“……………… The patriarchs had a full understanding of the importance of the optical industry. As early as the Jihua period, under the care of the Executive Committee, led by the Ministry of Science and Technology, and coordinated by the Ministry of Machinery Industry, the Ministry of Metallurgy and the Ministry of Light Industry, the traversers established their own optical industry ...... from scratch."

Excerpt from "Contemporary Industrial History = Optical Industry Volume"

Of course, this kind of high-sounding cliché is directly skipped by readers. The first generation of time-travelers understood the difference between history and official history, and the descendants of the time-traveling people either knew the real story from their own parents or didn't know anything at all. Only those who have been granted high privileges to access the Vientiane Library to consult the original records know history as it is.

In fact, the beginning of the imperial optical industry was nothing more than a few old mirrors.

In the Bairen Industrial Zone, black smoke and white gas are emitted day and night, and the wheezing and vibration of machine movement do not stop all year round. There is no night here, and the fire, electric and gas lights from the boiler drive away the night. A gas-powered railcar pulls a flatbed car on the tracks, sometimes squeaking the brakes.

In a quieter corner of the industrial area, there is a machining workshop directly under the Ministry of Science and Technology. The so-called science and technology department is a "cutting-edge department" under the manufacturing director department.

By cutting-edge, on paper, the ministry is responsible for industrial products that are currently difficult to manufacture in large quantities. Traversers are either limited by the supply of raw materials, or limited by the XN energy of self-produced materials, or limited by processing capacity, so they can only use it as "pre-research". To be precise, it is the production jishu and process of Suo under the limited industrial level of Lingao.

Included in the list of "pre-research" of the Ministry of Science and Technology include various instruments, jīng secret tools and instruments, optical instruments, communication equipment, electrical and lighting equipment, timers, and so on.

The Ministry of Science and Technology is in charge of Zhong Lishi, and the official title is the People's Commissar of Science and Technology, he is a doctor, although he is not the only doctor in the Senate, but he always likes to remind everyone that he is a doctor, and over time everyone half-jokingly calls him Dr. Zhong.

Dr. Chung's main focus in the Ministry of Science and Technology is watches and batteries. Special accumulators, he has a deep research. At present, the transmission and reception systems of cable telegraphs in Lingao, Hong Kong, Sanya and other places are used in the Daniel battery or "Zhongshi No. 1" battery developed by him.

After the successful production of the "Chung's No. 1" battery, Dr. Chung's main task became a timer and radio.

These two projects were among the much-needed jīng instruments in the industrial, military, and civilian systems of Lingao. Navigation requires a jīng exact sailing clock for nautical positioning and navigation. There is also a great demand for jīng timing in industrial production. As for the radio, its importance XN is self-evident. Currently, the Senate's expatriates and out-of-country sites rely on radios brought from another time and space to maintain contact with the "center". He devoted all his time and energy to it, and also occupied several science and engineering veterans of the Ministry of Science and Technology, so that the large bells he had promised were gone, and one bell tower after another became a watchtower.

After the Ministry of Science and Technology, which was already outnumbered, shifted its personnel and resources to radios and timers, the optics program became unpopular.

The exclusive workshop area of the Ministry of Science and Technology is already close to the end of the Bairen Industrial Zone. Outside the high fence is a 50-meter-wide "warning zone" marked with bamboo fences and trenches. Bumiputes are not allowed to enter the warning zone. In order to make full use of the space, the Committee of Agriculture has opened up this plot of land as a field for planting cash crops such as castor, soybeans and jute. Most of these cash crops are supplied directly to industrial enterprises. Castor oil, soybean oil and jute are all important materials in industrial production.

"Master, you drink water." In the workshop, a young man in a blue cloth overalls respectfully brought a wooden pallet to another thin black man in a blue cloth overalls who was holding a vernier caliper to measure parts. Inside the tray was a glass bottle of light salt water and a bottle of chilled kvass. The black thin man who was called the master answered, wiped the sweat on his forehead with his sleeve, picked up the salt water and looked up to pour it into half a cup. I took a breath and drank the rest of the salt water. He picked up the kvass again, but he didn't drink it, just held it in his hand and let the palm of his hand feel the cold woman.

