In what fields are optical microscopes mainly used?
Optical microscope is an ancient and young scientific tool. It has a history of three hundred years since its birth. Optical microscope is widely used, such as in biology, chemistry, physics, astronomy, etc. in some scientific research work. All are inseparable from the microscope.
At present, it has almost become the image endorsement of science and technology. You only need to look at its frequent appearance in media reports on science and technology to see that this statement is true.
In biology, laboratories are inseparable from this kind of experimental equipment, which can help learners study the unknown world and understand the world.
Hospitals are the largest application places for microscopes. They are mainly used to examine changes in patients' body fluids, germs that invade the human body, changes in cell tissue structure, etc., and provide doctors with reference and verification methods for formulating treatment plans. In genetic engineering, microscopy In surgery, the microscope is the most important tool for doctors; in agriculture, breeding, pest control and other tasks are inseparable from the help of the microscope; in industrial production, the processing, inspection and assembly adjustment of fine parts, and the study of material properties are what the microscope can display. Where is the skill? Criminal investigators often rely on microscopes to analyze various microscopic traces of crimes as an important means to determine the real culprits; environmental protection departments also rely on microscopes when detecting various solid pollutants; geological and mining engineers and cultural relics and archaeologists use microscopes The clues discovered can determine the mineral deposits buried deep underground or infer the historical truth; even people's daily life is inseparable from microscopes, such as the beauty and hairdressing industry, which can use microscopes to detect skin, hair quality, etc. Get the best results. It can be seen how closely the microscope is integrated with people's production and life.
Microscopes can be roughly classified according to different application purposes. The four common categories are biological microscopes, metallographic microscopes, stereo microscopes, and polarizing microscopes. As the name suggests, biological microscopes are mainly used in biomedicine, and the objects of observation are mostly transparent or translucent microscopic objects; metallographic microscopes are mainly used to observe the surfaces of opaque objects, such as the metallographic structure and surface defects of materials; stereomicroscopes are used to observe microscopic objects. While the object is magnified and imaged, the orientation of the object and the image relative to the human eye is consistent, and there is a sense of depth, which is in line with people's regular visual habits; polarizing microscopes use the transmission or reflection characteristics of polarized light of different materials to distinguish different micro-objects Component. In addition, some special types can also be subdivided, such as an inverted biological microscope or a culture microscope, which is a biological microscope mainly used to observe culture through the bottom of a culture vessel; a fluorescence microscope uses certain substances to absorb specific shorter wavelength light. The characteristics of emitting specific longer wavelength light to discover the existence of these substances and determine their content; a comparison microscope can form juxtaposed or overlapping images of two objects in the same field of view to compare the similarities and differences between the two objects.
