Chapter 354: Astronomical Lens

Others also coaxed: "If Xiaoding and Xie Xiaoya change clothes in the dormitory in the future, won't they all let you see it?" ”

Xiao Ding was a little unhappy, and immediately jumped on the platform and said, "How can the camera be aimed at the girls' dormitory, because it is facing the dormitory, so I can't see it." ”

She said she was going to stop the people from peeking into the girls' dormitory.

Jin Damin shouted injustice: "There is something wrong with this shot, even if it is really facing the dormitory, there is nothing." ”

Xiao Ding took the camera and took a look, and sure enough, it was so.

Zhu Xiaohua looked through a stack of drawings drawn by Professor Shao and looked at them carefully.

He remembered that there was a set of drawings that were made up of lenses, stacked on top of each other.

After Zhu Xiaohua saw this drawing, he couldn't help but fall into deep thought. The drawings of this lens are far more complicated than expected, and it does not look as simple as just two lenses.

At this point, the student burrowed into the bellows, and soon made a new discovery.

He found that there were more than a dozen slots in the bellows for mounting lenses.

The student in charge of the optical part was the first to exclaim, "I remember, when the professor designed it, he didn't draw two lenses, but two sets of eighteen lenses!"

The professor said that he wanted to make a lens that could be adjusted from far and near, up to 10,000 times. Only in this way can you live up to such a huge size of the shoot! ”

Zhu Xiaohua was stunned for a moment, and sighed in his heart, Professor Shao really took great pains for this product.

In an ordinary photo studio, a few lenses can take clear pictures, and he can't imagine what it would be like to shoot with a dozen lenses installed.

Come to think of it, the composition of the camera for taking pictures of the starry sky should be nothing more than that.

Zhu Xiaohua set his eyes on Jin Dagui.

Jin Dagui shook his satchel, spread his hands and said, "There are only two lenses in total, which are left over from the Night City Telescope Factory a long time ago, and they haven't produced such big lenses for many years." It's not easy to sell, the price is too expensive, and there is no market at all. ”

When everyone heard Jin Dagui say this, they were immediately disappointed.

Zhu Xiaohua was also disappointed in his heart, but he was not surprised. Building a giant shoot was a very challenging task in itself, and the lens department also added a lot of ideas from Professor Shao, so you can imagine how difficult it was to implement.

Zhu Xiaohua asked the three students to remove the lenses and return them to Jin Dagui.

These two lenses have not been paid yet, only part of the deposit has been paid, and the Night City Telescope Factory promises to take it back for debugging, and if it is not qualified, it can be refunded again.

These two lenses are not cheap, one lens is almost 2,000 yuan, which is worth the price of two Seagull cameras.

Zhu Xiaohua returned the lenses to Jin Dagui and asked him to wrap them carefully before returning them to the manufacturer.

The three students looked at these two pieces of footage and couldn't help but feel sorry, and one person sighed: "I finally found a set of suitable sizes, but unfortunately I can't use them yet." ”

They are all looking forward to leaving these two lenses, and then they will find a way, because these days, this kind of lens itself is very difficult to find, and it is even more difficult to find the right size.

In the unlikely event that you can't find the right lenses after returning them, the camera will be an empty shell.

Zhu Xiaohua didn't think so, Zhu Xiaohua said: "This giant shot is Professor Shao's hard work, and the lens group is the key to the whole project, such a key equipment, there is no room for sloppiness." ”

When everyone saw that Zhu Xiaohua was serious, they immediately stood in awe and didn't dare to say more.

They just want to find the lens set as soon as possible, or find a place where they can produce such giant lenses.

Everyone turned their eyes to the outside of the hospital, looking forward to the appearance of the third of the Kim brothers.

A few hours later, Jin Yinjian, the third eldest of the Jin brothers, also rushed back.

He handed over a gray snakeskin bag to Zhu Xiaohua, and inside were several shots of long guns and short cannons.

He bought these lenses from the observatory on behalf of others, and only paid a deposit, promising the other party to pay the rest of the money if the call was qualified, and to return them if they could not be used.

Zhu Xiaohua opened the bag and took out two long cylindrical lenses from it.

These lenses are about half a meter long, and the interior is layered with lenses with a bright glass sheen.

These students saw the long barrel lens and said, "A lens made up of a dozen lenses should look like this." It's the best camera lens in the professor's mind! ”

Everyone else thinks that this time they have finally found the right one. It turned out that the lens of this giant camera was not just two pieces, but many two pieces were combined together, and it looked like a cannon barrel.

Zhu Xiaohua couldn't be happy when he saw this shot.

The heavy lens is about five centimeters in size, half the size of a giant camera. He took the lens to the giant camera and swiped twice, and the camera passed through the chamber without hindrance.

One student quipped, "It's almost as good as a bullet when this long barrel lens is put inside." ”

At that time, the hole in the front of the bellows was diagonally facing the sky, and the long tube lens was loaded from the tail, like a cannonball loaded, which could pass through the inside of the long bellows without hindrance and then pass through the front end.

Zhu Xiaohua picked up the long tube lens and glanced at it, and the scenery in the distance was clearly recognizable. Turning the twist on the lens, even the photos drying in the darkroom opposite can be clearly recognized.

Zhu Xiaohua exclaimed: "The quality of this long tube lens is really good, but it's a pity that the size is a little smaller." ”

He was a little in love with the long barrel lens, and it was almost perfect except for the size.

The two long tubes were removed from the observatory's old telescopes and cost a lot of money.

Naturally, there is nothing to say about the clarity of the photo.

And it has a lot of lenses, adjustable from far and near, which is more than enough to shoot space, stars and moon in the sky.

Xiao Ding and the others learned that the two lenses were disassembled from the astronomical telescope, and seeing that Brother Zhu couldn't put it down, they persuaded Zhu Xiaohua to stay.

The students also said: "If it is an astronomical telescope lens, the quality is naturally nothing to say." With a slight change, it can be used as a camera lens. ”

Zhu Xiaohua looked at the hole in the black hole on the bellows, and if he wanted to use these two long barrel lenses, he had to shrink the hole in the bellows by half.

One student climbed up to the hole in the front of the bellows and found foam and tape to fill it up and narrow it. Then he took the lens from Zhu Xiaohua's hand, stuffed it into the shrunken hole, and fixed it with a "clatter", the size was just right.

Immediately afterwards, Zhu Xiaohua and two other students loaded another long cylinder from the tail of the bellows.

Two long barrels were loaded, and he stood behind the lens and adjusted it, which was adjustable from far and near, and the houses and trees on the opposite side were vividly visible.

The students couldn't help but exclaim, "Now the problem of the camera is solved." ”

"Now that the camera is there, the rest of the progress will be fast."

"It's a little smaller than the professor's design, but the rest is perfect, and it's still the lens of an astronomical telescope."
