Nanostructured antireflection coatings: AR-plas^® and AR-plas2

Broadband antireflection coatings, universally applicable for quartz, glass, and plastics

The patented AR-plas^® and AR-plas2 processes combine thin vapor-deposited layers with nanostructured layers. The very low effective refractive indices of the nanostructures allow perfect transitions to the air refractive index. Very wide spectral ranges and high angles of incidence can be addressed. The technology is particularly suitable for serial coating of optical parts with a size of a few millimeters up to 25 centimeters.

Our range of services

• Optimized antireflection coatings according to customer specifications for broad spectral ranges (300 nm to 2500 nm) and light incidence angle ranges (0° to 75°) for any substrate materials (including plastics, glass and quartz)
• Antireflection coatings of sample parts and small series made of polymers such as PMMA, PC, OKP, Zeonex, EP-8000, Apel, and many others
• Realization of other surface functions:
  • Superhydrophobic or superhydrophilic (antifog properties).
  • Black with high absorption
  • Electrically conductive/antistatic
• Licensing of the patented AR-plas^® and AR-plas2 technologies
• Surface and layer characterizations, in particular the precise measurement of reflection from curved surfaces

Details about our technology AR-plas^® and the further development AR-plas2

AR-plas^®

• The structure formation in the AR-plas® process takes place by self-organization in an organic material (polymer or vaporized organic compound) using plasma etching in vacuum. It is advantageous to carry out the process with an industry-standard plasma IAD equipment, which allows the simultaneous treatment of large quantities. The functionalized surfaces are mechanically sensitive and therefore particularly suitable for protected areas.

AR-plas2

• The further development of this technology offers lowest reflectance from UV to near IR and shows excellent resistance in climatic tests. Extreme light incidence angles and polarization neutrality can also be addressed. The process combines inorganic thin films and nanostructures. The layers are largely free of organic components.
