"This lens looks ordinary, as if there are some hexagonal honeycomb grids on the lens. But in fact, these honeycomb grids are not on the surface, but inside the lens.

If there is only one layer of hexagonal honeycomb grid, it will not change the light transmission of the lens or each hexagonal honeycomb.

But our lens can change the light transmittance of each hexagonal honeycomb grid. "

As Wu Hao turned the camera, a beam of light shot towards the camera, and after passing through the camera, it hit a piece of white paper. I saw many super bright light spots of different sizes appearing on the white paper.

"Because the focal length of each hexagonal grid lens is different, the size of these concentrated light spots is naturally different.

This is very important, everyone should remember, especially future consumers, pay attention to observe, and don't be fooled by counterfeit products. "

Wu Hao smiled, and then continued: "It will be very difficult to manufacture such a lens according to the normal method. Because it 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 was also displaying the style of the lens in Wu Hao's speech.

"The lenses produced in this way are very difficult to process, and the manufacturing cost is very high, and the yield rate is still 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 method of lens processing and instead use a new set of technologies developed by our crops.

Through 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 only the first step. Although the outline of the lens has already appeared, it cannot produce optical refraction due to the influence of other redundant lens structures.

So at this time, we need to perform special treatment on the other parts of the lens material outside the hexagonal honeycomb lens lens to make it lose the glass refraction phenomenon.

That is to say, when the optics passes through this glass, there will be no refraction phenomenon. In this way, the lens lens carved out of the inside of the lens works. "

Genius idea!

The audience who were watching the live broadcast of the new technology promotion meeting couldn't help admiring,

And countless people in the industry couldn't help laughing bitterly.

This technology sounds easy, and it seems that the principle is very simple, but why has no one done it before.

Craftsmanship, something that Wu Hao deliberately ignored in his lectures.

What lens material, I don't know. I don't know what laser printing and engraving technology is used. How to eliminate the light transmission and refraction phenomenon of the redundant part of the lens is not known.

This is the biggest difficulty of this technology.

After taking a sip of water, Wu Hao continued: "Now that this hexagonal honeycomb lens has been manufactured successfully, 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 focal points of these large and small hexagonal honeycomb lenses onto a photosensitive component.

The size and thickness of these hexagonal honeycomb lenses are different, so the length of the focal point is naturally different. How to concentrate these focal points on a photosensitive element is a tricky problem. "

After asking this question, Wu Hao paused for a while, and then replied: "Mirror, lens!"

"We used the principles of mirror reflection and lens refraction to align the focus of these hexagonal honeycomb lens lenses on the photosensitive components.

And by adjusting the angles of these mirrors and lenses, we can change the focal length of these lenses to perform zoom adjustment. "

With that said, this hexagonal honeycomb compound 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 lens actually disintegrated in the air.

By stretching the lens, the audience can more intuitively see the complex structure inside the hexagonal honeycomb fly eye lens.

As he spoke, 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 multiple layers of lenses on one lens. In theory, this number can be infinite, depending on the thickness of the lens material.

We can even engrave many lenses and mirrors in one piece of lens material or in a piece of lens material.

The light is continuously refracted and reflected through these lenses and mirrors, and finally achieves the corresponding optical effect. "

So what is the use of this composite lens technology manufactured in this way?

After asking this question, Wu Hao did not answer in a hurry, 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 what you all imagined.

Using this compound lens technology, not only can we make our hexagonal honeycomb fly eye lens, but we can also use it to create light.

That's right, make light!

What do you think of? "

"Laser, this is the artificial light source with the highest energy produced by human beings. And our compound lens is an ideal lens for laser light source.

We have done tests, and under the same power source, the irradiation power of lasers using our compound lens technology is increased by more than 50% compared with lasers using conventional lenses, and we think there is still a lot of room for improvement in this regard .

I believe that everyone must know what such an improvement means, and what changes it will bring to our industrial production and processing and applications in other fields. "

After throwing out such an astonishing result, Wu Hao did not pause, but continued to speak with a raised tone.

And what I'm saying is, that's not all, with this compound lens technology, we can use it to create extreme ultraviolet light sources.

Theoretically, with this technology, we can directly compress the extreme ultraviolet light source to the level of the current international cutting-edge extreme ultraviolet light source, or even better!

what!

All of a sudden, many people stood up directly.

how can that be?

The audience exclaimed one after another. You must know that the extreme ultraviolet light source is the core technology of the lithography machine. Once this technology is overcome, then the lithography machine will not be a problem at all.

Now, Wu Hao and the others actually claim that they can manufacture an extreme ultraviolet light source of international cutting-edge level. How is this possible? I'm afraid it's just bragging.

Do not believe, do not believe. This is the first reaction of countless people after hearing the news.
