Our ARC anti-reflection coating is used whenever reflections from glass surfaces must be eliminated. The coatings offer a high optical light transmission and an excellent antireflection effect in the visible wavelength range. We achieve this by the use of an optical multi-layer coating adapting the refractive index of the glass substrate to the refractive index of the air. The result is that only a small part of the incident light is reflected. While an uncoated glass surface causes a reflection of about 8,5% in the visible wavelength spectrum, our anti-reflection coating layers can reduce these reflections in parts of this spectral light region to less than 0,2% per glass surface. Compared to a conventional single-layer anti-reflection layer with approx. 1-2% still reflected light this is a noticeable improvement that can be perceived with the naked eye. Our ARC anti-reflective coatings effectively suppress unwanted secondary reflections which overlay transmitted images and make them appear blurred. In transmission, this preserves a sharper and brighter image with significantly better contrast and higher optical image quality. When used as a laser window, double laser beams are suppressed, and the AR-coating layers increase light transmission.
We apply the layers of the double side coated ARC materials and of the single-side coated ARC–1S anti-reflection coatings to selected float glass substrates with a high-grade surface quality. For the ARC-B materials, we use BOROFLOAT® substrates. The refractive index of each multi-layer anti-reflection coating matches to the respective glass-air transition. Both ARC coating series are always available from stock as we produce them regularly. However, we do not restrict ourselves to the coatings, layers, and materials described above but can also apply anti-reflective coatings to other types of glass and optics by adapting the refractive index accordingly. A coating of glass lenses and other optics also is possible on a batch basis. Customized adaptation of coating layers for other operating wavelength ranges, infrared light or different refractive index is available on request.
We are not limited to a few standard dimensions! Our company specializes in the rapid production and delivery of optics with individual dimensions. We manufacture and deliver custom sized optics as fast as usually fixed dimensions can be delivered.

In case you want to get a batch of optical lenses anti-reflection coated, please let us know the exact specifications of the lenses you are supplying. It is essential to specify the refraction index of the lens material as well as the exact dimensions and focal length. The lenses to be coated must not already have a coating layer. Please specify the maximum allowed amount of light that still might be reflected (residual reflection) by the lens surface, the relevant wavelength area, and the light source used.
