Chọn chất liệu tem nhãn: Chất liệu tem nhãn cần được lựa chọn phù hợp với loại sản phẩm và mục đích sử dụng.
Specially geared up products samples may be considered from the TEM. The light microscope and TEM are commonly made use of along with each other to enrich a analysis task.
The theoretical resolution explained by Abbe for the light microscope could be modified and placed on the TEM by using DeBroglie's system. DeBroglie said that the wavelength of the electron beam can be a function of the accelerating voltage applied.
The conversation of electrons with the sample is another distinguishing component. In SEM, the principal concentrate is on the electrons which are scattered off or emitted through the surface area of the specimen. These interactions enable kind pictures that reveal the topography and elemental composition on the sample.
The roughing pump is usually utilised multiple moments throughout a session to pump out the specimen load lock chamber in advance of it enters the extremely-superior vacuum ecosystem with the column. Roughing pumps may also be used to “back again” specified substantial vacuum pumps, providing yet another layer of pumping.

The many electrons will for that reason not achieve a standard point website of interest. To lower spherical aberration, an aperture is accustomed to do away with some of the periphery electrons.
The organization from the transmission electron microscope (TEM) is analogous to that of the light microscope.
Due to the fact the main demonstration of electron optics inside the early 1930s, virtually a century of investigation and growth has culminated, setting up TEM as an indispensable technique for each supplies and life science apps.
