Anti-Reflection Coatings

High-quality AR-coated glasses

ARC Series

Special Properties

  • Coating efficiently reduces surface reflections
  • Significantly increased transmission for visible wavelengths compared to uncoated glasses
  • No formation of ghost images, phantom light or double laser beams when light passes through
  • The refractive index of the coating is adapted to both, the surrounding medium, and the substrate
  • All-dielectric metal-free multi-layer coating
  • Very low light absorption
  • High abrasion resistance
  • Excellent coating adhesion

Typical Applications

  • Anti-reflection coating for optical windows and lenses
  • Non-reflective sensor cover glasses
  • Medical equipment
  • Laser windows
  • Coating for optical measuring instruments
  • Automotive cockpits
  • Camera protection windows
  • Robotics applications
  • Anti-reflection coatings for single lenses and lens assemblies

We created our ARC coating series to offer excellent anti-reflection properties and high optical light transmission in the visible wavelength range. Our ARC-coatings are vacuum-deposited multi-layer dielectric thin-film coatings whose layers adapt the refractive index of the substrate to the ambient medium's refractive index. With this coating design, we reduce reflections to a minimum.

The surfaces of uncoated glasses show a typical reflection of approximately 4,25% per side, so they reflect about 8,5% of light in the visible wavelength spectrum. 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.


Furthermore, our ARC anti-reflection coatings effectively suppress unwanted secondary reflections, often overlaying a transmitted image with a weak identical image and making it appear blurry. By using our ARC coating, the image remains sharp, brighter and keeps significantly better contrast. The image quality is maintained, and almost no light gets lost. When used as laser windows, our ARC coating suppresses double laser beams, and the available laser power increases because practically no light is reflected and, therefore, almost entirely transmitted.

The layers of our double-side ARC and single-side ARC-1S coating are applied to selected high-quality iron-reduced float glasses by a vacuum deposition process. For the ARC-B series, we use inspected BOROFLOAT® substrates. We adapt the refractive index of the 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 on this website. On request, we also coat other substrate materials or finished optics, and we can adapt the refractive index of our anti-reflection coatings to the respective carrier material. We also have the capabilities to coat optical lenses and other optics provided by the customer with our anti-reflection coatings on a per batch basis. On request, optical anti-reflection coatings for different wavelengths are also available according to customer requirements.

 

How do I get a quotation? Are there fixed standard dimensions?

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 off-the-shelf usually ship. Often this is of great advantage because the optics perfectly fit into the application without any necessary modifications.

In case you need your batch of optical lenses custom 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 precise lens dimensions and focal length. The lenses to be coated must not already have a coating layer. Please let us know the maximum allowed amount of light that still might be reflected by the coated lens surface (residual reflection), inform us about the relevant wavelength range, and let us know which light source you use.
