ANTI-REFLECTIVE LENSES AND METHODS FOR MANUFACTURING THE SAME

摘要

The invention relates to a method of applying an anti-reflective coating to an optical surface of a mold. In one embodiment, the method includes the steps of providing a lens mold having an optical surface; forming a layer of a super hydrophobic material over the optical surface, where the super hydrophobic material contains an amount of dipodal silane that is a relative percentage of the super hydrophobic material; forming an anti-reflective coating layered structure over the layer of the super hydrophobic material; and forming a layer of a coupling agent deposited with a monolayer thickness to the anti-reflective coating layered structure using vapor deposition under aprotic conditions or by dip coating or spin coating using a solution of a coupling agent in an aprotic solvent.

1. A method for applying an anti-reflective coating to an optical surface of a mold, comprising the steps of:
(a) providing a lens mold having an optical surface; (b) forming a layer of a super hydrophobic material over the optical surface, by heating a thermal boat that is in contact with one or more crucibles containing the super hydrophobic material to a temperature between about 200° C. and about 500° C., wherein the super hydrophobic material contains an amount of dipodal silane that is a relative percentage of the super hydrophobic material; (c) forming an anti-reflective coating layered structure over the layer of the super hydrophobic material; and (d) forming a layer of a coupling agent deposited with a monolayer thickness to the anti-reflective coating layered structure using vapor deposition under aprotic conditions or by dip coating or spin coating using a solution of a coupling agent in an aprotic solvent.
