Abstract
The invention relates to a method of applying an anti-reflective coating to an optical surface of a mold, including providing a lens mold having an optical surface, forming a deposition layer of a fluoride or oxide material to the optical surface of the lens mold, forming a layer of a hydrophobic material over the deposition layer, wherein the hydrophobic material contains an amount of dipodal silane that is a relative percentage of the hydrophobic material, forming a first layer of SiOwith a thickness of 5-40 nm over the layer of the hydrophobic material, forming an anti-reflective coating layered structure over the first layer of SiO, and forming a layer of a silane coupling agent that is deposited with a monolayer thickness to the anti-reflective coating layered structure using vapor deposition under aprotic conditions or by dip coating using a solution of silane coupling agent in an aprotic solvent.
