When these visitors came to Zhang Yi and others, they were very confused when they saw such a large telescope on their booth.

You must know that no domestic manufacturer can build such a large ground-based telescope except for a few state-owned manufacturers that did not participate in the exhibition.

Even if a state-owned manufacturer builds such a large-diameter telescope, it will be very difficult. You must know that the nominally largest ground-based optical telescope in China is a 4-6 meter spectral survey telescope, and it is still the kind that cannot image.

So although some people came to Zhang Yi's booth, they basically turned a blind eye to this six-meter telescope and pretended they hadn't seen it at all.

Because no one believed that Colorful Stone, as a manufacturer that had just entered the ranks of telescope production, could produce such a ground-based telescope in such a short period of time. Everyone regarded this telescope as the goal that Colorful Stone wanted to achieve in the future.

.

After seeing the puzzled faces of these visitors, Zhang Yi also understood why, because the telescopes of other domestic manufacturers were all under one meter, and Zhang Yi and his colorful stone astronomical telescopes except for various telescopes under one meter on the exhibition stand.

In addition to the complete range of apertures, there are also three telescopes with a diameter of more than one meter on the booth, namely 1.2 meters, 1.5 meters and the largest one with a diameter of 6 meters.

It is no wonder that they would regard this as the target of the colorful stone telescope, because no domestic company can make these telescopes over one meter, especially the six-meter one.

Just when Zhang Yi wanted to ask the staff he brought to explain to the visitors, he found a large group of people in the distance walking towards the exhibition platform of domestic manufacturers.

Zhang Yi also knew some people in this group, namely the two people from the Astronomical Association who went to their Qicai Stone Machinery Factory last time. Besides them, there were several people in this group who were relatively familiar with Zhang Yi.

Of course, this is just that Zhang Yi knew them, and they did not know Zhang Yi, because they were government officials in Hangzhou, and he even saw the mayor of Hangzhou in them. It was obvious that this group of people was the organizer of this exhibition.

square.

However, Zhang Yi can also see from this that Hangzhou attaches great importance to this astronomical instrument exhibition, otherwise as the mayor of Hangzhou, he would not come here.

At the same time, there was a large group of people around them who were carrying various guns and cannons and following the organizers. These people carrying guns and cannons were journalists from all walks of life who were indispensable in any big scene.

.

The staff of these organizers first went to the booths of major domestic well-known telescope manufacturers and looked at their products.

Then, they visited less famous manufacturers like Zhang Yi and his colorful stones, but when this group of people came to Zhang Yi and his booth.

They were also very confused. They had to know that they had never seen such a huge telescope before in the entire exhibition. Even when they visited the Galilee Astronomical Instrument Company abroad, their largest telescope was only two meters in diameter.

Moreover, although their telescope has an aperture of only two meters, its base is very large, at least larger than Zhang Yi's, and it is also overweight, reaching forty or fifty tons.

"You are the exhibitors of Qicaishi Machinery Factory! Is this telescope the future goal of your factory? But if you want to make a telescope with such a caliber, I can only say that you are brave, but it is unrealistic.

Let’s not talk about whether the country has the ability to produce the optical glass required for large-diameter astronomical telescopes. Just grinding such a huge lens is not something a small business like you can do. After all, manufacturing such a telescope requires a lot of money.

It is measured in billions.

So I advise you not to aim too high and build a small-diameter telescope first." When everyone came to Zhang Yi's booth, an elderly man in the crowd said after looking at Zhang Yi's exhibits.

"Hello! Old gentleman! The target of our colorful stone is not a six-meter telescope, and this telescope is not a sample. This is a real large-diameter astronomical telescope." After hearing this, the old man

After that, the staff of Colorful Stone Telescope said.

"That's right. You should set your goals smaller first... Wait, what did you say?

The 6-meter telescope of your Colorful Stone is a ready-to-use telescope, not a sample. How is this possible?

We must know that our Dahua Empire did not pay much attention to this aspect in the past, so even now our state-owned enterprises are very difficult to manufacture such a large astronomical telescope.

As a private enterprise, how can your Qicaishi Machinery Factory manufacture a telescope with such a large aperture? Otherwise, the telescope in your factory is imported, or the imported lenses are assembled by yourself." The old man listened to the introduction of Zhang Yi and his factory employees.

After that, I was a little shocked, and then I seemed to have figured out something.

In fact, what the old man said is not a new thing in China, but a phenomenon that is common in all walks of life. For example, when the old man was talking just now, several manufacturers next to him had ugly expressions because

The lenses used in their telescopes are imported.

"Old gentleman! I don't know your name, and I don't know what other domestic telescopes are like.

But for our colorful stone telescope, every screw, nut, every part, and even every piece of material on it are made bit by bit by ourselves.

Everything in the entire telescope is produced by ourselves, and there are no parts imported from abroad." The staff continued to say to the old man.

"Impossible! This is absolutely impossible. As far as I know, no company in our country seems to have such capabilities, especially in lens manufacturing." The old man said in shock,

At the same time, the group of people who came with the old man were very shocked, including the mayor of Hangzhou.

After all, for this Hangzhou Astronomical Instrument Exhibition, the mayor and various officials of Hangzhou have specially learned about this aspect before, so they also have some understanding of the current situation of domestic astronomical instruments, especially the most widely used astronomical instruments.

telescope.

"Old sir! It's not impossible. Just because other people in the country can't produce it doesn't mean that we, Colorful Stone, can't produce it. Even if it's the lenses and optical glass needed for astronomical telescopes, we, Colorful Stone, have completely solved the problem.

However, due to time constraints, our telescope is just an ordinary optical telescope and cannot yet perform optical imaging and infrared imaging. If we are given some time, we can also manufacture these things, and then this telescope will be considered a
Chapter completed!
