The key for mankind to open the microscopic world-microscope!

　　In our human eyes, the world is colorful, thanks to our human trichromatic vision. In nature, most animals only have bichromatic vision, and the world in their eyes is darker. Of course, there are also birds in nature that are stronger than human vision. In addition to our trichromatic vision, they also have visual cells that see ultraviolet rays, so the world in birds' eyes is more exciting than ours.

　　However, the treatment of details by animal eyes is extremely limited. For example, we humans can only see objects with a diameter of more than 0.1 mm, just like the needle of the embroidery needle used by grandma, no matter how small it is, we can't catch it with our naked eyes. However, this world is not only the world in our eyes, but the micro-world is actually more exciting.

　　In order to explore the microscopic world, as early as 1590, Dutch optician Yas Zhan Sen and his son invented the world's first microscope-optical microscope, which is simply a microscope that uses optical lenses to produce enlarged images.

　　Then, in the early 17th century, the microscope formally set foot in the field of science. Galileo saw the compound eye of insects with a microscope and made a scientific description. After that, the Dutchman Ravenhoek, inspired by the microscope, grinded his own lens and found tiny plants and animals that he had never seen before.

　　After discovering the wonders of the micro-world, the traditional microscope can no longer satisfy the scientists' further exploration of the micro-world. With continuous research, in 1926, Hans Bush finally developed the first magnetoelectric lens, which officially opened the prelude from the traditional microscope to the electron microscope.

　　Compared with the traditional microscope, the object that the electron microscope can observe is smaller, because the resolution of the traditional microscope is about 200 nanometers, while the resolution of the electron microscope can reach 0.2 nanometers.

　　However, the electron microscope is constantly upgrading, and the advent of transmission electron microscope (TEM) and scanning electron microscope (SEM) has also given us a deeper understanding of the deeper micro-world. For example, transmission electron microscope, as an advanced microscope, uses electron beams instead of light, which has higher resolution and greater magnification than optical microscope.

　　It can observe the nano-scale fine structure and atomic composition, and can see the crystal structure, surface morphology, atomic arrangement and chemical composition of materials, and can be used in the research of materials science, chemistry, biology, medicine and other fields. Therefore, the transmission electron microscope is widely used in materials science, biomedicine, energy, nanotechnology, semiconductor manufacturing and other fields, and it is a very powerful tool.

　　In fact, the invention of electron microscope also found a microorganism that may exist everywhere for human beings, but it will not be found by traditional microscopes. It is a virus, because the virus is much smaller than the smallest bacteria, and it cannot be observed by traditional microscopes. Under electron microscope, it has nowhere to hide. It is precisely because of this that before the appearance of electron microscope, the virus was just a concept, and it was considered by scientists to be a microorganism much smaller than bacteria. How small it was is is unknown.

　　It is precisely because we know little about viruses that people were helpless when viruses were rampant in the past. With the electron microscope, scientists can observe and study them and find a way to eliminate them. Therefore, the microscope is definitely a great invention that benefits all mankind.

　　Nowadays, microscopes are indispensable tools in schools, laboratories and research studios, and they have even entered thousands of households. I have seen some children in the park holding portable microscopes to observe samples of lake water, epidermal cells of plants, etc. This sense of accomplishment in exploring nature by themselves is obviously more exciting than playing a game of mobile phones and watching an cartoon.

　　However, with the increasing demand for optical measuring instruments such as microscopes, many people can't find some professional ways to buy them, and Mumu Xili Laboratory Mall has perfectly solved people's pain points. There are not only various experimental instruments, but also all kinds of application instruments. The key point is that Mumu Xili's solution hall has a complete laboratory turnkey solution, application solution and product customization solution, which can help customers solve various problems more accurately.

　　Therefore, it can be said that the microscope is not only the key to open the human micro-world, but also a stepping stone to the research in various scientific fields.

　　Make optical measurement easier.
