"You should know," said Director Zhao with some emotion, "Good camera lenses are imported, which is our shortcomings."

Chatting with such a big intellectual is really a bit heart-warming. As I was talking about it carefully, why did the mirror glass be pulled onto the camera lens again?

A great intellectual always likes to speak in a circumference. Zheng Guolin dared not say much, for fear that he would show his timidity in front of others.

"I don't know much about photography, but I heard about it." He replied to Director Zhao.

"A good camera lens has very high requirements for light transmittance, which requires that the glass for making the lens must have a high light transmittance itself." Director Zhao explained, "We already know how to obtain glass with relatively high light transmittance. Adding a certain proportion of manganese to the glass can meet this requirement."

Zheng Guolin didn't understand this thing even more, so he could only nod and continue to listen to this great intellectual.

"But it is not enough to obtain only glass with a light transmittance that meets the requirements." Director Zhao continued, "The glass surface must also be polished very smoothly and smoothly to reduce the scattering or diffusion caused by the unevenness of the glass surface, so that most of the light will pass through the glass and conduct it to the other side of the glass to ensure this high light transmittance. This is a problem that we cannot solve."

Speaking of this, Director Zhao pointed to the dark blue glass block brought by Zheng Guolin on his desk and said, "This piece of glass, as I just said, is the kind of high-transmittance glass."

I see.

Zheng Guolin asked: "What do you mean is that the reflector on the lithography machine and the advanced lens of the camera are the same?"

Director Zhao nodded seriously and said, "Yes. But the transmittance requirements of the reflector are higher than those of the camera."

Speaking of this, he said to Zheng Guolin: "You know, the European Space Agency's space telescope Hesher has a lens diameter of 3.5 meters, far exceeding the United States' Hubble. It only took nearly two years to polish this lens. And the lens polishing technology is currently the most advanced in Europe and Japan, and Europe is far ahead, so they can make such an advanced deep space telescope."

It seems that Evelyn had mentioned the lens polishing technique to her. However, the purpose of Evelyn's words to him was mainly to collaborate with Chen Haiping to defraud him. She said it was taught by Chen Haiping, and she didn't understand it herself.

"What do you mean, do you mean, we can't polish the lenses?" he asked Director Zhao.

Director Zhao admitted: "Yes, we are not at all in this regard, and we are not at all in the beginning.

Regarding this technology, I will say that our Institute of Optical and Mechanical Engineering has also invested a lot of manpower and financial resources, and has been researched for more than ten years, but the results have been minimal."

Speaking of this, he paused, then looked at Zheng Guolin and said, "The reflective lens you brought was made by the most advanced lens company in Germany. It was them who created the lenses of Hesher and Planck, the two space telescopes for the European Space Agency. This reflective lens gave us another idea."

Director Zhao said a lot in a mess, but now it seems that he has just begun to get to the point.

Zheng Guolin didn't dare to interrupt him, but just listened to him silently.

Director Zhao said: "According to the inside of Asml, the reflector lens of this lithography machine has higher light transmittance requirements than the requirements of aerospace telescopes. Its accuracy is equivalent to leveling the entire German land to a plain with an error of less than one centimeter. Imagine that this difficulty is probably not something that humans can do.

We are an ancient civilization country with a history of civilization of 5,000 years, lens grinding technology, and at least three thousand years of history. Is three thousand years of technical accumulation not as good as those of others' decades of experience? This is something that none of us optical experts can understand.

Their lens polishing technology is not as mysterious as the legendary one.

Of course, modern lens grinding technology still has completely different methods and methods from our ancient metal mirror grinding. The microscopic technology and detection technology are all modern and would not have been available in ancient times.

However, some of the other polishing techniques have been accumulated from ancient times to the present, and have only been microscopicized."

Speaking of this, Director Zhao thought about it before continuing: "It may not be easy for you to understand this. I will give you an example.

In the 1980s, it was just changed. The polishing technology of our hero pens is something foreign countries don’t understand or do not have. Therefore, their Parker pens are far behind our thousand-year polishing heritage in this regard.

They came to us and contacted us in the name of investment cooperation. At that time, we were much stupider than we are now. When we heard that the other party wanted to invest money, we immediately forgot that the other party was the enemy, at least in terms of economic and trade competition, we were our enemy.

So we asked them to visit our polishing workshop.

At that time, we didn't even recognize the camera, so we asked everyone to record the entire polishing process of the pen.

Then, they went back, carefully studied the video, and understood our polishing process little by little. Then, of course, they did not cooperate with us. Parker Pen, from then on, has had the polishing technology of hero pens, occupying the world market of hero pens."

Speaking of this, Director Zhao was a little excited.

"The loss of this technology is probably priceless, because we have lost the entire world market!"

He sighed a long time and continued.

"There are so many similar leaks. For example, our ceramics, a ceramic manufacturer in one of the four major contemporary kilns, and a pair of two and a half meters high dragon relief vases given to the United Nations by our country. Their reinforced porcelain, Huashi porcelain as thin as a cicada's wing, is as crystalline as jade, better than white snow, can almost reach transparency, and bone porcelain is as light as nothing in hand.

These porcelain making technologies were not available in Europe. They also came to discuss cooperation when we were so stupid that we were so stupid that we were retarded. They invested only 100,000 yuan to build a section of the road at the entrance for the ceramic factory, and easily gained trust and stole these technologies that they had developed for one hundred years but couldn't understand for a thousand years.

Since then, their ceramic technology has made rapid progress and occupied the world market. Our factory, which once earned over 100 million meters of foreign exchange for the country every year, eventually went bankrupt!

This is the concept of Westerners! In their hearts, they always believe that only they are the best in the world and the master. And we Asians and Africans are inferior people, and can only be their slaves and serve them."
