Technological power starts with upgrading lenses

Chapter 3 Rubbing the lens by hand
As the saying goes, bit off more than you can chew.

After getting excited, Kangchi did not immediately build an aircraft carrier. Instead, he placed an order online and purchased a batch of optical plastics and aluminum powder needed for coating.

It’s more realistic to be honest and rub the lens first.

Next, Kang Chi still has an important question that remains to be solved.

How to get mastery points?

This is a good thing, it can save an unknown amount of research and development funds!

Unfortunately, Kang Chi couldn't figure out the reason after studying for half an hour. As the sky got darker, he had no choice but to pack up the shop and prepare to go home.

"Hey, it's another bad day for income."

When it closed, Kang Chi couldn't help but lament that business is not easy to do now.

However, it is normal to be closed for a day for equipment maintenance.

These equipments are generally valuable, and most of them are provided like fathers after buying them. How can they be damaged easily?

Compared with repairs, reselling second-hand goods can make money faster.

But Kang Chi didn't like this kind of reselling and speculation business.

Just like he looked down on those anchors who graduated from prestigious schools but went to live broadcast and sell goods,
If you obviously have a craft, or are intellectually talented, but if you do something that you can do just after graduating from junior high school, wouldn't it be a waste of the cultivation that the country and society have given you?
Isn’t it good to make the money you deserve?

On the way home, Kang Chi bought a meal for one person at Wallace, ate while walking, and had dinner on the way when he got home.

The first thing I did when I got home was to take out the upgraded lens, sit down at my workbench, and start disassembling and analyzing the lens.

Although I feel that the structure of this manual fixed-focus lens is definitely not very complicated, for the sake of safety, Kangchi will take photos and records every time a part is disassembled.

After a while, the table was filled with various parts and small screws.

This structure...

It’s much more complicated than what he did himself!

After completing the preliminary disassembly, Kangchi already had a certain understanding of the structure of the lens.

The next step is to draw drawings of these parts and conduct further detailed analysis.

To understand a product thoroughly, you must know what it is and why it is so.

As time passed slowly, Kang Chi's eyes became brighter and brighter.

Although there is no laboratory verification or precise digital simulation calculation, Kangchi has obtained a lot of inspiration and inspiration from the order and parameters of the optical components.

It's just that this kind of epiphany comes more from a craftsman's intuition and lacks systematic and scientific argumentation.

“There’s still a lot to learn!”

Kang Chi sighed, put away the drawings, and ordered a few basic optical books online.

After doing all this, he reassembled the lens based on his memory and understanding of the drawings.

call--

As the last screw was tightened, the lens was successfully assembled and the familiar panel appeared again.

[Item: Daqin Optics 50mm F1.4 lens]

[Manufacturer: Kangchi]

[Item level: 2]

【Experience: 135/400】

[Mastery Points: 0.3]

[Item status: intact, parsable]

and many more?

"Mastery point 0.3?"

Kang Chi suddenly became excited when he saw a number on the panel change.

After using the only mastery point in the afternoon, the number has always been 0, but this time it became 0.3...

Is this mastery gained through learning or dismantling?
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 camera and looked at the panel again.

[Mastery Points: 0.31]

It really works!But what the hell is 0.01?

Good study encouragement award?

emm~
Or maybe it’s because I didn’t watch it carefully enough and learned too little?
Next, Kangchi conducted a very serious disassembly and assembly of this lens.

[Mastery Points: 0.33]

This is okay, and it seems to increase a little more than reading a book.

In any case, Kang Chi finally understood the system!
As long as you gain new knowledge through learning, or gain practical experience through manufacturing, maintenance, etc., you can increase your mastery points!

Kang Chi put down the camera happily and couldn't help but yawned.

Looking at the time, it was already twelve o'clock before I knew it.

The body is the capital of revolution, and with Golden Finger on the verge of making great achievements, he doesn't want to burp again.

Kang Chi immediately went to wash up and go to bed to recuperate for the next day's battle.

The next day.

A faint morning mist filled the streets, 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, and eagerly looking at every person and car passing by.

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, I am even less interested when I see the mess after the tide recedes.

I am honest.

Working hard is the traditional virtue of the Chinese people!

Kang Chi silently gave himself a thumbs up, opened the store and started a new day of business.

Except for a few equipment rental stores that are staffed 24 hours a day, Kangchi is probably the first to open on the entire street.

Mainly, he goes to bed early and wakes up early naturally. He is single, so what else can he do besides coming to the store early to knock around?
Just after Kang Chi finished rubbing a 50mm fixed-focus lens, a delivery boy knocked on the door and walked in.

"Boss Kang, your express delivery."

Kang Chi quickly stopped what he was doing, took the express delivery and looked at it. Sure enough, it was the materials ordered yesterday.

Although we are looking for suppliers in the same city, the efficiency is worthy of praise.

"Thanks, can you wait a moment? I just have a lens to send."

Seeing the courier boy nodding, Kang Chi quickly packaged the lens he had just cut out and sent it to the Academy of Fine Arts student.

After the courier boy left, Kang Chi immediately opened the package. After confirming that the materials inside were OK, he began to try to make a double achromatic lens in front of the workbench.

The optical resins he ordered were all in square form. The first thing to do was to grind out the shape of the lens, then polish it, coat it, and finally glue the concave and convex lenses together.

This process may not sound difficult, but it is extremely difficult in practice, especially polishing the curved surfaces of the convex and concave lenses to a perfect fit, which is a test of your skills.

If we follow the normal production process, this should be done using high-precision processing machine tools, or using high-precision grinding tools to directly reshape the material.

But Kang Chi doesn't have this condition now and can only rely on hand rubbing.

The main thing is ingenuity!
After marking the material with a pen, Kang Chi skillfully turned on the grinder and started making lenses based on the drawings he drew last night and his own experience.

For the first time, two pages of paper can fit into the gap between the two lenses.

The second time, more than a dozen bubbles appeared during gluing.
Third time, fourth time...

After more than a dozen attempts, Kang Chi finally succeeded in getting a double achromatic lens!

He excitedly picked up the lens and saw a panel popping up on it.

[Item: Double Achromatic Lens]

[Manufacturer: Kangchi]

[Item level: 1]

【Experience: 0/100】

[Mastery Points: 1.35]

[Item status: intact, parsable]

I actually got a full 1 mastery point, which is simply wonderful!
