Lin Gao Qiming

Chapter 918 Optical Products
"Look, a 50mm magnifying glass, F quarter." Lin Hanlong took out the magnifying glass and handed it to Wu Nanhai.Wu Nanhai casually picked up the writing paper on the table and looked at it with a magnifying glass.

"Well, did you do a good job? It's very clear." Wu Nanhai clicked his tongue, and stroked the handle of the magnifying glass with his hand, "If it wasn't for the wooden handle, I would have thought we had brought it."

"Advanced magnifying glasses are mostly made of natural materials, and wood is just one of them."

Wu Nanhai put down the magnifying glass and nodded. "Okay, no problem at all. The more our agricultural department is interested in this kind of thing, the better." He turned around and greeted the naturalized workers, "Go, bring the bill of lading, and let them go through the delivery procedures."

"Very well, this will settle the two."

"By the way, the sugar meter I mentioned last time, you said it's ready?" Wu Nanhai's voice became serious as he said this, which was the real purpose of his visit.

"Oh, that." Lin Hanlong took out a box from the drawer with a nonchalant expression. "I made one. You see."

The sugar meter is a rapid detection instrument using optical principles, which is specially used to quickly determine the concentration or refractive index of sugar-containing solutions and other non-sugar solutions.It plays an important role in sugar, food, beverage and other industrial and agricultural production fields.In addition to measuring sugar content, it can also be used to measure the concentration of various sauce products such as soy sauce and tomato sauce.In agricultural production, it is suitable for determining the exact harvest time of fruit and sugar crops, and for sweetness classification.

The principle is that light will be refracted when it enters another medium from one medium, and the ratio of the sine of the incident angle is constant, and this ratio is called the refractive index.The content of soluble solids in fruit and vegetable juices is proportional to the refractive index at the same temperature and pressure. By measuring the refractive index of fruit and vegetable juices, the concentration of fruit and vegetable juices can be obtained.

The sugar meter that Wu Nanhai took out was basically like a sugar cane with one end beveled, the pointed end was inlaid with glass, and the cylindrical end had several knobs.Wu Nanhai picked up the sugar meter and brought it close to his eyes, pointed the tip at the light, and adjusted the knob with his fingers.He turned to Lin Hanlong, "Old Lin, I'm sorry, I want to take a look."

Lin Hanlong nodded. "Of course."

Wu Nanhai turned his head. "Chuqing! Bring those bottles here."

The bottles are filled with clear water and sugar water mixed in different proportions.Wu Nanhai first dripped a few drops of water on the glass, and then turned the knob.Lin Hanlong handed over a piece of flannelette, Wu Nanhai took it and wiped off the water droplets, and then poured sugar water on it.He squinted his eyes and looked at the light for a while, then wiped off the sugar water, changed the bottle and added a few drops to make it look.After repeating this several times, he put down the sugar meter and exhaled.

"Old Lin, you are really good! This thing is very well made, and the sugar content measurement is very accurate." Wu Nanhai was already smiling at this time. "Very good, very good. I want as much of this thing as I want. I'll have someone report it later."

Lin Hanlong nodded. "You just sign the form, and you can stamp it with the seal of the Council of Agriculture later. This sample can be taken away now." He took out a wooden box from the drawer, opened it and handed it to Wu Nanhai, "the matching box .”

"The lenses here are mass-produced, no problem. But the prisms are hand-ground. Mass production has to wait for the surface grinder to come out."

"Oh, how long will it take? I plan to send out a batch before the next harvest season, and teach them how to use them in advance."

"It's up to the Navy. They need binoculars urgently. They say they plan to have two on each ship."

"That's a lot! Sucrose is an important source of income for us, so we can't lose it." Wu Nanhai said urgently.He was also pressed by Wen Tong—Wen Tong promoted the combination of sugarcane production in Leizhou, cultivated improved varieties, and the price according to quality is a major link in Leizhou's sugar industry policy. Without a sugar meter, the rules and regulations formulated by Wen Tong Unable to carry it out.

