Our ARC anti-reflection coatings are used whenever reflections from glass surfaces must be eliminated. The coatings offer a high optical light transmission and a very good anti-reflection effect in the visible wavelength range. This is achieved by the use of an optical multiple-layer coating adapting the refractive index of the glass substrate to the refractive index of the air. The result is that only a very small part of the incident light is reflected. While an uncoated glass surface shows a reflection of about 8,5% in the visible wavelength spectrum, our anti-reflection coating can reduce these reflections in parts of this spectral light range to less than 0,2% per glass surface. Compared to conventional single-layer anti-reflection coatings with approximately 1-2% of light still reflected this is a noticeable improvement that can be seen with the naked eye. Unwanted secondary reflections which overlay transmitted images and make them appear blurred are effectively suppressed by our anti-reflective coatings. In transmission this preserves a sharper and brighter image with significantly better contrast and significantly higher optical image quality.
The ARC-anti-reflection-coating is applied to selected float glass substrates with high grade surface quality. For our ARC-B-series we use BOROFLOAT® substrates. The refractive index of the respective multiple-layer anti-reflection coating is matched 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 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 coating layer adaptation for other operating wavelength ranges or a different refractive index are available on request.
We are independent of standard dimensions because our company is specialized in the fast production and delivery of individually sized optics. 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 important to specify the refraction index of the lens material as well as the exact dimensions and focal length of the optical lenses. 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), the relevant wavelength area, and the light source used.
