A multitude of unique properties characterizes the oleophobic optical anti-reflection coating of our ARC-O 
series. Both sides of the high-quality substrate glass are coated with an anti-reflection coating optimized for visible light. On the surface of the operator side, there is a durable and resistant oleophobic coating with an anti-fingerprint effect, which also repels liquids and dirt.
Conventional anti-reflective coated display glasses increases the contrast of a display by minimizing the reflection of the glass surfaces and maximizing the light transmission. However, as soon as a user touches a non-reflective screen, fingerprints leave visible marks on the anti-reflective coating. This disturbing effect on image reproduction and aesthetics is a well-known problem, especially with touch displays in public spaces. The single side oleophobic and double-sided anti-reflection coating of the ARC-O series offers an optimal solution for such applications because it reduces the visibility of fingerprints by up to 90%. The adhesion of dirt and liquids is also much less than with conventional anti-reflective coated glasses.
The oil and liquid repellent coating is extremely durable and resists hundreds of thousands of friction cycles in the MIL-C 675C abrasion test. Hence, it can easily be cleaned with a soft, dry cloth. The broadband and high light transmission supported by the high-quality iron-reduced selected white float substrate glass of the ARC-O coating ensures an almost loss-free, excellent imaging quality.