"Who says it's not?" Lin Hanlong echoed casually, but didn't express anything concretely.
Wu Nanhai came to his senses: "Let me help you tell the executive committee that optical instruments are too important, and we need to increase investment."

"With you, one is worth three."

"Hahahahahahahahaha..." Wu Nanhai laughed a few times and raised his finger. Chu Qing quickly opened a straw woven bag and took out a wooden box from it.

"This is a freshly made cigar from the farm. Try it."

"No, no, I haven't finished the limited edition you gave me last time..." Lin Hanlong became polite.

"Try something new. This time it's Li Quan's limited edition." Wu Nanhai smiled, "Try it, I entrust the Jesuits to get the tobacco leaves from Macau, and the wrappers are made from the real Caribbean."

Lin Hanlong thought for a long time before he remembered who Li Quan was. He smiled and took the box.The box is made of a kind of precious wood, exuding a faint woody fragrance.According to Wu Nanhai, the wood was also imported from Southeast Asia.Black lettering was branded on the polished white germwood lid—even cursive script he didn't recognize.There is also a green label with the words "tax-free" from the Monopoly Bureau of the Ministry of Finance Superintendent on the box.It looks very stylish.

In contrast, the last limited edition was nothing more than a cardboard package.It doesn't matter which one is more advanced.Lin Hanlong found out that the package description of Li Quan's limited edition was "three incomes", and he couldn't help but secretly scolded Wu Nanhai for becoming a profiteer.

"Not bad." He also said haha.Wu Nanhai took out two more glass bottles from his pocket.

"This is fruit wine made from blueberries that Xue Ziliang grew at my place. The alcohol content is not high. You can drink it as a drink—it's hot enough here."

"How embarrassing, you always bring things..." Lin Hanlong felt a little embarrassed. In recent months, Wu Nanhai has been sending over sporadic things.

"It doesn't matter, you are busy with work here, and you still work night shifts every day, so you need to supplement your nutrition." Wu Nanhai disagrees, "The farm is just for the elders."

As Wu Nanhai said, he swayed and walked out, still holding the sugar meter box in his hand.The naturalized people under his command filed out after him.When he was about to walk out of the workshop, he saw something out of the corner of his eye.He turned his head to look at it, let out an ah, and then jumped out to a corner of the workshop.

"Old Lin!!!!"

Lin Hanlong rushed out, and was meeting Wu Nanhai's faint green eyes, he couldn't help saying inwardly, "It's broken!"

Fatty Wu tremblingly pointed at a row of curved cast iron workpieces, and said in a trembling voice: "Xiao, Xian, microscope...you, why didn't you tell me." , which is no different from that used in later generations.

Lin Hanlong smiled wryly, "You didn't ask me if I could do it. These are ordered by the Ministry of Health, and they are urgently needed."

Fatty Wu jumped up immediately. "I didn't ask because I thought this stuff was difficult to make! Didn't it mean that it could only be mass-produced in the 19th century?"

"I used Leeuwenhoek's method, using surface tension to make aspheric lenses, and it's quite easy to make." Lin Hanlong pretended to be plain, "Of course, with a slight improvement, it can produce products of multiple specifications, and the accuracy Within one percent."

Wu Nanhai stared at Lin Hanlong for a while, then he laughed. "Old Lin! In terms of optics, you belong to us for more than 500 miles! You can do what others can't!"

"That's not true, and—"

Wu Nanhai patted Lin Hanlong's shoulder heavily:
"Old Lin! You have contributed a lot to the work of our Ministry of Agriculture! I, Wu Nanhai, understand it very well!" Fatty Wu patted his chest fluffily, "Don't talk nonsense, in the future, the Ministry of Agriculture will strongly support the work of the optical factory .Such an important matter should be put in a priority position for development. Executive Committee, I will take care of it!"

The two laughed again for a while.

Wu Nanhai suddenly remembered something. "Old Lin, according to your habit, you must have made a few test products before mass production, right?" When he said this, the green light in his eyes was enough to illuminate the entire workshop.

