Chapter 3 Hand-Rubbing Lenses
Chapter 3 Hand-Rubbing Lenses
As the saying goes, you can’t chew too much,
After the excitement, Kang Chi did not immediately build an aircraft carrier, but placed an order online to purchase a batch of optical plastics and aluminum powder needed for coating.
It is more realistic to be honest and rub the lenses first.
Next, Kang Chi still has an important doubt to solve.
How to get mastery points?
This is a good thing, which can save a lot of research and development funds!
Unfortunately, Kang Chi studied for half an hour and didn’t figure it out. As the sky darkened, he had to pack up the shop and prepare to go home.
”Alas, it’s another day of low income.”
When closing the door, Kang Chi couldn’t help but sigh that business is not easy now.
However, it is normal to be closed for a day when doing equipment maintenance.
These equipments are usually very valuable, and most of them are treated like fathers after they are bought. How can they be easily broken?
Compared to repairing, reselling second-hand goods can make money faster.
But Kang Chi is not suitable for this kind of reselling speculation business, and he also looks down on it…
On the way home, Kang Chi bought a single meal at Wallace, ate while walking, and solved the dinner by the way when he got home.
The first thing he did when he got home was to take out the upgraded lens, sit down at the workbench at home, and start to disassemble and analyze this lens.
Although he thought that the structure of this manual fixed focus lens would definitely not be very complicated, Kang Chi would take photos and record every time he disassembled a part for safety reasons.
Soon, the desktop was filled with various parts and small screws.
This structure…
It is much more complicated than what he made himself!
After the initial disassembly, Kang Chi had a certain understanding of the structure of the lens.
The next step was to draw drawings for these parts and make further careful analysis.
To fully understand a product, you must know not only what it is, but also why it is.
As time passed, Kang Chi’s eyes became brighter and brighter.
Although there was no laboratory verification and no precise digital simulation calculation, Kang Chi had already gained a lot of inspiration and inspiration from the arrangement order and parameters of the optical components.
However, this epiphany was more of a craftsman’s intuition and lacked systematic and scientific arguments.
”There is still a lot to learn!”
Kang Chi sighed, put away the drawings, and immediately ordered a few basic optical books online.
After doing all this, he reassembled the lens based on his memory and understanding of the drawings.
Hu——
With the last screw tightened, the lens was successfully assembled, and the familiar panel appeared again.
[Item: Daqin Optics 50mm F1.4 Lens]
[Manufacturer: Kang Chi]
[Item Level: 2]
[Experience: 135/400]
[Mastery Point: 0.3]
[Item Status: Intact, Resolvable]
Wait?
”Mastery Point 0.3?”
Kang Chi was immediately excited when he saw a number on the panel change.
After using the only mastery point in the afternoon, the number was always 0, but now it became 0.3…
Could this mastery point be obtained through learning or disassembly? Kang Chi immediately found a copy of “Mechanical Design: Basic Principles, Drawing and CAD Technology” and read it carefully.
Half an hour later, Kang Chi picked up the lens again and looked at the panel.
【Mastery Points: 0.31】
It really works! But what the hell is 0.01?
Is it an encouragement award for studying hard?
emm~ It may also be because I didn’t look at it carefully enough and learned too little? Next, Kang Chi disassembled and assembled the lens very carefully.
【Mastery Points: 0.33】
This is also OK, and it seems to increase a little more than reading a book.
Anyway, Kang Chi finally figured out this system! As long as you gain new knowledge through learning, or gain practical experience through manufacturing, maintenance and other methods, you can increase your mastery points!
Kang Chi happily put down the lens and couldn’t help yawning.
Looking at the time, it was already twelve o’clock without realizing it.
The body is the capital of revolution, and with the golden finger, it will soon be bigHe didn’t want to die again.
Kang Chi immediately went to wash and sleep to conserve his energy for the next day’s battle.
The next day.
The streets were filled with faint morning mist, and the whole city seemed to be still asleep.
Several groups of extras who got up early but were not selected by the crew were still squatting on the roadside eating steamed buns, staring at every passerby and car.
Once upon a time, Kang Chi also wanted to be an actor, but as he grew older, he lost interest in this kind of gambling-like career.
Especially after experiencing the rise of short videos and live broadcasts, he was even less interested in seeing the mess after the ebb tide.
I am an honest man.
Hard work is the traditional virtue of the Chinese people!
Kang Chi silently gave himself a thumbs up, opened the shop and started a new day of business.
Except for a few equipment rental stores that are manned 24 hours a day, Kang Chi is probably the first one to open on the whole street.
Mainly because he usually goes to bed early and gets up early, and he is single, what else can he do except come to the store early to knock and bang? Just after Kang Chi finished rubbing a 50mm fixed-focus lens, a courier knocked on the door and walked in.
”Boss Kang, your courier.”
Kang Chi quickly stopped his work, took the courier and looked at it, and it was indeed the material ordered yesterday.
Although they were all looking for suppliers in the same city, the efficiency is also worth praising.
”Thank you, can you wait a moment, I just have a lens to send.”
Seeing the courier nod, Kang Chi quickly packed the lens he had just rubbed and sent it to the art student.
After the courier left, Kang Chi immediately opened the package, confirmed that the materials inside were fine, and began to try to make a doublet achromatic lens in front of the workbench.
The optical resins he ordered were all in the shape of blocks. The first thing to do was to grind out the shape of the lens, then polish, coat, and finally stick the concave lens and the convex lens together.
This process sounds easy, but it is extremely difficult to operate in practice, especially to grind the curved surfaces of the convex lens and the concave lens to fit perfectly, which is a great test of hand skills.
If it follows the normal production process, this should be done with a high-precision processing machine tool, or with a high-precision mold to directly shape the material for a second time.
But Kang Chi doesn’t have this condition now, so he can only rely on hand rubbing.
The main feature is dexterity! After marking the material with a pen, Kang Chi skillfully turned on the grinder and began to make the lens according to the drawings he drew last night and his own experience.
The first time, the gap between the two lenses was big enough to fit two pages of paper.
The second time, more than a dozen bubbles appeared when gluing them together. The third time, the fourth time…
After more than a dozen attempts, Kang Chi finally succeeded in getting a doublet achromatic lens!
He picked up the lens excitedly and saw that a panel popped up on it.
[Item: Doublet Achromatic Lens]
[Manufacturer: Kang Chi]
[Item Level: 1]
[Experience: 0/100]
[Mastery Points: 1.35]
[Item Status: Intact, Can Be Parsed]
I actually got 1 full mastery point, which is simply wonderful! (End of this chapter)