This kind of enjoyment was started more than ten days ago. After several efforts, Dr. Zhong finally approved the installation of a small gas cold storage at the location of the Ministry of Science and Technology, which has many relatively dense equipment and instruments, which require operation at a suitable temperature, and the use of a large amount of ice for physical cooling is essential. It takes time and effort to get ice from the large ice storage of the food factory every day, not to mention the loss on the road. With this freezer, it not only meets the needs of production, but also has such a little enjoyment.

"Junjie, don't be busy, let's take a break. The body is important on this hot day. Looking at the young man's work clothes, which had been blackened by sweat, the black thin man said.

On the other hand, the young man had already taken down the tray and picked up the fan, and was fanning the master: "I'm not tired, master, you rest." ”

"Everybody's on break." The master picked up the workpiece he had just made and squinted his eyes to carefully examine the sunlight cast on the skylight.

"The craftsmanship is good, and you will be able to take charge of your fitter skills in a few more years.

"It's all the leaders who teach well." The apprentice said respectfully, "My father's skills are much better than mine, if it weren't for his bad eyes, he would definitely be better than me." ”

"It's a pity." The master was silent for a moment. He knew his apprentice's father, a man in his 40s, whose eyes had grown old due to long-term malnutrition and heavy work in the past.

"Thanks to the chief, my whole family would have starved to death." The apprentice spoke more and more respectfully.

The master waved his hand. "Don't talk about that."

He knew that his apprentice's family was a fugitive Shandong artisan household, and the family of six had fled all the way to Guangdong and became homeless, leaving only his father and two boys. If it weren't for the Guangzhou station, the three people who were already struggling on the death line would not have survived to this day. The eldest child entered the factory to be an apprentice with him, the younger one went to school, and the old one, although he had a haode skill, had bad eyes, and could only do what he could in the factory of the Ministry of Light Industry.

After work that day, the master walked in front with his hands behind his back, and the young attendant carried a bag, a cleaned lunch box, and a kettle in the back.

"Lao Lin! Lao Lin! "Someone in the back is shouting." Lin Hanlong! ”

Lin Hanlong turned around, it was Wu Jin, a colleague from the Ministry of Science and Technology.

Wu Jin is a "masturbator", he, like Mei Lin, Ji Xin, Cui Yunhong and others, is one of the very few adult male xn veterans who have not bought NV servants so far - in Lingao... The vast majority of the adult senators, including the NV veterans, have purchased NV servants. So their difference is particularly striking. Although the reasons why they don't buy NV servants are varied, some people have no "xn interest" in NV people, some have temporarily lost interest, some have different aesthetic tastes, and some "would rather solve it themselves than make do"... Wait for a haodenv servant to come out and buy it later.

Xiao Bailang once got drunk at the farm café, so he gave them to a single independent party called "Masturbation Party". And so the term spread.

Wu Jin is a recent graduate of a master's degree in electrical engineering in the old time and space. It is the professional aspect of power cables. He has interned in cable factories and transformer factories as well as substations, and is familiar with the cable production process, but his practical experience is limited, and he does not have half a bucket of water. In the Ministry of Science and Technology, he engaged in "power equipment development". He was also a regular of the Senate office football team, playing as a left wing-back.

Lin Hanlong saw that he was carrying a bag of dirty clothes, and there was a strong smell of sweat.

Remembering that he was going to coach the football team of the Ministry of Science and Technology today, and under the strong advocacy of Chen Sigen, football, rugby and bāng ball began to be promoted from schools to various ministries of industry, agriculture and administration.