Apart from being a bit rough, the self-made microscope that Lin Hanlong took out looked no different from the products of later generations at a glance.He pointed to the objective lens and said: "Three magnifications, 50, 150, and 300. However, the positioning mechanism is not very good. Be careful when turning it, and adjust it a little to prevent the optical path from being incorrect." Pointing to the eyepiece: " The eyepiece is not painted, wipe it clean after use, otherwise sweat will corrode."

Lin Hanlong found a piece of cloth to wrap the microscope: "I didn't make a box, so you can just take it with you. This is a trial product, and there are still many minor flaws. You should be careful when using it, and tell me if you have any problems."

"It's easy to say! It's easy to say!" Wu Nanhai walked out contentedly, holding the sugar meter in his left hand and the microscope in his right hand.

After sending away Wu Nanhai, who looked like a devil leaving the village, Lin Hanlong asked his apprentice to get another towel to wipe his face, and hurriedly started his second inspection of the workshop.The professional level of the workers is not high, even if they are experienced, they are in a state of half understanding.Half a bottle of vinegar is the most dangerous, and bad things happen from time to time, and it's hard to guard against.

When Lin Hanlong patrolled the grinding machine halfway and was listening carefully to the sound of the machine, someone came to report that there was a Chief Qian at the door looking for him.

This Chief Qian has a strong body, with obvious muscular lines.He was wearing a T-shirt, shorts, and sunglasses in the standard attire of a veteran, with a pistol holster tied on his thigh, revealing a square-headed gun handle.Although it is standard attire, but upon closer inspection, this attire is quite different from others.The sunglasses are like that of Tom Cruise in Top Gun, and the solid-colored T-shirt with a collar can actually give you a stylish look. The shorts are obviously military products such as 511, and even the shoes are not ordinary running shoes that can be seen on the market.

The visitor took off his sunglasses, revealing a pair of piercing eyes.It is the current speaker and house party leader Qian Shuiting
"Old Qian! What brought you here?" Lin Hanlong greeted him with a haha.

"I just went to the machinery factory for research today. I'll come over to see you when I'm done. How's it going? Have you eaten yet?"

Lin Hanlong shook his head. "I don't have time. Let the cafeteria send something over later."

Qian Shuiting took out a large box from the straw pocket behind him: "I have prepared some things here, why don't we eat together?"

Inside the box were two large lunch boxes preserved with ice cubes. Lin Hanlong glanced into the box. "Sushi! Where did you get it?"

The rice balls in the box are rolled up with laver and covered with red and white fish.It is the Japanese sushi that is well-known in later generations.

Lin Hanlong invited Qian Shuiting into the office.There were so many things on the desk that it was difficult to clean up, so someone set up a small foldable table and wiped it to make it a dining table.The two sat opposite each other.Lin Hanlong asked his apprentice to bring a few bottles of kvass—it was inconvenient to drink seriously during working hours.

Qian Shuiting said that when he was working in California, he also worked in a Japanese restaurant, making sushi or something.It's a pity that there is no suitable sushi rice in the local area, and the taste can only be used.Of course, there is no sushi vinegar, but Tianchu has brewed white vinegar, which can be used as a substitute for the time being.The Feiyun can often go out to sea for fishing, and has made an appointment with some fishermen to deliver the good goods as soon as possible, so the seafood and fish are still fresh.
"Tianchu has Japanese soy sauce: after all, everyone often eats sashimi." Qian Shuiting said as he opened a lunch box, "This is fresh mustard from Wu Nanhai - I grind it myself, it's not wasabi paste .”

"Speaking of Wu Nanhai, he just left my place." Lin Hanlong always adhered to the view that being happy alone is worse than being happy with others, and picked up Li Quan's limited edition cigar from the table, "How about it, one later?"

"No, you should smoke it yourself." Qian Shuiting said, "Now I have to strictly demand myself."

At first Lin Hanlong thought that Qian Shuiting meant caring for his body, but later he realized: "You mean you can't take other people's gifts?"

"That's what it means."

"It's just a box of cigars..." Lin Hanlong didn't take it seriously. Almost all the elders had a share in this kind of private gift to stimulate affection.

