Chapter 1115 Clairvoyant Eye
Zhou Qun was somewhat depressed.

He was very confident in his new design and felt that it would definitely surpass the transmission telescope.As long as Tongtong gets the support of the emperor and orders Shangfang to supervise the trial production, it will be successful soon.

But he didn't expect that the emperor couldn't see the beauty of it. Not only did he not order Shangfangjian, but he also asked him to cooperate with the workshops in Nanyang to win their support.

This is no different from perfunctory.

He used to admire the emperor very much, but now he feels that the emperor is not so wise.

Unhappy, she went out of the door and came to the vestibule, where she was stopped by Qin Mi who was waiting here.

Qin Mi was worshiped as a minister and was on duty today. When Zhou Qun came to see him, he waited in the vestibule, wanting to chat with him about recent developments.Speaking of which, he strongly invited Zhou Qun to enter the court, and now that Zhou Qun is flourishing in the Taishi Department, he is also happy.

Seeing Zhou Qun depressed, Qin Mi was a little surprised, led Zhou Qun to a remote place, and asked a few words.

Zhou Qun explained the situation again, and then complained: "I have done experiments, the reflection has no chromatic aberration, and it is better than the transmission mirror, so it can be made bigger, but it is not bulky, and it is hundreds of times better than the transmission mirror. Knowing the beauty of it, it is not allowed."

Qin Mi didn't speak immediately, but after thinking carefully for a while, she asked Zhou Qun to spread out the drawing and shook her head.

"Brother Zhongzhi, with all due respect, your design is indeed brilliant, but there are also many difficulties. Among other things, the reflection of this bronze mirror is not as bright as the transmission, and it is obvious to all. It may be reluctant during the day, but at night..."

Qin Mi didn't continue, but Zhou Qun understood, slapped his forehead, and said dejectedly: "Neglected, negligent."

Bronze mirrors are commonly used, so Zhou Qun naturally understood that what Qin Mi said was reasonable.He wanted to build this telescope for stargazing, all at night.It's still blurry in a room, not to mention the stars thousands of miles away in the night sky?
In this way, when the emperor asked him to discuss cooperation with Nanyang Workshop, it was not perfunctory, but a polite refusal.

Qin Mi didn't think so.

He told Zhou Qun that there are many mirror workshops in Nanyang. They not only make telescopes, but also copper mirrors for daily use.Because of the fierce competition, they put in a lot of effort. Some workshops worked hard on grinding, while others spent a lot of thought on materials. They all came up with new ideas to win, and improving the reflective brightness is one of them.

In this regard, non-governmental workshops have more experience and ideas than Shangfangjian.

After hearing this, Zhou Qun was skeptical, but still went to prepare.

A few days later, Zhou Qun published the article first, and then the Taishi Department called several powerful workshops in Nanyang to participate in the meeting in the name of seminars to seek collaborators.

As Qin Mi said, several mirror-making workshops were very interested, and one of them proposed a solution to the lack of brightness.

Using silver as a mirror, or plating a layer of silver on a copper mirror, and then grinding it, the brightness can be improved by several levels.

This, they have tried.It's just that the cost of silver plating is too high for ordinary people to afford, so it can only be sold as a luxury item at present.If it can be labeled with the Taishi Department, it may help to increase its popularity.

Of course, rather than the labels of the Taishi Department, they hope that their own products can become tributes, so that the queens and nobles in the harem can use this high-brightness silver mirror and publicize it for them.

The two sides hit it off.

Zhou Qun patted his chest and said, I will report your request to the emperor and try to get his approval.

The representative of the workshop was very happy, and when he went back, he was sent a beautiful silver mirror with two sides.Zhou Qun immediately sent the two silver mirrors to Liu Xie.

Liu Xie was also surprised by the cleanliness and brightness of the silver mirror.

Nanyang is worthy of being the hometown of an emperor. There are many rich people and various crafts are developed. To be able to manufacture such a delicate and clean silver mirror with such a high reflectivity far exceeded his expectations.

It seems that it is necessary to conduct a thorough investigation of Nanyang's technological level.

Such a bright silver mirror should be no problem for making reflecting telescopes, and Zhou Qun is one step closer to his goal.

Of course it's just one step.

Although the reflecting telescope can solve the problem of chromatic aberration, it cannot solve the problem of spherical aberration. There is still a long way to go to build a qualified astronomical telescope, and even he cannot solve it.

He is also not very clear about those details, and can only count on more people to explore.

Liu Xie politely rejected the workshop's idea of ​​becoming a tribute and promoting it in the name of the court.

He told Zhou Qun that the imperial court had no money, and the size of the harem was reduced as much as possible, so they could not afford too many luxuries, and he did not want to create an atmosphere of extravagance.I can provide part of the cost of your telescope development, and the tribute will be avoided.

Zhou Qun didn't care either.

As long as it can be made into a telescope, he doesn't care about the rest.Besides, the emperor practiced frugality, and he couldn't get what he wanted, and there was absolutely no reason to persuade the emperor to be extravagant.

Save money, just use it for research.

After repeated negotiations, the workshop also gave in, and signed a cooperation agreement with the Taishi Department to jointly develop telescopes dedicated to stargazing.

After more than a month of hard work, the first reflecting telescope came out.

There is no chromatic aberration, and the brightness is acceptable, but the effect is not as good as Zhou Qun expected. The images of the stars are blurred and not as clear as the transmission telescope.

Zhou Qun was hit hard, thinking hard.

At this time, an article was published in the Di newspaper, predicting Zhou Qun’s previous article, mentioning that when the spherical surface is small, image deformation and blurring outside the axis will occur, and a possible solution is proposed mathematically.

Zhou Qun was shocked after reading the article, and immediately found the young scholar named Zhao Shuang and invited him to participate in the development of the reflecting telescope.

Compared with Zhou Qun's troubles in developing the reflective telescope, Shang Fangjian's development of the transmissive telescope has been relatively smooth.After solving the material problem, a telescope that meets military requirements was quickly developed, expanding the field of view by two to three times.

After acceptance, Liu Xie ordered the manufacture of the first batch of military telescopes, a total of twenty.

Ten of them were handed over to the martial arts hall for teaching and practice, and Shangfang Supervisor was used to provide feedback.

The ten are numbered with heavenly stems and distributed to the generals who fight on the front line and some important generals who guard one side. They are not only combat weapons, but also a kind of honor.

For example, although Hussar General Zhang Ji broke away from the front line, he also got a telescope, numbered B.

Knowing that there were only ten generals who got the telescope, and he was one of them, Zhang Ji was inexplicably grateful, and immediately expressed his thanks.

Also thanking Han Sui, numbered Ding.

Han Sui supervised and led the two states of Yanyu, but he had no combat missions.After receiving the telescope, he knew that the court had not forgotten him, and the emperor had not forgotten him. He was in a good mood and wrote a warm thank you letter with his own hand.

Ding Chong, the new General Zhengnan who formally succeeded Zhang Ji, also received a telescope, numbered Geng.

There are tens of thousands of troops in the entire Jingnan area, only Ding Chong has been rewarded, and the court's support for him is very firm.After Ding Chong received the telescope, he expressed his gratitude and sent someone to deliver the telescope to Sun Ce's army, saying that Sun Ce needed such a sharp weapon more than he did, and he could lend it to Sun Ce first.

After receiving the telescope, Sun Ce was very satisfied, and immediately wrote back. In addition to thanking him, he reiterated his support for Ding Chong, and said that all preparations have been made, and he can enter Jiaozhou after autumn.
