Our ARC coatings offer excellent anti-reflection performance and high optical light transmission for the visible wavelength range. The vacuum-deposited dielectric multi-layer coatings adapt the refractive index of the substrate to the ambient air. As a result, the coating layers reduce the reflection from glass surfaces to a minimum.
Typically in the visible wavelength spectrum, about 4,25% of light is reflected from each uncoated glass surface. So, around 8,5% of the light is lost per uncoated element in an optical system through reflection caused by a refractive index mismatch. Our ARC coating reduces such reflections in parts of this spectral range to less than 0,2% per surface, which is considerably better than simple single-layer anti-reflective coatings that often reflect 1-2% of light.
The so-called ghost imaging is another unwanted effect in optical systems caused by the natural surface reflection. A transmitted image is superimposed with a reflected weak identical ghost image, resulting in degraded sharpness and blurry imaging. The ARC broadband anti-reflection coating suppresses such unwanted secondary reflection effectively. Hence, the transmitted image remains sharper and brighter and offers much better contrast. Imaging accuracy is maintained, and nearly no light gets lost by reflection. Our ARC coating materials can also reduce a secondary laser beam when used as a laser window. The usable light power increases because the entire laser beam's energy is transmitted.
We apply the coating layers of our double-side coated ARC and single-side AR-coated ARC-1S standard AR-coatings on selected iron-reduced float glass materials using a vacuum deposition process. For the ARC-B coating, we use premium-grade borosilicate glasses. We ensure the best light transmission by adapting the refractive index of each anti-reflection coating to the respective substrate material.
All ARC coatings are usually always available, as we produce them regularly. Our coating capabilities are not limited to the anti-reflection coatings described on this website. On request, we also coat other substrate materials or finished optics. We also apply our anti-reflective coating layers to optical lenses and other optics the customer provides on a per-batch basis. On request, a customized AR-coating for a different wavelength range is also available.
Our company specializes in rapidly producing and delivering optics of individual sizes. We can quote, fabricate, and provide custom-sized optics as fast as off-the-shelf parts with fixed dimensions usually can ship. Hence, you can order precisely the sizes you need at any time! Our strength is the rapid custom manufacturing of optics that perfectly fit your applications without any modification.

If you want us to custom coat our anti-reflection coating on supplied lenses, please let us know the exact specifications. Specifying the lens material's refraction index, the precise lens dimensions, and focal length is essential. The provided lenses must not already have any coating layers on their surfaces. Please inform us about the lens glass materials, maximum allowed residual reflection of the lens surface, the relevant wavelength range, and the light source you plan to use. Please consider that such custom coatings are only possible in production quantities.
All given details and specifications are mean reference values and are not guaranteed. Also, please consider our "Notes on specifications".
