What are the main categories of optical microscopes?
Optical microscopes are mainly binocular stereo microscopes, metallurgical microscopes, UV fluorescence microscopes, TV microscopes and charge-coupled device microscopes, scanning microscopes. Separate uses are:
1, binocular stereo microscope in biology, medical field widely used in section operation and microsurgery; in industry for tiny parts and integrated circuits observation, assembly, inspection and other work.
2,Metallographic microscope is specially used to observe the metallographic organisation of opaque objects such as metals and minerals. These opaque objects can not be observed in the ordinary transmitted light microscope, so the main difference between metallographic and ordinary microscope is that the former to reflect light, and the latter to transmitted light illumination.
3, ultraviolet fluorescence microscope for biological and medical fields. Some specimens in the visible light can not be perceived in the structural details, but after staining, to the ultraviolet light irradiation can be due to the role of fluorescence and emission of visible light, the formation of visible images. This type of microscope is commonly used in biology and medicine.
4, TV microscope and charge-coupled device microscope can be linked with a computer, which facilitates the automation of detection and information processing, more often used in the need to carry out a large number of cumbersome detection of the occasion.
What is the role of microscope in medicine
Optical microscope is commonly used in the field of medical and health care testing equipment, in China almost all hospitals, epidemic prevention stations, health clinics and medical colleges and universities are inseparable from the optical microscope. Optical microscopes can be used by medical and health units for the observation of microorganisms, cells, bacteria, tissue cultures, suspensions, precipitates, etc. They play a great role in maintaining the health of the general public and in the examination of diseases.
