Applied Multilayers offers a solution for fingerprints and other handling marks on high quality optical coatings, especially high performance antireflection coatings used on consumer products such as spectacle lenses or display windows used on mobile phones. According to the company, water, grease and skin oils are easily removed with the swipe of a cloth by adding a hydrophobic topcoat to the AR coating stack. Although the topcoat, contained in a “pill” which is released onto the substrate by thermal evaporation, is typically only about 10nm in thickness it is designed to be very durable and the hydrophobic effect is still measurable even after the typical product life cycle of two years.
