Kunshan, Jiangsu, a wholly-owned subsidiary of Xingchen Technology, Xingchen Optics.

Guo Shouyu followed Luo Jia here, met the person in charge Zhang Yuechuan and Lu Chengfeng, and the two sides exchanged pleasantries, and then went to the fourth workshop under the leadership of Zhang Yuechuan.

"This is a trouble, since you have a space telescope program, why didn't you say it earlier?"

"I wonder how the mirror you designed compares to the latest Webb telescope in North America?"

Walking on the road, Guo Shouyu asked a lot of questions, but Zhang Yuechuan and Luo Jia were embarrassed and did not answer immediately.

Luo Jia frowned and said, "Well... Our space telescope is still quite special, the reason why we did not notify everyone in advance, also has its own reasons, in short, it is more difficult to explain, you will know after a while. ”

"Hard to put into words?" Guo Shouyu was suspicious, "Then I want to see, can your space telescope still go against the sky?" For so many years, telescopes all over the world have had almost the same design, because the optical principle is there. ”

Luo Jia and Zhang Yuechuan glanced at each other, didn't say anything, and continued to walk forward.

The fourth workshop is independent of the factory area, connected by a long and narrow corridor, and the access control is also very strict, everyone has to pass the iris detection, and then pass through a huge metal reinforced door to finally enter the inside of the workshop.

"Robots!"

After entering the workshop, Guo Shouyu's eyes suddenly lit up and he exclaimed.

This is a futuristic factory with a very advanced concept, and the main productivity comes from human engineers, hardcover robotic arms, and general-purpose work robots led by Star Feathers.

Among them, humans are more responsible for supervision and management, and the ultra-fine work of processing optical lenses is completed by robots and robotic arms to ensure the accuracy of the final assembly.

"These are your lenses!?"

Guo Shouyu suddenly stopped, looked at the huge optical lens in the clean room, and showed an incredible look, as if he had seen some kind of frightening monster.

"Yes, what you see is the main lens that we make for space telescopes." Zhang Yuechuan replied a little blandly.

Guo Shouyu was completely stunned, because this lens had exceeded his imagination, and roughly estimated that the diameter was at least twenty-five meters or more, which was equivalent to the height of an eight-story building.

You must know that the famous Hubble Space Telescope has an aperture of only 2.4 meters, and the Super Space Telescope Webb, which costs tens of billions, has an aperture of 6.5 meters, but the space telescope designed by Xingchen Technology has a diameter of more than an astonishing 25 meters.

"You... You didn't even use storyboarding!? Guo Shouyu was stunned for a full minute before he asked in surprise.

Luo Jia pursed his lips, "Indeed, the Webb Space Telescope in North America uses eighteen hexagonal lenses, with a single piece in diameter of 1.3 meters and a weight of 40 kilograms. ”

"However, the question is, does the hexagonal spliced lens really mean that the technology is advanced?"

"I don't think so, the reason why North America adopts the combined design is not from an optical point of view, but more due to the stability of the mechanical mechanism, the flexibility of the motor control system, the limited volume inside the rocket carrier, and the total cost control and other related reasons."

"In other words, North America wants to use a one-piece round mirror like us, but unfortunately they can't build it, and the strength of the mechanical structure can't support this kind of super large lens, a telescope with a total weight of several hundred tons, and there is no such high-power launch vehicle in the West."

Although Xingchen Optics is a rising star in the industry, it has long been out of the blue, and the ultraviolet laser hybrid lithography machine, the complex and unparalleled lens system, Xingchen Optics can be successfully developed, which shows the high level of this team.

In terms of auxiliary systems, the main mechanical structure of the Xingchen Space Telescope uses more advanced graphene materials, more powerful ultrasonic motors, and the transportation does not rely on rocket launches, but on space elevators located on Weigu Island, which are not available in the West.

Its own conditions are different, and the gameplay is also different, so Xingchen Technology chose a simple and crude route and built a giant weighing several hundred tons.

"Not necessarily, right?" Guo Shouyu thought for a moment and said: "After Weber is divided into small mirrors, each small mirror actually has a motor controlled separately, so that if there are any optical aberrations that need to be adjusted, they can be controlled more flexibly. ”

"I think back then, after the Hubble telescope was sent to the sky, some optical aberrations were found, and North America went crazy to find the reason, it turned out that in the Hubble primary mirror system, there was an error in a calibration mirror, which eventually led to the primary mirror being polished into a wrong shape very accurately, and they spent a lot of money and a lot of effort to correct the error, and the storyboard system exists to correct the error."

