Anti-reflection coatings minimize reflections from glass surfaces. To offer excellent anti-reflective properties and high optical light transmission in the visible wavelength range, we have developed our ARC coating series. The ARC-coatings are vacuum-deposited, multi-layer dielectric thin-film coatings whose layers adapt the refractive index of the substrate to the refractive index of the ambient air. As a result, the reflections reduce to a minimum.
The surfaces of uncoated glass show a typical reflection of approximately 4,25% per side, so in total, 8,5% of light in the visible spectrum is reflected. Our ARC coating layers can reduce these reflections in parts of this spectral range to less than 0,2% per surface. Compared to conventional single-layer anti-reflection coatings, which typically still reflect about 1-2% of the incident light from each side, this is a considerable improvement.
Also, our ARC anti-reflection coatings effectively suppress unwanted secondary reflections. Such reflections often overlay a transmitted image with a weak identical image and make it appear unsharp. By using our ARC coating, the image remains sharper, brighter, and offers significantly better contrast, so the image quality is maintained, and almost no light gets lost. When used as a window for a laser beam, double laser beams are suppressed by our ARC layers as well, and the available laser power increases since almost no light is reflected and therefore available in transmission.
The layers of our double-sided coated ARC and single-side coated ARC-1S materials are applied to high-quality selected iron-reduced float glasses by a vacuum deposition process. For the ARC-B series, we use selected BOROFLOAT® substrates. We adapt the refractive index of each anti-reflection coating to the respective material used. The ARC coating series are usually always available from stock, as we manufacture them regularly.
We are not limited to the anti-reflection coatings described here. On request, we also coat other substrate materials and finished optics. We can adapt the refractive index of our anti-reflection coatings to the respective carrier glass. We also have the capabilities to coat optical lenses and other optics provided by the customer with our anti-reflection coatings on a batch basis. On request, optical anti-reflection coatings for other wavelengths are also available according to customer requirements.
You are free to specify the dimensions! Our company specializes in the rapid production and delivery of optics with individual sizes. We can quote, manufacture, and deliver custom-sized optics as fast, as fixed-dimensions can usually ship. Often this is of great advantage because the optics perfectly fit into your application without any necessary modifications.

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 want to supply. It is essential to specify the refraction index of the lens material as well as the exact lens 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.
All given details and specifications are mean reference values and are not guaranteed. Also, please consider our "Notes on specifications".
