How metallographic and optical microscopes differ
Stereoscopic microscope is a microscope with two complete optical paths, which has a three-dimensional sense when observing specimens and has many uses. Stereoscopic microscope is a type of microscope with a three-dimensional sense. Stereoscopic microscopes can be equipped with microscopic digital imaging devices to become digital stereomicroscopes.
In this way, there is an advantage in observation:
1. It can reduce eye service and achieve multi person synchronized preview at low cost.
2. You can save the observed images and pass them on to each relevant section for viewing.
3. It can perform other functions such as recording and measuring. Stereoscopic microscopy is easy to operate, with a magnification generally between 7X-42X and a large magnification of 180X.
Stereoscopic microscopes are also widely used, with the following main applications:
1. Research in zoology, botany, entomology, histology, mineralogy, archaeology, geology, and dermatology.
2. It can be used for the inspection of raw materials and cotton wool fabrics in the textile industry.
In the electronic industry, it is used as a tool for transistor spot welding, inspection, and other operations.
4. Inspection of surface phenomena such as crack composition, pore shape, and corrosion of various materials.
5. The device used as a machine tool for manufacturing small precision parts, observation of the working process, inspection of precision parts, and assembly tools.
6. Surface quality inspection of lenses, prisms, or other transparent materials, as well as quality inspection of precision scales.
7. Distinguishing the authenticity of digital stereomicroscope essay books and banknotes.
8. Widely used in textile products, chemical engineering, plastic products, electronic manufacturing, mechanical manufacturing, pharmaceutical manufacturing, food processing, printing industry, higher education institutions, archaeological research and many other fields.
Because the virus is very small. The diameter of most individual virus particles is around 100nm, which means that arranging around 100000 virus particles can barely be seen with the naked eye.
The virus is so small that the vast majority of viruses can only be observed with the help of an electron microscope, which has a resolution 1000 times that of an optical microscope. There are significant differences in size between different viruses. The smallest Geminiviruses in plants have a diameter of only 18-20nm, the largest Poxviruses in animals have a size of 300-450nm x 170-260nm, and the longest viruses in the Filoviridae family have a particle size of 80nm x 790-14000nm.
