Our anti-reflection coatings consist of alternating thin-film-coated layers, each with a 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. The coatings can drastically reduce the reflections, which for physical reasons occur on uncoated or blank glass surfaces. At the same time it greatly increases the light transmission of a glass or a glass lens, because most of the light which is normally reflected, is available in 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-coating. The natural surface reflectivity of a normal glass surface sums up 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 standard ARC-coating. Compared to ordinary single-layer AR-coatings which has residual reflections of for example 2 % of light per surface, this is a technically remarkable and visible improvement for the eye.
Anti-reflection 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 glare effects. However, the type of AR-coatings used for such applications usually doesn't provide the high effectiveness and high quality of our ARC anti-reflection coating. All our ARC-materials are based on premium-quality glass substrates and their primarily use is for technical optics applications in the visible wavelength spectrum.
Our ARC anti-reflection coating series is vacuum deposited on flat, premium grade white float glass material and our ARC-B series is based 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 at several thicknesses since we coat them on a regular basis. However, we are not restricted to these substrate materials and also a custom glass thickness is possible if the quantity is large enough to fill one coating run. The ARC-coatings can be applied to virtually any suitable glass and it can be adapted to the corresponding refractive index of the substrate material that is used, to create the best possible solution. Of course, our ARC multi-layer coating can be applied to glass lenses too and all of our anti-reflection coatings can be optimized for other wavelength ranges, a different index of refraction, specific laser lines, even lower rest reflections or for an even higher light transmittance. Please use our inquiry form to request a quote for a customized anti-reflection coating or for pricing to get your glass lenses AR-coated. Our standard ARC anti-reflection coated glass materials are available from stock. Same applies to our our single-side coating called ARC–1S, which is also based on high quality selected float glass material.
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. 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 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 coating are only possible if the production quantities are large enough for at least one small coating run. Please use our information request page form to inquire information about whether your lens quantity or custom coating size will qualify for a customized coating run.