Hearing this, Luo Jia smiled and said lightly: "Only if there is an error, the storyboard system needs to be corrected, and the accuracy of our lens is 0.1 nanometer, there is no error, so there is no need for storyboarding." ”

"How much!?"

"What was the error of this lens!?"

Guo Shouyu grabbed his hair hard with his right hand, and almost jumped up in place with excitement, and his voice was obviously an octave higher.

"Tenths of a nanometer." Luo Jia replied calmly.

Guo Shouyu gasped, he was shocked at first, and then showed an ecstatic expression.

It is difficult for people who have not engaged in astronomical observation to understand what the accuracy of 0.1 nanometer means, which costs more than 10 billion US dollars and is known as the most powerful space telescope of mankind in the 21st century, the North American Webb, what is its lens error?

Ten nanometers.

Xingchen Technology has achieved 0.1 nanometer, and the error is only one percent of Webb's.

What's even more incredible is that the diameter of the Webb lens is 1.3 meters, while the diameter of the lens of Xingchen Technology is 25.537 meters, which is 19.63 times that of the Webb!

On such a huge lens, to achieve an almost zero error, I really don't know how Xingchen Technology did it, such a feat will definitely rewrite the history of the field of astronomical observation on the earth.

"Instead of using traditional grinding, we used robots and laser grinding." Luo Jia said lightly: "You may have forgotten that when we were researching the lithography machine, we took out high-energy physics and set up a separate research institute, with Xu Guangling as the president and Wen Chengling as the chief consultant." ”

"Wen Chengling's main focus is still in the Department of Life Sciences, but it also plays a very key role in the work of the Institute of High Energy Physics, anyway, we have invested heavily in the laser field, we don't have laser rapid-fire guns, but laser precision machinery, we still developed a few."

Guo Shouyu doesn't know what to say, this is Xingchen Technology, a super bull aggregate, Xu Guangling did not come to Xingchen Technology, he was the rising star of the Institute of High Energy of the Chinese Academy of Sciences, and his strength should not be underestimated, and Wen Chengling is even more legendary, from a top laser expert, to the study of life sciences, the discipline span is large, which can be called unprecedented, not to mention, he also succeeded, and really became a wonderful scientist across high-energy physics and life sciences.

"Let's not stay here, right?" Zhang Yuechuan looked at his watch and said, "Everyone is waiting, and the real thing to show you is still behind." ”

Ay~

Guo Shouyu suddenly had a sense of grandma Liu's entry into the Grand View Garden, thinking that he was also the director of the National Astronomical Observatory, an expert in the field of astronomical observation who had seen the world, and after coming to Xingchen Technology, he felt that his eyes were not enough, and he felt fresh when he saw everything.

As the saying goes, people are more popular than people, and that's probably the truth.

Walking through the busy production workshop, the group entered the test assembly area, where various parts will be assembled and produced into final products.

"Oh my God, these are all space telescopes!?" Guo Shouyu stopped and asked, he looked at the behemoths in front of him, and felt that his legs were a little weak, and he couldn't take a step.

"Yes." Luo Jia said in a deep voice: "In addition to optical mirrors, we have also prepared X-ray mirrors, infrared mirrors, ultraviolet mirrors, and radio microscopes. ”

"Let's put it this way, the full name of our project is called the Eye of the Stars, and it is not composed of a single astronomical telescope, but a complete array of astronomical observations."

Eyes of the Stars!

A complete array of astronomical observations!

Not a single space telescope, but an array of many telescopes!

Realizing the meaning of Luo Jia's words, Guo Shouyu felt that the whole person was about to explode, this is probably Luo Jia's favorite corner overtaking, when the West was desperately building a space telescope, he created a composite super observation array!

"Did you ask Enron to rearrange the plan, did you prepare to put that eye of the stars on space station zero?" Guo Shouyu asked.

Luo Jia smiled and shook her head, "Of course, there will be telescopes installed on Space Station Zero, but the Eye of the Stars will not be placed there. ”

There happened to be a star map of the solar system beside him, Luo Jia observed, and then pointed lightly and said: "The eye of the stars will be placed here, the five special solutions to the restrictive three-body problem, the Lagrange point!" ”
