Carefree Prince In Tang Dynasty

A microscope is a very precise optical instrument, and the lens is its soul. Of course, it needs a skilled craftsman to polish it. If there is any occupation in Datang that is closest to the mirror grinders of later generations, it should be these craftsmen who have been working with gems for many years, right?

Although there is a difference in value, there should be no essential difference between polished gemstones and polished glass.

After all, Wu Zhen was a reliable young man, so he found three masters within half a day, each carrying his own bags. Not to mention how their actual skills are, just saying that their appearance looks quite reassuring.

And the final result also proves that it is not easy for these craftsmen who usually deal with gemstones to toss glass. After Li Xin calculated the size of the required lenses with his little optical knowledge and handed them over to these masters, they ground out a small pile of suitable lenses within five days.

Frankly speaking, even Li Xin didn't expect things to go so smoothly, and overjoyed, he generously rewarded each of the three craftsmen with a hundred guan. The three of them were so happy that their legs were weak, they looked at each other, thanked each other, and patted their chests to say that if the prince needs anything else in the future, just come to them.

With a wave of confidence, Li simply suggested that the three of them should stay in the metallurgical base as errands, and by the way, he offered a generous monthly salary of two yuan a month. The three of them were originally craftsmen, and they had to rely on their own hands to eat, and the wind and rain were halved. Now that they have the opportunity to enter the system, the treatment is so generous, there is no reason to refuse, and they accepted it with a false refusal.

With the appropriate lens, the microscope is easy to handle.

The lenses of an optical microscope are divided into two groups, a group of objective lenses and a group of eyepieces, which are essentially convex lenses. The light reflected by the object first passes through the objective lens to form an inverted magnified real image, then magnifies through the eyepiece and enters the human eye. After two times of magnification, the image seen by the human eye can be dozens or even hundreds of times larger than the object itself.

The higher the magnification, the higher the quality requirements for the lens, that is, the higher the precision requirements. Li Xin felt that there was no need to blindly build such a high-power microscope, so he used these lenses to assemble five microscopes. The magnification was between 100 and 300, which was enough for looking at cells.

You must know that it was the end of the seventeenth century when the first microscope capable of seeing cells appeared in the history of later generations, which is a thousand years behind now. From this perspective, it is not an exaggeration to say that Li Xin fully premised the development of Datang Biomedicine for a thousand years.

After all, in this field, the leading equipment is very important.

Looking at these simple microscopes, Li Xin couldn't help but fantasize: Maybe Sun Simiao could use these microscopes to become the father of cytology? Schleiden, Schwann, etc., let's climb for the master. If it goes well, it seems that it is not impossible to discover penicillin, then my overall strength of Datang may rise to another level!

Thinking of these beautiful things, Li Xin couldn't help showing a not-so-smart smile.

Shaking his head to drive away the overly beautiful illusions, his eyes became clear again, and he immediately ordered the five microscopes to be sent to the Medical College of the Ministry of Science. Xu Jingchen, who had moved the research site to the medical school a long time ago, saw these instruments and quickly sent someone to inform Sun Simiao.
