Classification: CPC C  G  B | IPC B  C  G

Claim 8:
9. An optical element, comprising:
an optical surface comprising zinc sulfide;
a coating comprising a bifunctional molecule arranged on the optical surface, the bifunctional molecule comprising a first functional group and a second functional group, the first functional group forming a disulfide bond to the zinc sulfide of the optical surface, and the second functional group being a phenyl group;
a hydrophobic hybridized carbon material non-covalently bonded to the phenyl group of the bifunctional molecule of the coating; and
an encapsulation layer arranged on the hydrophobic hybridized carbon material;
wherein the hydrophobic hybridized carbon material is non-covalently bonded to the phenyl group of the bifunctional molecule of the coating by Pi stacking interactions; and
wherein the hydrophobic hybridized carbon material is non-covalently bonded to the second functional group and is indirectly bonded to the zinc sulfide of the optical surface.
