The microscope is one of the most commonly used optical instruments in the laboratory. With the advancement of technology, more and more microscopes are developed and can observe a wider range of objects. These different categories of microscopes are used in different research and applications.
According to the different microscope observation images, the microscope is divided into the biological microscope, metallurgical microscope, and stereomicroscope. The biological microscope is mainly used to observe biological slices, biological cells, bacteria, living tissue culture, fluid precipitation, and other research, and can be used to observe other objects such as powders, fine particles, and transparent or semi-transparent objects. A stereo microscope is a kind of visual instrument with a positive image stereoscopic sense. With its two complete optical paths, it presents a three-dimensional view of the object when observed. In the biology laboratory, a stereomicroscope is an important tool for the study and dissection of zoology, botany, entomology, histology, archaeology, and so on. The metallographic microscope is mainly used to identify and analyze the internal structure and organization of metals, and it is the key equipment for metallographic research and identification of product quality.
According to the optical principle, microscopes are divided into polarized light, phase contrast, and differential interference contrast microscope. Polarized light microscopy is used to identify the optical properties of the fine structure of substances. Any substance with birefringence can be distinguished clearly under a polarizing microscope. The most important feature of the phase contrast microscope is the ability to observe unstained specimens and living cells. Phase contrast microscopy utilizes the difference in refractive index and thickness between different structural components of an object to change the difference in light travel through different parts of the object into a difference in amplitude to observe the sample. The use of a differential interference contrast microscope not only observes colorless and transparent objects but also presents a relief of magnificent three-dimensionality for a more realistic observation.
Based on the orientation of the objective lens, microscopes are categorized into forward and inverted microscopes. And according to the type of light source, microscopes can be categorized into ordinary light, fluorescence, and laser microscopes. Moreover, according to the number of eyepieces, microscopes can be categorized as monocular, binocular, and trinocular microscopes.
