Suppression of reflection by the help of physics

Our anti-reflection coating consists of alternating, thin-film-coated layers with different refractive index. The thickness and the refractive index of each layer is chosen, to generate a self-extinguishing interference for the light reflected by the surface and to cause constructive interference in the associated transmitted light beam for a defined wavelength range. The highly efficient broadband-multilayer coating system of our ARC is adapted to the refractive index of air. It can drastically reduce the reflection, which for physical reasons occurs on uncoated or blank glass surfaces. At the same time our antireflection coatings greatly increase the light transmission of a glass or a glass lens, because the vast majority of the light which is normally reflected, is available in transmission.


Eliminating ghosting & increasing light transmission

The reflective surface of a blank glass causes secondary reflections that are superimposed on a transmitted image. This usually is the cause for ghost imaging. This undesirable effect of residual light reflection is almost completely eliminated by our AR-coatings. The natural surface reflectivity of a normal glass surface amounts to about 4,25 %. This amount of reflected light can be reduced to below 0,2 % in partial ranges of the visible wavelength spectrum by our ARC coatings. Compared to an ordinary single-layer anti-reflective coating which has residual reflections of for example 2 % of light per surface, this is a technically remarkable and visible improvement for the eye.


AR-coatings are omnipresent

Anti-reflective coatings are often used in everyday life applications like eye-glasses, magnifying lenses, camera lenses, optical lenses, quality display glass, automotive cockpit windows etc to suppress reflections. However, the type of AR-coating used for such applications usually doesn't provide the high effectiveness and high quality of our ARC anti-reflection coatings. All our AR-coated ARC materials are based on premium-quality glass substrates and the primarily use is as technical optics for applications in the visible wavelength spectrum.


Anti-reflection coatings on glass from stock or custom-made

Our ARC anti-reflective coating series are vacuum deposited on flat, premium grade white float glass. The ARC-B series is coated on selected high quality borosilicate glass. The AR-coating is matched to the index of refraction of the respective glass material and to the one of air. Both ARC-coating materials are always in stock since we coat them at a regular basis. However, we are not restricted to these substrates. The ARC anti-reflective coatings can be applied to virtually any suitable glass and the coating can be adapted to the corresponding refractive index of the substrate materials that are used to create the best possible solution. Of course, our ARC layers can be applied to glass lenses too and all of our ARC anti-reflection coatings can be optimized for other wavelength ranges, another index of refraction, specific laser lines or even lower rest reflections or for an even higher light transmission. Please use our inquiry form to contact us and request your custom coating, in case you want to get a quotation for a customized anti-reflection coating that fits your application or to get batch quantities of glass lenses AR-coated. Our standard ARC anti-reflective coatings are available from stock. Same applies to our our single-side anti-reflection coating called ARC–1S, which is also based on high quality selected float glass.


How can I order stock sizes?

You might be wondering why we do not have a shop system on our website. For this, there is a simple reason. We are not dependent on a few stock dimensions, as is often the case with resellers who do not have their own production. We specialized on being able to manufacture and supply customer-defined dimensions as fast as commonly catalog items ship.

Note: We often get inquiries to coat eye-glasses with anti-reflective layers for better vision quality. We do not coat eye-glasses or ophthalmic lenses at all. We only make technical grade coatings for optical windows, lenses and substrates for technical optical applications. Also, it is not practicable to coat a single lens or a single piece of glass. The coating of lenses and any kind of custom coatings are only possible if the production quantities are large enough for at least one small coating run. Please use our contact form form to inquire information about whether your lens or custom coating will qualify for a customized coating run.