"Have you watched 88s? The Navy guys are clamoring for a fire control system on board. He said excitedly..."I want to build a mechanical fire control computer!" It's really exciting. ”

"Fire control? The telescope hasn't been taken out yet. It's really an army and a navy, and we can't catch up with the momentum of thousands of miles in one day. ”

"Speaking of which, you studied optics, right? That's what you do. ”

Lin Hanlong smiled bitterly. "What haven't I done in Dongguan? Mobile phones, computers, digital cameras...... I've done all kinds of knockoffs. To say that general optical instruments are not rare, the problem is that we don't even have optical glass, what to do. With those few bureaucrats who are already very decent, it would be good to be able to think of this stubble after one or five jihuanòng. ”

That's not bragging... Since graduating from a second-rate university, Lin Hanlong has been working as an "engineer", "senior engineer", "jishu manager" and so on in small power plants in the Pearl River Delta for a long time, and his main work is to make copycat mobile phones, copycat computers, copycat this, and DK in various copycat power plants in the Pearl River Delta. From notebook digital cameras, there are almost no consumer appliances that he hasn't worked on. He has also been in contact with optical instruments and electrical equipment to a greater or lesser extent.

"It won't be without optical glass, right? I remember that the patriarch could wear glasses.................."

At the time of the crossing, considering that there were many myopic eyes among the elders, although some people went for myopia correction surgery before D, many people had doubts about corrective surgery... Unwilling to toss. For this reason, when making a list of materials and equipment, we also deliberately brought a full set of optometry and lens grinding equipment and a large number of resin and glass optical lenses. Make sure you can fit a variety of glasses for the veteran for decades. The elders with shili problems often also brought their own spare glasses that were enough for a lifetime.

"How much can that... These optical equipment and supplies were prepared for 500 people, and now they are equivalent to serving hundreds of thousands of people... How is it enough? ”

Lin Hanlong shook his head and said goodbye to Wu Jin. After returning to the dormitory, he unusually did not eat, bathe, play cards and watch movies, but ate in a hurry, took out the professional manual that had been dusty for many days and looked through it. His NV servants didn't dare to disturb him, but filled him with tea and water from time to time.

During the lunch break the next day, Lin Hanlong found a glass plate to make flat glass, which is not a rare commodity. There are workshops in warehouses. Lin Hanlong Jīng carefully selected, searched almost all the glass plates in the inventory of the Ministry of Science and Technology, and selected the glass plates that were clarified and had no sè.

With a stroke of the iron ruler, he turned it over and laid it flat on the wooden board, aimed the edge of the wooden board, and gently knocked on a long strip of glass to come down. After a few strokes, the strip turned into eight one-inch square pieces of glass.

In the afternoon, Lin Hanlong found a time to take his apprentice to the general warehouse of material preparation at the industrial entrance. All kinds of modern materials are the objects of strict supervision by the Planning Institute, and no one wants to take out a screw or a wrench without a few signatures. But the traversers are much more casual about what they can produce on this plane.

As long as the ordinary materials in the warehouse are below a certain limit, the elders of the industrial port can directly fill in the picking list and sign to receive. He nodded to the steward of the warehouse, and a middle-aged naturalized storekeeper immediately ran over.

There is no easy job in Lingao, and in addition to managing the warehouse, the warehouse manager also has to play a cameo role as a porter. When you are free, you can do some manual work that does not require equipment. These are all included in the work quantification. The former sweatshop in the planning yard often checks the efficiency and amount of work for each type of work to make sure that no one is idle.

Lin Hanlong's apprentice didn't wait for the order to push a "purple electric reform" to the side, and followed Lin Hanlong and the warehouse manager into the warehouse.

The general warehouse of the industrial port used to be just a shed... Near ォ renovated into a standard library of red brick forged iron truss structure. The top layer is also covered with a thermal insulation layer under the slab tiles. The sun was scorching outside, and when I walked into the tall and deep warehouse, I immediately felt a chill, and the sweat disappeared a lot.

The preparation warehouse is divided into several warehouses according to the type of material stored, and the wooden and iron shelves are densely arranged, and the various materials are piled up on them. These are all collected, produced, and processed in this time and space.

