PrepARation of ar antireflection coating

Preparation of AR antireflection coating —— Optical glass ——YMUS ultrasonic spraying

Anti-reflection film, also known as anti-reflection film or AR anti-reflection glass (anti-reflection glass or anti-reflection glass), is a kind of coated glass, which is deposited on the surface of optical elements to reduce surface reflection and increase the transmittance of optical system. The working band can be from extreme ultraviolet region to far infrared region, and can be divided into single-wavelength, multi-wavelength and broadband anti-reflection films according to the working band range, but the most widely used is the visible light band anti-reflection film. The function of visible antireflection film is to reduce the intensity of reflected light, thereby increasing the intensity of transmitted light and making the imaging of optical system clearer. Its principle is to eliminate incident light and reflected light by using the interference effect produced by different optical material films, so as to improve the light transmittance. There are two processes: single-sided coating and double-sided coating.  

Mainly used in LED display screen, touch screen, LCD projection system, glasses incoming coating, instrument window, fingerprint analyzer window, monitor protective mirror, antique frame window, high-end watch window, glasses, silk-screen optical glass products.

The application of ultrasonic spraying anti-reflection (AR) antireflection solution on glass is mainly to reduce the reflectivity of glass surface and improve the light transmission performance. AR antireflection coating is usually formed by depositing a layer of material with low refractive index on the glass surface.

Advantages and disadvantages of ultrasonic spraying AR antireflection solution on glass;  

1. Improve the light transmittance: AR antireflection coating can reduce the reflectivity of the glass surface, so that more light can pass through the glass and improve the light transmittance. This is very important for applications that need to transmit light, such as displays and optical devices.  

2. Reduce reflection and glare: AR antireflection coating can reduce the reflection on the glass surface, thus reducing the generation of reflection and glare. This makes it clearer and more comfortable to observe or use the scenery or information in front of the glass, and reduces visual fatigue.  

3. Improving optical properties: AR antireflection coating can improve the optical properties of glass, such as reducing dispersion effect and improving contrast. This is very important for applications that require high-quality optical performance, such as lenses, optical instruments, displays, etc.  

4. Anti-pollution and durability: AR antireflection coating can protect the glass surface, resist the adhesion of pollution, and make the glass easier to clean and maintain. In addition, this kind of coating usually has good durability and is not easy to wear or fall off, which increases the service life of glass.  

5. Wide applicability: In the process of coating preparation, ultrasonic spraying technology can be applied to glasses of various shapes and sizes, which greatly improves the flexibility and efficiency of the process.

The preparation of YMUS ultrasonic spraying AR anti-reflection solution coating requires professional equipment and technology, and the quality, thickness and uniformity of the coating can be precisely controlled. The invention relates to a conveying type automatic ultrasonic precise spraying machine, which is a mass production type automatic ultrasonic spraying equipment. It can be equipped with a wide spraying type ultrasonic nozzle, and can be equipped with a plurality of nozzles to work in parallel at the same time. The equipped automatic conveyor can automatically convey samples, and is especially suitable for mass production and large-area film spraying. Such as fuel cell membrane electrode spraying, various glass coating, thermal insulation film spraying, AR anti-reflection film spraying, photoresist spraying, transparent conductive film spraying, super-hydrophobic coating spraying, etc.
