In a blink of an eye, Wang Bin and his team at Tiangong Technology have passed the project approval application, and one month has passed. In this month, Wang Bin and his team at Tiangong Technology have designed and completed the first drone, and it has entered the official stage. under construction.

If there is no accident, a week later, the drone produced by Tiangong Technology will officially test flight. However, since Tiangong Technology does not have its own airstrip yet, even if the drone is manufactured by then To come out, you must also go to a professional flight test center to complete.

However, when Wang Bin and Tiangong Technology were making full efforts to manufacture drones and contacted the flight test base to prepare for the test flight, the optical glass produced by Tianyuan Optics, a subsidiary of Tiangong Technology, had been immersed for such a long time. The effects are finally starting to show.

During this period of time, Tianyuan Optics has quietly made a big move, that is, Tianyuan Optics, using their own glass mirrors during this period of time, successfully produced a glass mirror in such a short period of time. A common optical astronomical telescope lens with a diameter of 78.6 meters.

Of course, it is impossible for the main lens of such a large astronomical telescope to have only one piece of glass. Let alone whether Tianyuan Optics can manufacture such a large optical glass, it is definitely a big problem in terms of transportation, so this Like other relational telescopes, the telescope is also made up of multiple hexagonal mirrors.

And after Tianyuan Optics announced the manufacture of the main lens of an ordinary astronomical telescope with a diameter of 78.6 meters, it immediately announced that it would work with the city officials to install this telescope on Cangshan, the highest mountain in the city. .

As soon as Tianyuan Optics announced this news, it immediately caused a very strong sensation in the world. You must know that this is a sensation all over the world!

After all, the difficulty of manufacturing super-large ordinary telescopes is well known. Not to mention other things, just for now, the largest ordinary astronomical telescope in the world, the Canadian column of large telescopes, has a diameter of only more than ten meters, but in order to manufacture Some countries in the Western Continent invested nearly 200 million euros in this telescope!

Even the largest astronomical telescope currently under construction, that is, the astronomical telescope that will be completed in 2022.

The diameter of its main lens is only 39.3 meters, but the diameter of the lens of this astronomical telescope produced by Tianyuan Optics has reached 78.6 meters, which is twice the size of the telescope under construction in the Western Continent.

You must know that before, the largest ordinary optical astronomical telescope in China had a maximum aperture of less than three meters.

And due to various reasons, even if Huaxia wants to build such a super-large ordinary optical astronomical telescope,

It is very difficult, and the biggest difficulty is that it is stuck on the main lens of the astronomical telescope. Even if you want to buy it from abroad, it is very difficult, and it can even be said to be basically impossible.

However, now, Tianyuan Optics, let alone in the world, even in China, is just an inconspicuous optical glass manufacturer, and its scale is not large.

However, such a small optical glass manufacturer quietly manufactured the main lens of the world's largest ordinary astronomical telescope.

Perhaps in the eyes of ordinary people, this kind of technology is nothing. After all, the technology of human civilization is so advanced now that it is not just to make ordinary astronomical telescopes, which can be done easily.

But in fact, this is not the case. Even ordinary optical astronomical telescopes, especially the main lenses of large-caliber ordinary optical telescopes, are definitely beyond everyone's imagination. Otherwise, the diameter of China's largest ordinary optical telescope would not be large. It will be less than three meters.

Of course, this is not the most important thing. The most important thing is that the announcement of Tianyuan Optics is not that they plan to manufacture such a huge astronomical telescope main mirror, but that they have already manufactured such a large main mirror, which is appalling.

You must know that foreign optical glass manufacturers want to manufacture the main mirror of a very large astronomical telescope. What about Tianyuan Optics!

Although everyone does not know how long it took Tianyuan Optics to manufacture the main mirror of this telescope.

However, anyone who has a certain understanding of Tianyuan Optics will definitely know that it will definitely not take more than a year for Tianyuan Optics to manufacture the main lens of this telescope.

So this news, like a bolt from the clear sky, spread throughout the astronomical and even scientific circles, and caused a huge shock.

"Have you heard that our country is planning to build the world's largest astronomical telescope?"

"Isn't the world's largest radio astronomy telescope in China? Is it going to be rebuilt again? Or is it going to be built bigger?"

"No, I think you are wrong. The astronomical telescope to be built this time is not a radio telescope, but an ordinary optical telescope. It is said that the main lens of the telescope we are going to build this time is 78.6 meters high, and its The master mirror has already been manufactured.

You must know that the main lens of the world's largest ordinary optical telescope has a maximum diameter of only more than ten meters. Even if it is under construction, its maximum diameter is only 39.3 meters.

That is to say, the ordinary optical telescope that our country is going to manufacture, even if it is directly compared with the largest optical telescope under construction in foreign countries, its diameter is twice their diameter. "

"Which company made it? It's so awesome. I remember that technology like this seems to be blocked from us by foreign countries!"

"Yes! It is said that the company that produced such a large-diameter main lens this time seems to be called Tianyuan Optics, and it is a purely private enterprise."

"Yes! In fact, this is not the most shocking news. The most shocking news is that according to the official announcement of the company and the location, they actually want to complete the construction and installation of this telescope and put it into use within one year.

In other words, if there are no accidents and everything goes well, then the telescope will be put into operation earlier than the world's largest optical astronomical telescope, which is currently under construction in the Western Continent. "

Of course there are those who praise it, and those who depreciate it. After all, this is the Internet age, and there are all kinds of people.

Some people think that Tianyuan Optics is simply looking for trouble, doing such a thankless thing.

Some people also think that Tianyuan Optics and the local government are simply wasting taxpayers' money to build the world's largest astronomical telescope. After all, the world's largest astronomical telescope is currently under construction, that is, the main mirror with a diameter of 39.3 meters. The investment is as high as more than one billion euros.

So what about this astronomical telescope with a diameter of up to 78.6 meters? It is conceivable that the investment will be at least three times higher than that under construction abroad.

Of course, what they don't know is that the main lens manufactured by Tianyuan Optical has adopted new technology and new equipment, so the price of manufacturing the main lens has been greatly reduced.

According to calculations, the final cost of this astronomical telescope will definitely not exceed one-third of the 39.3-meter ordinary optical telescope abroad, which is one-third of one billion euros, or about 300 million euros. , will never exceed 2.4 billion.
