Suppression of reflection by the help of physics

An 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 reflections is almost completely eliminated by our anti-reflection coatings. The natural surface reflection of a normal glass surface amounts to about 4,25%. This amount of reflected light can be reduced by our ARC coating series to below 0,2% in partial ranges of the visible wavelength spectrum. Compared with an ordinary single-layer anti-reflective coating which has residual reflections of for example 2% of light per surface this is a remarkable and visible improvement.


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 for technical optics applications in the visible wavelength spectrum.


Anti-reflection coatings on glass from stock or custom made

Our ARC anti-reflection 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 series, are always in stock, since we coat them at a regular basis. However, we are not restricted to these substrate materials. The ARC antireflection coating can be applied to virtually any suitable glass and the coating can be adapted to the corresponding refractive index of the substrate material that is used. 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 request a 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-reflection coatings are available from stock. Same applies for our our single-side anti-reflection coating called ARC–1S which is also based on our 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 for better vision. We do not coat eye-glasses or ophthalmic lenses at all. We only make technical grade coatings for the use as optical windows, lenses and substrates in technical optical applications. Also it is not practicable to coat a single lens or a single piece of glass. The coating of lenses and custom coatings are only possible if the quantities are large enough for at least one coating small run. Please use our information request form to inquire about whether your lens or custom coating will qualify for a customized coating run.
