Anti Reflective Sheet

Your Trusted Anti Reflective Coating

Anti Reflective Sheet

Anti-reflective sheet refers to the anti reflective coating applied to a surface, such us telescopes, car center console, car displays, with transparent materials like Polycarbonate Sheets, (PMMA)Pexiglass, to reduce the amount of light reflected off the surface.

Excelite anti-reflective coating sheets are thin film coatings applied to the sheet. It has one or more layer Nanoscale grade coating on the surface of sheet making the screen much more clarity by improve the light transmittance and reduce the light reflection .

Anti Glare Sheet Vs. Anti Reflective Sheet

Type of Reflection: Anti-glare sheet focuses on reducing direct light reflections (glare), while anti-reflection sheet deals with minimizing reflections at the interface between different materials.
Surface Texture: Anti-glare coatings often involve a slightly textured surface to disperse light, while anti-reflection has a glossy surface.
Applications: Anti-glare is commonly found in displays and screens, where direct light can cause glare. Anti-reflection is more prevalent in optical applications, such as camera lenses, telescopes and eyeglasses, where the focus is on improving visual clarity.

Customized Anti-Reflective (AR) Sheet Design for Optical Equipment

Excelite’s anti-reflective (AR) sheet is applied for specific wavelengths of light. The design of these sheets can be customed to the visible light range (approximately 400-700 nanometers), as well as for specific wavelength ranges such as infrared or ultraviolet light. Depending on the desired application and the requirements of the optical equipment, the anti-reflective sheet can be designed to target a single wavelength or multiple wavelengths of light.

One or Two more Layers Antireflective coating treatment

Antireflection coatings reduce surface reflection through destructive interference between reflections from the coating surface and coating-substrate interface. Multilayer(more than two layers) anti-reflection coatings can further lower reflectance by optimizing the phase and intensity of reflected light waves from multiple interfaces.

Questions to ask yourself before requesting a coating

Is it a consumer goods application or for optical and electronic displayers, smart touch screens and systems?
Which wavelengths, or wavelength ranges are you working at?
What level of transmission/reflectance is required?

Typically:

AR >96% transmission (<4% reflection)
VAR/BBAR/WAR >99% transmission (<1% reflection)
A+3, B-3

Anti-Reflective polycarbonate Sheet Application

Anti Reflective Coating Car Display

Excelite Anti reflective Coating Car Display is a polycarbonate sheet with anti reflective coating, providing reflections and improve visibility on curved automotive screens and displays. By minimizing distracting reflections off panels, Excelite coatings allow for better image clarity and contrast, improving driving safety.

Optical Devices with VR Vision

Excelite offers precision anti-reflective coatings to take VR headset to the next visual level through advanced nanoscale technology.

Medical Equipment With AR Sheet

The use of Excelite AR coatings helps improve imaging, measurement precision and overall functionality for a wide variety of medical testing and examination equipment.

Outdoor Signs and Displays

When applied to materials like polycarbonate sheets used for signs, the coating helps cut down on glare without compromising transparency. This makes signs and displays much easier to see clearly even in direct sunlight.

Electronic Devices

Polycarbonate anti reflective screen used for the protective panel of smartphones, tablets, and laptops and other electronic devices, which can reduce the amount of reflective light, making it easier to use the device and reducing eye strain.

Anti Reflective Optical Equipments

The application of polycarbonate anti-reflective lenses on cameras, telescopes, and binoculars, enhancing visibility and facilitating clearer viewing.

Anti-reflective coating processing

There are different technologies to the reflective resistant, which includes dip coating, spin coating, Physical Vapor Deposition(PVD), Plasma enhanced chemical deposition(PECVD) and so on. PVD, is the most commonly used method for applying anti-reflective sheets due to the strong bond between the thin film and the substrate.

Before finish an antireflective polycarbonate sheet or acrylic sheet, it starts with applying a hard coating to enhance the durability and scratch resistance of the product, especially acrylic sheet.

First, following the thermal bending process, the product may go through a silk-screen printing step to add any necessary designs, logos, or information onto the surface.

Once the silk-screen printing is complete, the product is then ready for cutting to its final dimensions.

Finally, the last step in the processing of anti-reflective products is the application of a protective film. Anti-reflective coatings can be applied as either single-sided or double-sided, depending on the intended use and application of the product. When the anti-reflective product is intended to be adhered to a screen or surface, typically only a single-sided AR (Anti-Reflective) coating combined with AF (Anti-Fingerprint) treatment is needed.

Anti Reflective Treatment to Polycarbonate Sheets or Acrylic Sheets

AR coatings are designed to minimize the amount of light that reflects off the surfaces of polycarbonate sheets. This is achieved by applying one or more thin layers of material with specific refractive indices. These layers are engineered to cause destructive interference with the light reflected from the surface of the polycarbonate and the coating itself, effectively canceling out the reflections. As a result, more light passes through the polycarbonate sheet, significantly improving transparency and reducing glare.

What is anti reflective coating for polycarbonate?

Polycarbonate non reflective sheet is a type of plastic material that has been treated with an anti reflective coating. This coating reduces the amount of glare that is reflected off of the surface of the material, improving visibility and reducing eye strain. AR Coating technology is using the principle of optical interference to sink one or more layer Nanoscale grade medicinal coating on the surface of sheet which is often together with AF coating making the screen much more clarity.

EXCELITE is with advanced coating equipment and technology passed ISO 9001:2015, ISO45001:2018 and ISO 14001:2015. Our AR+AF coating has been widely used in car dashboard panels and other screens.

Benefits of Polycarbonate sheet anti reflective protection

Improved Visibility: By reducing surface reflections, AR coatings enhance the clarity and visibility through polycarbonate sheets, making them ideal for applications such as protective visors, eyewear lenses, and transparent barriers.
Reduced Eye Strain: In applications where individuals must look through polycarbonate lenses or shields for extended periods, AR coatings can help reduce eye strain by minimizing glare.
Enhanced Durability: Polycarbonate sheets are already known for their impact resistance and durability. When combined with AR coatings, which can also provide additional scratch resistance, the result is a highly durable material suitable for harsh environments.
Increased Light Transmission: AR coatings allow for higher light transmission through polycarbonate sheets, which is particularly beneficial for applications like solar panels, greenhouse panels, and anywhere else where maximizing light penetration is desired.