Qian Shuiting shook his head: "We don't lack these circulation coupons, it's better to buy them directly, so as not to be a stain on the scene. The old Wu people are very good, and they can't stand someone—" He probably felt that this was inappropriate. said.

"Do you think this is the country of America..." Lin Hanlong felt that since Lao Qian organized the house party and became the speaker, he behaved very differently from before—a bit too neurotic, and politics is really not something ordinary people do.

"It's not the country of the United States, so you have to pay attention. It would be easier to deal with it in the country of the United States." Qian Shuiting said and poured him a glass of kvass, "Come on, have a drink first."

After a few pieces of sushi went down, Qian Shuiting stared at Lin Hanlong: "Old Lin, I didn't blame you. You're a little thinner than last month."

"Eh? I don't think so." Lin Hanlong has a lot of appetite, the weather is hot, eating cold food like sushi is just right for him.

Qian Shuiting picked up his chopsticks and nodded: "You are turning black and white. You work all night at night, have meetings in the morning during the day, and do things at the machinery factory. It's the hottest time at noon, how can you sleep well? ?" He picked up a piece of sushi and put it in Lin Hanlong's bowl, "This is flying fish roe, it's very good. You eat more. You can't sleep well, eat well, and you're tired. Can you not lose weight? Your body is still Do you want it?"

"In the early stages of a career, hard work is always inevitable."

"Everyone is starting their careers, and you have worked much harder than others."

"When the autumn optics factory has an independent power source, it won't have to work the night shift. It will be easier then."

"Just talking about this matter. The steam engines of the machinery factory are sent out one by one. Why is your optics factory so close to the water, but you have to wait until autumn?"

This is hitting Lin Hanlong's sore spot.

"You also know that some people in the executive committee said that it would not be too late to wait for the development of optics in the second five or three fifths. What do you think?"

Lin Hanlong shook his head: "What do they know? I have so many people urging for this and that, but I can't do it."

"That's right! They only understand one acre of land, who knows better? It's only been a few years, and I don't listen to what the senior veterans have to say."

"No one in the executive committee has ever engaged in scientific research, not even a graduate student. There is no intuitive experience in scientific research and development."

"If things go on like this, how to climb the technology tree will be decided by them? Isn't this a layman leading an expert?"

Lin Hanlong waved his hand: "Forget it, let's eat." He was really hungry, and he quickly finished most of a large box of sushi.A bottle of kvass can also be drunk to the bottom.

Qian Shuiting watched Lin Hanlong put down the kvass bottle, and said, "I think there must be a voice to speak for the front-line technical veterans."

Lin Hanlong looked at Qian Shuiting, but didn't speak.

"Take your optical factory as an example. Many people think that we still have a lot of inventory, so there is no need to rush. From my point of view, no matter how much inventory you bring, the categories will always be incomplete, and the quantity will always be limited."

Lin Hanlong nodded in agreement. "People from all walks of life asked me for a lot of things, many of which I had never heard of before."

"Old Lin, you are so busy, and black and white are upside down, it is not easy to speak. I am the speaker, and speaking is my job. I think I have to speak for the vast number of technical veterans. "Qian Shuiting looked at Lin Hanlong sincerely.

"We understand the importance of your optics. But how far we can do it at this stage, can you tell me the truth?"

Lin Hanlong nodded again: "I'll trouble you if that's the case." He was silent for a while and organized his words.

"Optics, in terms of theory and design, our time and space is a very mature thing." He pointed to himself, "I came from an optical class, and I also do optical work. I can handle design and so on. Craft manufacturing is not particularly difficult. Many enthusiasts can grind lenses by themselves, and my professional class is at least not worse. To put it bluntly, optical things are mainly a kind of precision machining, nothing more than The amount of processing is relatively small, and there are relatively simple ways to make accurate measurements." He looked at Qian Shuiting and paused, "I dare say that as long as the resources are sufficient, I can keep doing it in a few years before the 20th century. Level."

Qian Shuiting was agitated. "Old Lin, you are so good here! It's great!"

Lin Hanlong nodded. "Seeing is believing. Last time you said you wanted to see me, are you free today? I'm going to make an inspection.
