Where are the main applications of optical microscopes?
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, and other information. They provide doctors with reference and verification methods for formulating treatment plans. In genetic engineering, visualization In microsurgery, 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 all possible with the microscope. Where to show your skills; 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 by the microscope can determine the mineral deposits buried deep in the ground or infer the dust-covered 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.
Over the years, people have worked hard to improve the resolving power and imaging contrast of microscopes. With the continuous advancement of computer technology and tools, the theory and methods of optical design are also constantly improving. In addition, the performance of raw materials has improved, and the process and The continuous improvement of detection methods and the innovation of observation methods have made the imaging quality of optical microscopes close to the perfection of the diffraction limit. People will use observation techniques such as specimen dyeing, dark field, phase contrast, fluorescence, interference, and polarization to make optical microscopes have It can be adapted to the research of all kinds of specimens. Although magnifying imaging instruments such as electron microscopes and ultrasonic microscopes have come out in recent years and have superior performance in some aspects, they are still not cheap, convenient, intuitive, and especially suitable for the study of living organisms. Rivaled by light microscopy, light microscopy still holds its own firmly. On the other hand, combined with lasers, computers, new material technology, and information technology, ancient optical microscopes are rejuvenating and showing strong vitality. Digital microscopes, laser confocal scanning microscopes, near-field scanning microscopes, two-photon microscopes and Instruments with various new functions or that can adapt to various new environmental conditions emerge in endlessly, which further expands the application fields of optical microscopes, as an example. How exciting are the microscopic pictures of rock formations returned from the Mars Exploration Rover! We can fully believe that optical microscopes will benefit mankind in a new way.
