Technical parameters and definitions of inverted metallographic microscopes
There are many classifications of metallographic microscopes, the specific classifications are as follows:
(1) Classified by light source: halogen lamp metallographic microscope, infrared light metallographic microscope, incandescent lamp metallographic microscope
(2) According to structure, they are divided into: upright metallographic microscope, inverted metallographic microscope
(3) According to the light source illumination method, there are: reflection metallographic microscope (also called epi-illumination metallographic microscope), transmission-reflection metallographic microscope
(4) According to the number of eyes, there are: single-eye metallographic microscope, binocular metallographic microscope, and trinocular metallographic microscope.
(5) Classified by function: polarizing metallographic microscope, dark field metallographic microscope, differential interference metallographic microscope, phase contrast metallographic microscope
(6) Classification according to viewing methods: visual metallographic microscope, video metallographic microscope
(7) According to the size of the workbench, there are: large platform metallographic microscope, ordinary metallographic microscope
(8) According to the size of the machine, there are: 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 microscopes. Inverted metallographic microscopes are usually divided into inverted polarizing metallographic microscopes, inverted phase contrast metallographic microscopes, inverted differential metallographic microscopes, and inverted dark field metallographic microscopes. The reason why a metallographic microscope is called an inverted metallographic microscope is mainly determined by the positional relationship between the workbench and the objective lens. Usually, if the objective lens is under the workbench, it can be called an inverted metallographic microscope. If it is another microscope, it is called an inverted biological microscope. Inverted fluorescence microscope. Because of the inverted structure, this kind of microscope also brings many advantages: because the lens is below the working surface, there is no need to consider the flatness of the non-observation surface of the object when observing with the microscope, and because there is an open space above the inverted table, There is no need to consider the height or size of the object being observed. Because of these two significant advantages, inverted metallographic microscopes are widely used in industrial enterprises that study metal materials or other solid bulk objects. However, because the lens is under the workbench, It is also usually used to cause dust to accumulate on the lens, which requires microscope users to maintain the microscope frequently to prevent lens dirt from affecting the observation effect.
