What are the contents of microscope classification

Microscopes can be classified based on the principle of microscopy, including polarized light microscopy, optical microscopy, electron microscopy, digital microscopy, etc.
Polarizing microscope
Polarizing microscope is a type of microscope used to study so-called transparent and opaque anisotropic materials, and has important applications in science and engineering majors such as geology. Any substance with birefringence can be clearly distinguished under a polarizing microscope. Of course, these substances can also be observed using staining methods, but some are not, and must be observed using a polarizing microscope. Reflective polarization microscope is an essential instrument for studying and identifying substances with birefringence by utilizing the polarization characteristics of light. It can be used by users for single polarization observation, orthogonal polarization observation, and cone light observation.
optical microscope
Usually composed of optical parts, lighting parts, and mechanical parts. Undoubtedly, the optical part is the most crucial, consisting of an eyepiece and an objective lens. As early as 1590, eyewear manufacturers in the Netherlands and Italy had already created magnifying instruments similar to microscopes. There are many types of optical microscopes, mainly including bright field microscopes (ordinary optical microscopes), dark field microscopes, fluorescence microscopes, phase contrast microscopes, laser scanning confocal microscopes, polarizing microscopes, differential interference differential microscopes, and inverted microscopes.
electron microscope
Electron microscopes have basic structural features similar to optical microscopes, but they have much higher magnification and resolution of objects than optical microscopes. They use electron flow as a new light source to image objects. Since Ruska invented the first transmission electron microscope in 1938, in addition to continuously improving the performance of the transmission electron microscope itself, various other types of electron microscopes have also been developed. Such as scanning electron microscopy, analytical electron microscopy, ultra-high pressure electron microscopy, etc. By combining various electron microscopy sample preparation techniques, in-depth research can be conducted on the structure or structure function relationship of the samples from multiple aspects. Microscopes are used to observe images of small objects. Commonly used for observation in biology, medicine, and small particles. An electron microscope can magnify objects up to 2 million times.
Desktop microscopes mainly refer to traditional microscopes, which are purely optical magnifiers with high magnification and good imaging quality. However, they are generally large in size and difficult to move, and are often used in laboratories, making it inconvenient to go out or conduct on-site inspections.
Portable microscope
Portable microscopes are mainly an extension of the series of digital microscopes and video microscopes developed in recent years. Unlike traditional optical amplifiers, handheld microscopes are digital amplifiers that generally pursue portability, small and exquisite size, and easy portability; And some handheld microscopes have their own screens that can be used for independent imaging without the computer host, making them easy to operate. They can also integrate some digital functions, such as supporting photography, video recording, image comparison, measurement, and other functions.
The digital liquid crystal microscope was first developed and produced by Boyu Company. This microscope retains the clarity of optical microscopes, combines the powerful expansion of digital microscopes, the intuitive display of video microscopes, and the simplicity and convenience of portable microscopes.
