Advanced Glass Substrate Magnetron Sputtering Optical Coating Equipment

Equipment Description

The magnetron sputtering coating equipment is suitable for coating various optical and decorative filmssuch as AR film, filter film, color film, high reflection film, NCVM or AF film on the surface of flat glass.glass lenses, mobile phone cover plates, plastic targets/sheets, mobile phone shells, and otherproducts.

Device Appliance

This product adopts reactive sputtering coating process, equipped with multiple sets of flat or rotatingsputtering cathodes, and uses DC or intermediate frequency sputtering power supply. The equipment issuitable for coating multi-layer optical films, equipped with an evaporative coating device, and can alsoachieve the coating of AF films, Coated products are widely used in consumer electronics such asmobile phones, tablets, wearables, and laptops. They can also be used in various fields such as carphone back cover, home appliances, and diamond jewelry. At the same time, it has the advantagesof large effective coating area, large loading capacity, high efficiency, stable process, goodrepeatability and stability,and good film adhesion.

Core Components

1. Vacuum System: Provides a high-vacuum environment for coating to prevent gas molecules from affecting film purity. Its core components include a vacuum pump set, a vacuum chamber, and a vacuum gauge.
2. Magnetron Sputtering Target System: Generates plasma to bombard target materials (e.g., metals, oxides), causing target atoms to deposit on the substrate surface. It can be equipped with multiple target positions to realize multi-layer coating.
3. Substrate Holding and Transmission System: Fixes optical substrates (e.g., glass, lenses) and ensures coating uniformity through uniform rotation or translation. It supports the adaptation of substrates of different sizes.
4. Control System: Uses PLC or computer programs to control parameters such as vacuum degree, sputtering power, and coating time, enabling automated and high-precision coating processes.

Core Advantages

High Film Quality: The films have high density and strong adhesion, with stable optical properties. This effectively reduces issues such as film peeling or performance degradation.
High Coating Efficiency: The magnetron sputtering technology has a faster deposition rate, making it suitable for mass production. It also supports uniform coating on large-area substrates.
Wide Material Compatibility: It can sputter various target materials, including metals, oxides, and nitrides. It can produce multiple types of optical films, such as anti-reflection films, reflective films, and light-filtering films.

Typical Application Fields

Optical Component Field: Prepares anti-reflection films for camera lenses, telescope lenses, and eyeglass lenses to reduce light reflection loss.
Display Field: Prepares conductive films (e.g., ITO films) or light-filtering films on the glass substrates of LCD and OLED screens to improve display performance.
Photovoltaic Field: Prepares anti-reflection films on solar cell glass to enhance light absorption efficiency.
Laser and Infrared Field: Prepares high-reflection films or narrow-band light-filtering films for laser lenses and infrared detectors to ensure optical performance.
