There are two types of anti-reflective glass: interference-optically coated glass and chemically etched glass.
“Anti-reflective glass” or “anti-glare glass” is a type of technical glass that is specially treated to minimize light reflection. This treatment reduces the amount of reflected light, preventing glare and increasing light transmission.
The surface of anti-reflective glass is either chemically etched or coated with multiple thin layers, usually of metal oxides, which scatter light or reduce reflected rays. This allows for a clearer view of what is behind the glass without being disturbed by annoying reflections.
Applications for anti-reflective glass can be found in various fields such as monitors, touch screen displays, electronic device screens, camera lenses, showcases, and other optical devices or display surfaces where clear visibility and minimized reflections are important.
The best type of anti-reflective treatment for your application depends on the area of use and other technical specifications. To choose the best material for your needs, please contact us, and we will be happy to advise you.
Regarding technical flat glasses, such as those used in displays in advertising pillars, passenger information systems, medical devices, maritime displays, or other display systems, interference-optical anti-reflection plays a crucial role. The main purpose is to reduce disturbing reflections from about 8% to less than 1% and to increase the transparency of the glass to provide a clear view and an improved visual experience.
The anti-reflection of flat glass is achieved by applying thin metal oxide layers to the glass surface using various coating processes. These layers are designed to influence light in a specific wavelength range, usually in the visible light spectrum. Similar to other optical applications, the effect is based on the principle of interference.
When light hits the coated glass surface, the layers are designed to minimize reflections by influencing the interfering waves in a way that they cancel each other out or weaken. The result is reduced light reflection on the glass surface, allowing more light to pass through.
Interference-optical anti-reflections for flat glass can be used in various environments, from residential and commercial buildings to vehicles and electronic displays. This technology helps minimize glare effects, improve visibility, and enhance the quality of images or text on displays. It’s essential to note that the specific requirements for anti-reflection can vary depending on the application, and the coatings must be adjusted accordingly.

The term chemical etching or etched anti-reflection refers to a process where the glass surface is treated with a specialized etching chemistry to reduce reflections.
This process is commonly used in technical glasses such as displays, monitor screen protectors, touch input systems, and other technical glasses.
Etching is performed on a microscopic level to create tiny irregularities that scatter the incident light diffusely, thus preventing distracting reflections. This is crucial in optical systems where clear visibility is required, and reflections could compromise image quality. A prerequisite for this method is that the protective glass is flush with the display.
Chemical anti-reflection coatings have the advantage of positively influencing the tactile feel of the glass surface, making fingerprints or dirt less visible.
Depending on requirements such as display resolution, different gloss values or etch grades can be achieved.
Etched anti-reflection improves the surface’s light transmittance and reduces glare, resulting in an enhanced image, particularly in conditions with strong ambient light.
