The principle of
1. film thickness gauge The
film thickness gauge is an instrument specially used for measuring the thickness of thin films. Its principle is based on optical interference. Its main working principle is to use the wavelength of a monochromatic light source to reflect light between the air and the film. Form interference fringes. The

film thickness meter judges the surface morphology of the object to be measured by the morphology of the interference fringes, so that the thickness of the film can be measured. It can be divided into two types: single-arm and double-arm. The measurement accuracy of single-arm film thickness meter is generally within 0.1 nanometers, while the double-arm film thickness meter can achieve higher accuracy, about 0.01 nanometers.

2. Film Thickness Meter Features

1. High precision: Film thickness meter can accurately measure the thickness of thin films at the nanometer level.

2. Rapid measurement: The film thickness meter has a fast measurement speed and can quickly obtain the thickness of the film.

3. Easy to use: The film thickness gauge is simple in design, easy to operate, and very convenient to use.

4. Widely used: Film thickness meter has a very important application in the production process of coating, chemical evaporation, physical vapor deposition, etc.

3. film thickness meter application

film thickness meter is widely used in various fields, especially in materials science, optics, electronics, chemistry, biomedicine and other research fields.

For example, in the field of coating, the film thickness gauge can be used to measure the thickness of the coating to ensure the uniformity of the coating and the corrosion resistance and wear resistance; in the cosmetics industry, the film thickness gauge can be used to measure the thickness of the cosmetics, To ensure the maximum use of raw materials without affecting the use effect; in chemical production, the film thickness gauge can be used to measure the thickness of the reactant during vapor deposition to ensure the quality of production. The wide application of

film thickness meter makes it one of the indispensable measuring instruments in modern industry and scientific research. At the end of the

: Through the introduction of this paper, we can see that the film thickness meter, as a new type of high-tech measuring instrument, has the characteristics of high precision, fast measurement, easy to use and wide application, has an important position and role in the field of film preparation, and with the development of technology and in-depth research, the film thickness meter will play a greater role in the future science and technology and industry.
