• Sensor Technology

Our ARC multi layer broadband antireflection coating (BBAR-coatings) can be coated on any suitable glass substrate material. The highly efficient multilayer antireflection coating system decreases surface reflection losses, while significantly increasing the light transmission. Unwanted secondary reflections that are interfering with the transmitted light or that might cause ghost images are almost completely eliminated by our ARC anti reflection coating. The total reflection of uncoated glass of about 8%, can be minimized by our ARC antireflection coated glass to a value even below 0,2% per side in partial ranges of the visible spectrum. Compared to a common BBAR coating with a total rest reflection of for example 2%, this is a significant and visible improvement. The ARC antireflection coating can be modified or optimized for other wavelengths, single lines and even for lower rest reflections.