Lin Hanlong knew where he wanted something. He walked straight to the shelves and pointed to the number. The apprentice immediately stepped forward and moved to the car, and the warehouse manager filled in the form on the writing board accordingly. After a while, Lin Hanlong had already gotten all the things he wanted. The three of them returned to the outside of the warehouse. Lin Hanlong and the warehouse manager entered the office, the warehouse manager returned to his desk and began to copy the bill of materials in triplicate, and someone came over to serve tea to Lin Hanlong, and his apprentice pushed the cart and waited outside. After a short time to complete the copying of the material list, the warehouse manager sent the material list to Lin Hanlong for him to sign, and then submitted it to the steward for sealing. In addition, someone is responsible for checking that the bill of materials matches the number and type of things on the car, and then there are three chapters.

Back in the workshop, Lin Hanlong told the apprentice that he would work overtime today... Then I got down to business. As an all-rounder, there are countless things waiting for him in the Ministry of Science and Technology. He had to wait until after work in the evening to get busy with this idea.

The whistle sounded after work. Lin Hanlong found a suitable gas stove and set up an iron pot on it. In the iron pot is the freshly received beeswax and rosin, which are put into the pot in proportion, which is the binder of the glass.

He turned on the gas fire and waited patiently for the hún compound to melt and stir well... Scoop out some with an iron spoon and pour it onto a piece of glass, then press it with another piece of glass. In this way, all the glass pieces are glued together.

Lin Hanlong removed the iron pot, added an iron cover to the stove, and took out another iron plate to put on the shelf. Heat the iron plate over low heat. Seeing that the heat was almost over, Lin Hanlong put on heat-proof gloves, put the glass attached together on the iron plate to let the adhesive melt again, and then put it on the screw press, carefully rotated the handle to press the glass pieces together and then fixed them with a clamp.

Waiting for the glass to completely solidify, he went outside to smoke a cigarette and blew the evening breeze in Lingao. chōu finished smoking... Another cup of tea.

After all the glass pieces are tightly pressed together... The edges are all aligned to form a glass cube. nòng finished these... He drew a cross line at both ends of the long axis of the cube to find out the center, and then used the ink circle to draw two circles, one large and one small, and then dripped some melted adhesive to glue two small cylindrical iron pieces to the two ends of the glass, which happened to cover the small ink line circle.

Lin Hanlong asked his apprentice to clean up the furnace and paced to the side of the grinder with a glass cube. Because it was already off work, the grinder was not used. This grinder, from the grinding wheel to the machine, was brought from the old time and space. Lin Hanlong suddenly remembered that Zhong Lishi had said that there were too many things to develop the grinding wheel, so let's talk about it later.

He carefully clamped the glass and started the grinder. The first step is to cut off the four edges of the cube, and the cross-section changes from a square to an octagonal shape. Then continue to cut, and the octagon becomes hexagonal. I did it very carefully every time, the feed was very slow, and the coolant was always on. Seeing that it was almost the time to draw the haode circle earlier, Lin Hanlong began to rotate the workpiece, and it was very easy to grind out a decent cylindrical shape. He turned off the grinder, took out the workpiece and measured it for a long time, and when he was satisfied, he put everything away and beckoned his apprentice to get off work.

On the third day, Lin Hanlong Jiāo gave his apprentice a task, asking him to use a hammer to smash all the garnets he received into powder, and then use iron balls and iron mortars to grind them as fine as possible. Garnet was discovered by a remote exploration team while working in the field, and because they knew that this thing was useful in industry, they brought back dozens of kilograms of samples.

Garnet has a relatively high hardness, and the ancients used it as an abrasive to process yù stone, which is also a gemstone itself.

Gem-quality garnets are among the mid-to-high-end gemstones. Industrial grade garnet is used in many ways, because it has a hardness of 7, so it is mainly used for grinding materials and cutting materials. The long-range exploration team mined these garnet sands, which can only be considered industrial grade. The texture is impure, containing a lot of impurities, and the face is not pure.
