Carefree Prince In Tang Dynasty

The microscope is a very precise optical instrument, and the lens is its soul. Of course, it needs to be polished by a skilled craftsman. If Datang has any kind of mirror grinding master whose profession is closest to later generations, it should be these craftsmen who have dealt with gems for many years, right?

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

After all, Wu Zhen is a reliable young man, and in half a day he found three masters, all carrying their own big bags. Not to mention how their actual technology is, just to say that their look gives people a sense of peace of mind.

And the final result also proved that these craftsmen who usually deal with gems toss up the glass, it is not too easy. After Li Xin calculated the size of the lenses he needed with his little optical knowledge, and gave it to these masters, they grind out a small pile of suitable lenses within five days.

Frankly speaking, even Li Xin didn't expect things to go so smoothly. He was overjoyed and rewarded each of the three craftsmen with a hundred pens. The three of them were so happy that their legs were weak, and they looked at each other and thanked each other. They also patted their chests and said that if the prince has any other needs in the future, just come to them.

Li felt confident, and simply proposed to keep the three of them as errands at the metallurgical base, and by the way, he also offered a lucrative monthly salary of two consistent dollars a month. The three of them were originally craftsmen. They all relied on their own hands for eating. The wind and rain were reduced by half. Now they have the opportunity to enter the system, and the treatment is so generous. Wherever there is a reason to refuse, they accepted it with a pretense of refusal.

With suitable lenses, the microscope is easy to handle.

The lens of an optical microscope is divided into two groups, one group of objective lenses and one group of eyepieces, which are essentially convex lenses. The light reflected by the object first forms an upside-down magnified real image through the objective lens, and then magnifies through the eyepiece and enters the human eye. After two magnifications, the image seen by the human eye can be dozens of times or even hundreds of times larger than the object itself.

The more magnification, the higher the quality requirements of the lens, that is, the higher the accuracy requirements. Li Xin felt that there was no need to blindly build such a high-power microscope, so he first assembled five microscopes with these lenses, with magnifications ranging from one hundred to three hundred, to see what the cells were. It was enough.

You know, when the first microscope capable of seeing cells appeared in later history, it was already at the end of the seventeenth century, which was a thousand years away from the present. From this perspective, it is not an exaggeration to say that Li Xin is enough to presuppose the development of Datang Biomedicine for a thousand years.

After all, in this field, equipment leadership is of utmost importance.

Li Xin looked at these simple microscopes, and couldn't help but dreamily: Maybe Sun Simiao could become the father of cytology through these microscopes? Schleiden, Schwann, and so on, let him climb... if it goes a little bit more smoothly, it seems that penicillin is not impossible, then the overall strength of my Datang is going to rise another step!

Thinking of these beautiful things, Li Xin couldn't help showing a smile that didn't seem very clever.

Shaking his head to drive away the excessively beautiful fantasies, his gaze regained his clarity again, and he immediately ordered the five microscopes to be sent to the Faculty of Medicine 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 notify Sun Simiao.
