Title (EN) MICROSTRUCTURED SAPPHIRE SUBSTRATES
(FR) SUBSTRATS EN SAPHIR MICROSTRUCTURÉS
Abstract:
(EN) The present invention relates to sapphire substrates having anti-fouling properties, to methods for their preparation and to their use as optical components in devices which transmit or receive light. The sapphire substrates have a micropatterned surface which comprises a plurality of sapphire pillars which project from the surface. The pillars have an aspect ratio less than or equal to about 1.0, and the ratio of the spacing between adjacent pillars to the pillar height is greater than or equal to about 0.5.
(FR) La présente invention concerne des substrats en saphir ayant des propriétés anti-salissures, leurs procédés de préparation et leur utilisation à titre de composants optiques dans des dispositifs qui émettent ou reçoivent de la lumière. Les substrats en saphir ont une surface comportant des micromotifs sous forme d'une pluralité de piliers en saphir qui font saillie par rapport à la surface. Les piliers ont un rapport d'aspect inférieur ou égal à environ 1,0, et le rapport de l'espacement entre des piliers adjacents à la hauteur de pilier est supérieur ou égal à environ 0,5.
