  • Coating for lenses and lens assemblies

Our optical ARC-anti-reflection coating is deposited on the surface of high-quality glass substrates. The material offers a high light transmission and a very good anti-reflection effect in the visible wavelength range.

Uncoated glass has natural surface reflections of about 4.25% per side. These are reduced by our ARC coating in parts of the visible spectral range to below 0.2% per glass surface. Compared to single-layer antireflective coatings with a typical 1-2% residual surface reflection, this is a clearly perceptible improvement.

Reflective surfaces of uncoated, transparent glass can cause secondary reflections which overlay a transmitted image with so-called "ghost images". The ARC-coatings almost completely suppress this ghosting effect.

The coating system of our ARC-coatings is based on thin layers with different refractive index. These layers are alternately coated one over the other. The thickness of the respective layer is selected in such a way, that for the reflected light destructive interference is caused and the light to be transmitted is subjected to constructive interference. The result is an effective antireflection effect and increased light transmittance.

Antireflective coatings for visible and invisible wavelengths are used in many everyday applications. Most eyeglasses, camera lenses and display-front-panes for example use simple anti-glare layers. But especially in the field of technical optics an optical anti-reflection coating is often indispensable since an uncoated glass or lens can distort measurement results or produce blurry images. The coating of our ARC-coating is deposited on high-quality glass substrates and it is mainly used for technical optical applications.

The ARC-coatings are applied to selected float glass material with mirror quality and they are adapted to the refractive index of the substrate glass. The ARC-B-series is based on the borosilicate glass BOROFLOAT®. The refractive index is also matched to the substrate material. Both ARC-coating series are continously available from stock, as we regularly produce them.

We are not limited to the anti-reflective layers described above. If desired and if a sufficient quantity is needed, an anti-reflection coating can be applied to any other suitable glass, lens or to any kind of optics. Also the coating of glass lenses is possible on a batch basis. Optimization for other wavelength ranges or a different refractive index can be realized. And of course other angles of incidence and centered wavelength anti-reflection coatings for lasers are optionally can be fabricated.


How do I get a quote and are there standard dimensions?

We are independent of standard dimensions. Our company has specialized in manufacturing and delivering individual dimensions as fast as it is usually only possible with standard dimensions. If you would like to request one of our ARC standard anti-reflection coatings on glass with individual dimensions, please simply use the following button:

Note: We are often asked if we also do anti-reflection coatings for eyeglass lenses. The anti-reflective coating of spectacle lenses is not part of our production program. We have specialized exclusively in the antireflection coating of technical glass for optical applications.
