Although it has only been a short period of two months, the optical laboratory has initially reached the level of the domestic standard optical laboratory, even if it is not comparable to the hardware facilities of Mie Company, but it can still see the past, and no one underestimates it when the group comes to the laboratory.

Shu University is definitely the top university in China, and accordingly, it has to have a certain strength to hang the brand of Shu University Optical Laboratory.

"There is cooperation between you and the Shu University Laboratory, is it possible that your technology is provided by the laboratory here?"

The more high-end the product, the more clear the subdivision of the work, the aviation system is used in this mode, almost as a matter of course, the foreign affairs personnel in charge of translation also think that the same is true of the Shuhang Optics with the background of the Ministry of Aviation Industry.

If you really want to talk about it, glasses are simply assembled with translucent parts, the technical content is really not high, more rely on the accumulation of technology and experience, such as the sudden rise of Shuhang Optics, and will definitely be able to become an optical giant, in fact, there are very few.

The use of resin materials in the glasses industry, just like the internal combustion engine instead of the steam engine, has a strong influence enough to make the entire industry completely reshuffle.

In the early stage of the development of new materials, it is indeed necessary to overcome some technical problems, but once these problems are overcome, the follow-up technical problems are almost negligible.

"At present, we are indeed cooperating with the optical laboratory to overcome technical problems, but after the follow-up completion of relevant technical research, more glasses-related technical work will be handed over to Shuhang to solve by itself, and we and the optical laboratory have other projects to tackle. ”

........

The professor already knew about John's itinerary, so he took the time to come to the door of the laboratory to greet him.

Seeing John's standard British face, standing next to the professor and the vice president in charge of the scientific research work of Shu University is really happy from the bottom of my heart, I didn't expect this small optical laboratory to suddenly break out of an unpopularity, and it has a relationship with foreigners, so calculated, now Shu University is also in line with international standards, it seems that in the second half of the year, the school's hardware procurement can be appropriately tilted towards this optical laboratory.

As a reporter from a newspaper directly under the Ministry of Education in the Bashu region, he knows what it means for domestic universities to be able to communicate with foreign counterparts in scientific research, which can at least be regarded as a major news that the scientific research of colleges and universities has worked hard to integrate with international standards.

I just want to see what the specific situation of this exchange is, if the two sides can have further cooperation plans in the future, it will definitely be able to bring added value to this news, and it is not an exaggeration to use the front page to report the article.

The professor didn't have time to pay attention to the relevant people who came to hear the news, he knew what was the focus of this exchange and cooperation between the two sides, so he stepped forward and shook hands cordially.

"Hello Mr. John, I am the person in charge of the optical laboratory, you are very welcome to visit the laboratory, I believe that everyone will have something to gain in today's exchange, now follow me into the laboratory to visit, this time the relevant equipment and materials need to be prepared have been prepared, we can start at any time. ”

If you want to talk about academic exchanges, it is also a matter between schools and schools, and the scientific research community, John can only be regarded as an optical product engineer at best, maybe he has advanced engineering design concepts, but the current cutting-edge theoretical topics in the industry, maybe he is really not as rich as Professor Liu.

Therefore, the professor knows very well how this so-called exchange should be operated, especially when there are school leaders and newspaper reporters in the factory, it is better to talk less and do more experiments to be more convincing.

When it comes to his own interests, John is also an out-and-out actionist, and as soon as he heard that the relevant equipment and materials have been prepared, he naturally can't wait to start experiments, and strive to be able to exchange relevant technologies as soon as possible.

Everyone rushed into the laboratory, regardless of whether the laboratory was simple or not: "What you said is very reasonable, we will both gain something from this exchange, considering that we plan to exchange more projects today, I think it is best to start the experiment now, and the rest of the places will be exempted!"

walked into the dressing room on the side, changed into a new white coat that had been prepared a long time ago, and when he came out again, he was a typical image of a scientific and technological worker, and even his golden hair had been wrapped in a hood, unless he looked at John's facial features from the front, he really couldn't tell that this was a European and American person.

Seeing that the British experts who came to do technical exchanges had changed their clothes, the reporters who were waiting knew that this was the rhythm of making a move to show real skills, and only made such a move during the first exchange.

To say that this reporter is also a talent, when he was shooting, he also knew that he was half-squatting from John's back forty-five degrees upward, and suddenly highlighted the height of his back, why didn't he find that his photography skills were so good before, it was really strange.....

"I have done some research on the PMMA material you use before, it does have the problem of yellowing of the lens material after long-term use, in fact, the previous generation of PMMA material of our Sanzhong company also had this problem, and then through the control of the production environment of the material molding process, mainly to increase the dust-free control requirements in the production process, and then by adding a new coating, so as to effectively solve the problem of yellowing of the material. ”

On the one hand, in the old production environment, the conditions on the site are limited, and there will be many invisible impurities mixed into the PMMA material in the molten state, and the final product will naturally have a low performance in terms of light transmittance.

In addition, what really makes the lens yellow is not actually the defect of the material itself, in fact, PMMA material is not something that can be used for a long time like silicate glass, and it is normal for the material to change color under the intense sunlight for a long time.

He went on to explain: "The yellowing of PMMA material is an inherent defect that cannot be solved, it is like wrinkles when people get old, and we can't avoid it. The only thing that can be done is to delay the yellowing, that is, to delay the aging process, which is the same as the maintenance of people's skin. ”

Holding the chalk in his hand, he wrote various technical key points on the blackboard: "In order to delay the aging of materials, we found that the direct exposure of sunlight is one of the reasons for accelerating the aging of materials, which is actually similar to the causes of human skin aging. ”

This is really a new idea, when the laboratory analyzed the causes of lens yellowing, I never thought that there would be such a solution to the problem, sunscreen, hydration?
