Claim 0:
1. An atomic layer deposition method for coating an optical lens with a magnesium fluoride layer, the method comprising:
(i) exposing an optical lens to a precursor gas comprising magnesium, thereby forming a magnesium-containing precursor layer over a surface of the lens;
(ii) exposing the magnesium-containing precursor layer to a first oxygen-containing gas, thereby forming a magnesium oxide layer;
(iii) exposing the magnesium oxide layer to a source gas comprising fluorine, thereby forming an intermediate layer comprising magnesium and fluoride; and
(iv) exposing the intermediate layer to a second oxygen-containing gas, thereby forming a magnesium fluoride layer.
