Abstract
Hard coatings are applied to a lens assembly. In an embodiment, the coated lens assembly (140) includes a first layer (106B) including siloxane; a second layer (106A) including siloxane, wherein the second layer has opposing sides and a hardness greater than the first layer; and a third layer (104) including an amorphous carbon selected from a diamond-like carbon and a diamond-like nano-composite. The first layer (106B) and third layer (104) are positioned on opposing sides of the second layer (106A). The third layer (104) has a hardness greater than the second layer (106A).
Claims20
A coating for a substrate comprising:
- a siloxane layer comprising a siloxane-organic interpenetrating network and having a thickness of at least about 20 microns;
- and
- a diamond-like nano-composite layer comprising an amorphous carbon and a siloxane, wherein the first layer and third layer are positioned on opposing sides of the second layer, and the third layer has a hardness greater than a hardness of the siloxane layer.
