(AR-coated glass)
A multitude of unique properties characterize the oleophobic optical anti-reflection coating of our ARC-O 
series. Both sides of the high-quality substrate glass have an anti-reflection coating optimized for visible light. Moreover, there is a durable and resistant oleophobic coating on the operator's side surface with an anti-fingerprint effect, which also repels liquids and dirt.
Conventional anti-reflective coated display glasses increase the contrast of a display by minimizing the glass surfaces' reflection 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-sided oleophobic and double-sided anti-reflection coatings of the ARC-O series offer an optimal solution for such applications. The oleophobic coating reduces fingerprint visibility on the user's side 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 highly durable and resists hundreds of thousands of friction cycles in the MIL–C–675C abrasion test. Hence, cleaning is easy with a soft, dry cloth. The broadband and high light transmission supported by the high-quality selected float substrate glass of the ARC-O coating ensure excellent imaging quality.
