There are many classifications of metallurgical microscopes. The specific classifications are as follows:
(1) Classification according to light source: halogen lamp metallographic microscope, infrared light metallographic microscope, incandescent lamp metallographic microscope
(B) According to the structure, there are: upright metallographic microscope, inverted metallographic microscope
(3) According to the light source lighting method, there are: reflection metallographic microscope (also called epi-metallographic microscope), transflective metallographic microscope
(D) According to the mesh number: monocular metallographic microscope, binocular metallographic microscope, trinocular metallographic microscope
(V) Classification by function: polarized metallographic microscope, dark field metallographic microscope, differential interference metallographic microscope, phase contrast metallographic microscope
(Six) According to the viewing mode: visual metallurgical microscope, video metallurgical microscope
(7) According to the size of the worktable, there are: large platform metallographic microscope, ordinary metallographic microscope
(8) According to the size of the machine: desktop metallographic microscope, horizontal metallographic microscope, vertical metallographic microscope, portable metallographic microscope (handheld metallographic microscope or on-site metallographic microscope)
This entry mainly introduces inverted metallographic microscope. Inverted metallographic microscope is usually divided into inverted polarized metallographic microscope, inverted phase difference metallographic microscope, inverted differential metallographic microscope, and inverted dark field metallographic microscope. The reason why the metallographic microscope becomes an inverted metallographic microscope is mainly determined according to the positional relationship between the worktable and the objective lens. Generally, the objective lens can be called an inverted metallurgical microscope under the worktable. Invert the fluorescence microscope. Because of the inverted structure, it also brings many advantages to this type of microscope: because the lens is under the work, it is not necessary to consider the flatness of the non-observing surface of the object when observing with the microscope, and because the inverted table top is empty, so There is no need to consider the height or size of the observed style. Because of these two significant advantages, the inverted metallurgical microscope is widely used in industrial enterprises that study metal materials or other solid bulk objects. However, because the lens is under the table, It is also commonly used to cause lens dust accumulation, which requires microscope users to maintain the microscope diligently to avoid affecting the observation effect due to the lens stain.
