(Summary description)Microscopes can magnify tiny objects that can't be seen by human flesh eyes through microscopes, which can expand the vision of human beings and promote the discovery and research of unknown things. Microscopes can be classified into optical microscope and electron microscope. There are many classifications under them. The polarizing microscope we are talking about today belongs to optical microscope. The differences between it and ordinary microscope are summarized in the following sections.
1. The ordinary microscope can observe the image according to the different transmittance of the sample. The principle of polarizing microscope is to use diffraction to observe the structure of the product more precisely.
2. The stage of ordinary microscope can't be rotated, but the stage of polarizing microscope can be rotated. Compared with ordinary microscope, it has a group of polarizing and checking bias. It can change ordinary light into polarized light, so as to identify whether the object is single refraction or birefringence. All birefringent objects must be observed by polarizing microscope, and the base of general crystal must be observed This characteristic is birefringence, so polarizing microscope is widely used in glass, semiconductor, mineral and other fields.
3. The detection method of polarizing microscope is not possessed by ordinary microscope, but also has the skills of ordinary microscope. However, the ordinary microscope with polarizing microscope does not support it. Therefore, the application scope of polarizing microscope is relatively wide, and the operation requirements are relatively high. Of course, the price is higher than that of ordinary microscope.
Polarizing microscope can be said to be the greatest invention of mankind in this period. It is the symbol of mankind entering the atomic age and has made great contributions to the research in various fields and the discovery of new species.
