Introduction of main application fields of optical microscope
Optical microscope is an ancient and young scientific tool. Since its birth, it has been used for 300 years. For example, in biology, chemistry, physics, astronomy and so on, it is inseparable from the microscope in some scientific research work.
At present, it has almost become the image endorsement of science and technology. You only need to look at its frequent appearance in the reports on science and technology in the media to see that this statement is true.
In biology, the laboratory is inseparable from this experimental instrument, which can help learners to study the unknown world; To know the world.
Hospital is a large application place of microscope zui, which is mainly used to check the changes of patients' body fluids, bacteria invading human body, changes of cell structure and so on, and provide doctors with reference and verification means for making treatment plans. In genetic engineering and microsurgery, microscope is a tool for doctors. In agriculture, breeding, pest control and other work can not be separated from the help of microscope; In industrial production, the processing, inspection and assembly adjustment of fine parts and the study of material properties are the places where microscopes can show their talents; Criminal investigators often rely on microscopes to analyze various microscopic traces of crimes as an important means to determine the real murderer; The environmental protection department also needs to help the microscope when detecting various solid pollutants; Geological and mineral engineers and cultural relics archaeologists can judge the buried mineral deposits or infer the dusty historical truth with the help of the clues discovered by the microscope; Even people's daily life is inseparable from the microscope, such as the beauty salon industry, which can be used to detect the skin and hair quality, and it will achieve good results. Visible microscope and people's production and life is how closely.
According to different application purposes, microscopes can be roughly classified into four categories: biological microscope, metallographic microscope, stereoscopic microscope and polarizing microscope. As the name implies, biomicroscopes are mainly used in biomedicine, and the observation objects are mostly transparent or translucent micro-bodies; Metallographic microscope is mainly used to observe the surface of opaque objects, such as the metallographic structure and surface defects of materials; Stereo microscope enlarges and images micro-objects, at the same time, it also makes the orientation of objects and images consistent with human eyes, and has a sense of depth, which conforms to people's conventional visual habits; Polarizing microscope uses the transmission or reflection characteristics of different materials to distinguish different micro-components. In addition, it can be subdivided into some special types, such as inverted biological microscope or culture microscope, which is mainly used to observe culture through the bottom of culture vessels; Fluorescence microscope uses the characteristics that some substances absorb light with a specific shorter wavelength and emit light with a specific longer wavelength to find the existence of these substances and judge their content. A comparative microscope can form a parallel or overlapping image of two objects in the same field of view, so as to compare the similarities and differences between the two objects.
