should remember, especially consumers in the future, should pay attention to observation, do not be deceived by cottage products. "
Wu Hao smiled, then went on to say: "It would be very difficult for such a lens to be manufactured in the normal way. This means that we need to process different bumps on the surface of a large lens. "
As Wu Hao spoke, the screen also showed the style of the lens Wu Hao said.
"The lenses produced in this way are very difficult to process, and the manufacturing cost is very high, and the yield is very low.
So in the end, after our 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 crops.
Through the laser printing or laser engraving technology, the outline of the hexagonal honeycomb lens is engraved or printed in the high lens sheet made of special materials.
And this is just the first step. Although the outline of the lens lens has appeared, it cannot be affected by the structure of other redundant lenses and cannot produce optical refraction.
Therefore, at this time, we need special treatment for the lens material of other parts than the hexagonal honeycomb lens lens, so that it loses the glass refraction phenomenon.
In other words, when the optics pass through this glass, there will be no refraction. In this way, the engraved lens lens inside the lens works. "
Genius idea!
The audience who were watching the live broadcast of the new technology promotion meeting could not help admiring, and countless industry insiders could not help laughing.
This technology sounds easy, and it seems the principle is very simple, but why no one has done it before.
Craftsmanship, what Wu Hao deliberately ignored in the lecture.
I don’t know what the lens material is. I don't know what laser printing and engraving technology is used. It is not known how to eliminate the light transmission and refraction phenomenon of excess lenses.
This is the biggest difficulty of this technology.
After taking a sip of water, Wu Hao went on to say: "Now that the hexagonal honeycomb lens has been successfully manufactured, can the lens be produced?"
Wu Hao shook his head and said, "There are still many problems.
The first problem is how to reflect the focus of these large and small hexagonal honeycomb lens lenses onto a photosensitive component.
These hexagonal honeycomb lens lenses have different sizes and different thicknesses, so the length of the focal point will naturally be different. How to focus these focal points on a photosensitive element is a difficult problem. "
After throwing this question, Wu Hao paused for a while, then replied: "Mirror, lens!"
"We use the principle of mirror reflection and lens refraction to work together. In the end, the focal points of these hexagonal honeycomb lens lenses are all focused on the photosensitive components.
And by adjusting the angle of these mirrors and lenses, we can change the focal length of these lenses to adjust the zoom. "
With that said, this hexagonal honeycomb compound lens appeared in front of Wu Hao. The entire lens floats in the air and slowly rotates.
Snapped!
Wu Hao snapped his fingers, and this hexagonal honeycomb compound lens actually broke up in the air.
By stretching the lens, the audience can more intuitively see the complex structure inside this hexagonal honeycomb compound lens.
With that, Wu Hao tapped a little with his finger, and a beam of light came directly, the light passed through various lenses, and then gathered on the surface of the photosensitive element.
"Using this manufacturing process, we can process multilayer lenses on one lens. In theory, this number can be infinite, depending on the thickness of the lens material.
We can even sculpt numerous lenses and mirrors in one lens material or one lens material.
The light is continuously refracted and reflected by these lenses and mirrors, and finally achieves the corresponding optical effect. "
So what's the use of this compound lens technology made in this way?
After throwing 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 large, even greater than you all think.
With this compound lens technology, not only can we make hexagonal honeycomb compound lenses, but also use it to create light.
That's right, create light!
What did you think of? "
"Laser, this is the man-made light source with the most energy that we humans make. And our compound lens is an ideal laser light source lens.
We have done tests. Under the same power source, the laser power of our compound lens technology is more than 50% higher than that of lasers using conventional lenses, and we think there is still much room for improvement in this regard. .
I believe that everyone will know what this means, and what changes it will bring to our industrial production and processing and other applications. "
After throwing such an amazing result, Wu Hao did not pause, but continued to improve his tone.
And what I want to say is that this is not all. Using this compound lens technology ~ EbookFREE.me ~ we can use it to make an extreme ultraviolet light source.
In theory, with this technology, we can directly compress the extreme ultraviolet light source to the level of the current international advanced extreme ultraviolet light source, even better!
what!
This time, many people stood up directly.
How can this be?
The audience exclaimed one after another, knowing that the extreme ultraviolet light source is the core technology of the lithography machine. After conquering this technology, the lithography machine is not a problem at all.
Now, Wu Hao and they actually claim that they can manufacture the world's cutting-edge extreme ultraviolet light source. How could this be possible?
Don't believe it, don't believe it. This is the first reaction of countless people after hearing this news.
