Microscope model is one of the indispensable tools in scientific research and education. The basic principle is to magnify tiny objects, making details that cannot be directly observed by the naked eye visible. There are many types of microscopes, the most common of which are optical microscopy, electron microscopy and fluorescence microscopy.
An optical microscope uses visible light to pass through a sample and focus the light to form an enlarged image in the eyepiece. Its structure usually includes light source, objective lens, eyepiece and so on. The magnification of the objective is closely related to the design of the lens. Some high-performance objective lenses can provide up to hundreds or even thousands of times magnification, suitable for the observation of bacteria, cell structures and other small organisms.
Electron microscopy uses electron beams instead of visible light for imaging. The resolution of this microscope is much higher than that of the optical microscope, which can reach the nanometer level. Therefore, electron microscopy is often used in materials science, biology and other fields to help researchers observe structures and properties at the atomic level. Despite its high cost and complex operation, its precision and meticulousness make it an important place in the scientific community.
Fluorescence microscopy is a special type of light microscope that looks at cells and molecules through a fluorescently labeled sample. This kind of microscope can selectively excite fluorescent substances in the sample to produce fluorescence of specific wavelengths, so as to realize the visual study of biomolecules and cells. Fluorescence microscopy is widely used in cell biology and medical research, helping scientists gain insight into disease mechanisms and cell behavior. Regardless of the microscope model, they open new horizons for scientific exploration.

A microscope is an instrument that uses optical principles to magnify tiny objects, allowing us to see details that the naked eye cannot recognize. Its basic structure includes a light source, an objective lens, an eyepiece and a stage. The light source provides illumination, the light is focused on the sample through the objective lens, and the eyepiece further magnifies the object, allowing the observer to clearly see the fine structure.

There are many types of microscopes, including optical microscopes, electron microscopes, and scanning tunneling microscopes. Optical microscopes use visible light for imaging and are suitable for viewing living cells and tissue slices, and their imaging principles are based on refraction and reflection. Through different magnification objectives, the observer can obtain different magnification effects, so as to study the structure and characteristics of the sample.

Electron microscopy, which uses electron beams instead of visible light, has a higher resolution and is able to see details at the nanometer level. This kind of microscope is particularly suitable for research in the fields of materials science and biology, and can reveal the ultrastructure of the inside of cells. For example, transmission electron microscopy can observe the internal structure of a sample, while scanning electron microscopy provides rich data for scientific research by obtaining three-dimensional morphological information on the surface of a sample.

The application field of microscope is very wide, not only limited to biology, medicine, but also includes materials science, nanotechnology, chemistry and other disciplines. Through microscopes, researchers can explore the mysteries of the microscopic world, discover the properties of new materials, study the functional changes of cells, and even observe pathological slides in medical diagnosis to help doctors better judge diseases.

A microscope is an optical instrument that magnifies tiny objects and is widely used in scientific research and education. Its basic principle is to use the refraction and reflection of light to magnify the sample through multiple lens systems, so that the human eye can observe the microscopic structures that cannot be directly seen under normal circumstances.

In the design of a microscope, several different types of lenses are usually included. The most important thing is the objective and the eyepiece. The objective lens captures and magnifies the light in the sample, while the eyepiece further magnifies the image created by the objective lens. With the synergistic action of these two lenses, the microscope can achieve high magnification and clear imaging effects.

Modern microscopes can be roughly divided into two categories: optical microscopy and electron microscopy. Optical microscopes use visible light for imaging and are suitable for observing biological samples such as cells and tissue slices. It has the advantage of simple operation and relatively low cost, but its resolution is limited by the wavelength of light. In general, the maximum resolution of an optical microscope is about 200 nanometers.

In contrast, electron microscopes, which use electron beams for imaging, are able to achieve much higher resolution and are often able to observe structures at the nanoscale. This makes it widely used in the fields of materials science, nanotechnology and biomedicine. However, the operation of electron microscopy is relatively complex, the sample preparation process is also more complicated, and the use cost is high.

The invisibility microscope is a new technology, which can observe the internal structure of the sample without damage, and has important application potential. This technique relies on special imaging principles, such as fluorescence, phase contrast, and confocal methods, allowing researchers to observe dynamic processes in living samples.
