Microscope Parts Widely Used In Biology, Medicine, Agriculture And Forestry

With the development of mankind, the type of Microscope Parts is more and more, the scope of observation is more and more widely, we have an understanding of the classification of optical microscopy.

First, according to the use of eyepiece number can be divided into monocular, binocular and trinocular Microscope Parts

Monopolistic price is relatively cheap, can be used as a beginner lovers choice, eyes slightly

First, according to the use of eyepiece number can be divided into monocular, binocular and trinocular Microscope Parts

Monopolistic price is cheaper, can be used as a beginner lovers of choice, eyes slightly expensive, when the observation of the eyes can be observed at the same time, the observation was more comfortable, three more eyes, its role is to connect a digital camera or Computer, more suitable for long hours of work selection.

Second, according to its use and application range is divided into biological Microscope Parts, metallographic Microscope Parts, stereoMicroscope Parts, etc.

1, biological Microscope Parts is the most common kind of Microscope Parts, can be seen in many laboratories, mainly used to observe the biological slices, biological cells, bacteria and living tissue culture, fluid precipitation observation and research, and can be observed Other transparent or translucent objects as well as powder, fine particles and other objects. Biological Microscope Parts for medical and health units, institutions of higher learning, research institutes for micro-organisms, cells, bacteria, tissue culture, suspension, sediment and other observations can be continuous observation of cells, bacteria and other culture in the culture of the process of division. In the cytology, parasitology, oncology, immunology, genetic engineering, industrial microbiology, botany and other fields widely used.

2, stereoscopic Microscope Parts, also known as solid Microscope Parts, stereoscopic Microscope Parts, is a kind of as a three-dimensional visual equipment, widely used in biology, medicine, agriculture and forestry. It has two complete optical path, so the observation of the object appears three-dimensional. The main uses are: ① as zoology, botany, entomology, histology, archeology and other research and anatomical tools. ② to do the textile industry in raw materials and cotton fabric inspection. ③ in the electronics industry, such as crystal assembly tools. ④ the various types of material stomatal corrosion and other surface phenomena of the inspection. ⑤ true and false judgment on paper money. ⑥ the quality of the lens, prism or other transparent material surface quality, and precision scale quality inspection.

3, metallographic Microscope Parts is mainly used to identify and analyze the internal structure of metal, metal research is an important instrument, is the industrial sector to identify product quality key equipment, specifically for the observation of metal and minerals and other opaque objects Metallographic organization Of the Microscope Parts. These opaque objects can not be observed in ordinary transmission light microscopy, so the main difference between metallographic and ordinary microscopy is that the former is reflected and the latter illuminates with transmitted light. Not only can identify and analyze a variety of metal, alloy materials, non-metallic material structure and integrated circuits, micro-particles, wire, fiber, surface coating and other surface conditions, metallographic Microscope Parts can also be widely used in electronics, The instrumentation industry observes opaque substances and transparent substances. Such as metal, ceramic, integrated circuit, electronic chip, printed circuit board, liquid crystal plate, film, powder, toner, wire, fiber, coating and other non-metallic materials in the metallographic Microscope Parts, Observe the surface of the object, reflected by the object and then return to the objective lens imaging. So the use of metallographic Microscope Parts to test the internal structure of the metal in the industrial production is very important. The stereoMicroscope Parts can also be used in industrial production, but it is only used to observe the metal surface scratches, scratches, etc., magnification is generally between 10X-50X, metallographic magnification is generally in the 50X-800X, some can Reaching 2000X.

Third, according to the optical principle can be divided into polarized, phase contrast and differential interference contrast Microscope Parts

1, polarized light microscopy is a microscopic identification of the optical properties of the fine structure of the Microscope Parts. Where the birefringence of the material, in the polarized Microscope Parts can distinguish clearly, of course, these substances can also be used to observe the dyeing method, but some are not possible, and must use polarizing Microscope Parts. Mainly used to study transparent and opaque anisotropic materials. A substance with birefringence can be observed with this Microscope Parts. Birefringence is the basic characteristic of the crystal. Therefore, polarizing Microscope Partss are widely used in mineral, chemical and other fields, such as in botany, such as identification of fibers, chromosomes, spindle filaments, starch granules, cell walls and cytoplasmic and tissue containing crystals. In the plant pathology, the invasion of bacteria, often caused by chemical changes in the organization, can be polarized microscopy to identify. In the human body and zoology, often use polarized light microscopy to identify bone skull, teeth, cholesterol, nerve fibers, tumor cells, striated muscle and hair.

2, phase contrast Microscope Parts, also known as phase contrast Microscope Parts, the biggest feature is that you can observe the stained specimens and live cells. These samples are not observed under the general Microscope Parts, and phase contrast Microscope Parts is the use of objects between the different components of the refractive index and thickness difference between the different parts of the object through the optical path difference into the amplitude difference, with a ring The aperture of the condenser and the phase difference with the phase of the lens to achieve the observation, it is simple to say that it uses the difference between the sample density to observe the difference, so even if the sample is not stained can also be carried out, which greatly facilitates the living cells Of the observation, so phase contrast method is widely used in inverted Microscope Parts. There is a phase plate of the objective lens called "phase contrast objective", the shell often "Ph" words. Phase contrast method is an optical information processing method, and is one of the earliest information processing results, so in the history of optical development is of great significance.

3, differential interference contrast microscopic examination appeared in the 1960s, it can not only observe the colorless and transparent objects, and the image showing a strong three-dimensional sense of relief, and phase contrast examination can not achieve some of the advantages of observation More realistic.
