Beschreibung
Zusammenfassung:	Method for treating antireflection coatings on an optical substrate (17) involves a stage for carrying out the physical vacuum-deposit of a fluorinated polymer-containing layer having a low refractive index and is characterized in that the stage includes in deposing a silicium or magnesium fluoride/fluorinated polymer hybrid layer (21d) by simultaneous vacuum evaporation of silicium or magnesium fluoride and the fluorinated polymer, In a preferred embodiment, the fluorinated polymer is embodied in the form of a polymer or tetrafluorethylen polymer and the components are evaporated by a Joule effect or by electron bombardment. The method is advantageously used for improving the adherence of a low refractive index layer to a subjacent layer of a pile of antireflection coatings which is deposited on any optical substrate or the inventive substrate. The substrate produced by the method and a device for carrying out the method are also disclosed.
