Our optical ARC anti-reflection coatings on high-quality glass substrates offer a high transmission and a very good antireflection effect in the visible wavelength range.
Uncoated glass has a natural surface reflection of about 4.25% per side. This is reduced by our ARC coatings in parts of the visible spectral range to below 0.2% per glass surface. Compared to single-layer AR-coatings with a typical 1-2% residual reflection, this is a clearly perceptible improvement.
Reflective surfaces of uncoated, transparent glass cause secondary reflections, that superimpose transmitted images with so-called "ghost images". The ARC coatings almost completely suppress this ghosting effect.
The coating system of our antireflection 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.
Anti-reflection coatings for visible and invisible wavelengths are found in many everyday applications. Most eyeglasses, camera lenses and display front glasses etc. for example have simple AR layers. But, especially in the field of technical optics, optical antireflection coatings are often indispensable, since uncoated glasses or lenses can distort measurement results or produce blurry images. Therefore, the coating of each ARC antireflection coating is based on high-quality glass substrates and is mainly used for technical optical applications.
The ARC coatings are applied to flat, selected float glass with mirror quality. The ARC-B series is based on a high-quality, selected borosilicate glass. Both ARC coatings are always available as standard, as we regularly produce them.
We are not limited to the layers described above. If desired and if a sufficient quantity is needed, anti-reflection coatings can be applied to any other suitable glass and to any suitable optics. Also the coating of optical lenses is possible on a batch basis. Optimizations for other wavelength ranges, angle of incidence or center of gravity coatings for lasers are also feasible.
We are independent of standard dimensions and have specialized in manufacturing and delivering individual dimensions as fast as is usually only possible with standard dimensions.

Note: We are often asked if we also do anti-reflection coatings for eyeglasses. 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.
