The plasma cleaning machine ionizes gases (such as oxygen, argon, etc.) and forms a plasma composed of ions, electrons, free radicals, etc. in a vacuum chamber through radio frequency power or microwave power. Under the action of an electric field, high-energy ions in the plasma accelerate their impact on the surface of the lens, breaking the molecular bonds of pollutants and causing them to peel off.

Plasma cleaning technology involves a chemical reaction between active free radicals and pollutants on the surface of the lens, producing volatile gases (such as CO ?, H ? O) to achieve residue free cleaning. The decomposed pollutants are discharged from the chamber through a vacuum pump to complete the cleaning process.

Next, let's delve into the application role of plasma cleaning machines on lens surfaces?

The plasma cleaning machine can effectively remove organic pollutants, grease, dust and other impurities on the surface of the lens, achieving atomic level surface cleaning. The surface of the lens after plasma cleaning forms a slightly rough surface, increasing surface activity, which is conducive to better bonding the coating material with the lens surface, improving the adhesion and durability of the coating.

Plasma processing machines can not only inject hydroxyl functional groups into the surface of lenses, changing the hydrophobic state of the lens surface to a hydrophilic state and improving wettability, but also remove small defects and pollutants on the lens surface, reduce scattering and absorption of optical materials, and improve their transparency and optical performance.

The plasma cleaning machine is applied to the following accessories in the field of optics:

1. Optical components: Low temperature plasma cleaning machine can remove organic matter, oil stains and dust on the surface, ensuring the optical performance and processing quality of optical components. At the same time, it cleans optical components (such as optical lenses and optical components). This cleaning method is not only efficient, but also can avoid damage to the surface of the components.

2. Deposition of optical films: Plasma cleaning can clean the substrate surface, improve the adhesion and uniformity of the film, thereby optimizing the optical properties of the film, and then deposit the optical film. For example, the surface of optical lenses treated with low-temperature plasma cleaning can significantly improve the adhesion and uniformity of the coating.

3. Surface modification: Low temperature plasma cleaning can perform surface cleaning and activation modification treatment on various optical materials such as glass, plastic, and metal. By low-temperature plasma treatment, the polarity and chemical composition of the surface can be changed, thereby altering the wettability and hydrophilicity of the surface, and improving the corrosion resistance and wear resistance of the material.

4. Improve optical performance: Plasma cleaning can remove grease, dust, and particles from the surface of optical components, reduce damage and impact on optical components, and thus improve the performance and lifespan of optical systems. In addition, plasma cleaning can also form hydrophilic groups on the surface, enhancing the adhesion of the coating.

Linear wide width plasma cleaning machine is an environmentally friendly dry cleaning technology that does not use chemical solvents. Wide width plasma cleaning technology can process surfaces of small sizes and complex shapes, ensuring the high quality of optical components and manufacturing micro nano optical devices and integrated optical devices. 

In summary, plasma cleaning machine is an essential step before optical lens cleaning because it can remove small pollutants and molecular atomic groups on the surface of the lens, making the surface more hydrophilic and conducive to subsequent coating deposition.

In summary, the application of low-temperature plasma cleaning technology in the field of optics has significant advantages, which can improve the cleanliness, optical performance, and service life of optical components, meet environmental requirements. Due to its high efficiency, environmental friendliness, and non-destructive characteristics, plasma cleaning equipment is widely used. 

It can not only remove pollutants, but also increase surface hydrophilicity and adhesion, which is very beneficial for subsequent coating or bonding processes and can significantly improve the performance and quality of optical components.
