Optical article and method for producing the same
A method for producing an optical article. A first layer that is light-transmissive is formed on an optical substrate directly or with an additional layer in between. A silicide material, light-transmissive thin film is formed on the surface of the first layer.
1. A method for producing an optical article, comprising:
forming a first layer that is light-transmissive on an optical substrate directly or with an additional layer in between, and
forming a light-transmissive thin film containing silicide on a surface of the first layer to provide an antistatic function and/or an electromagnetic wave shielding function,
wherein the first layer is included in an inorganic or organic antireflection layer.
2. A method for producing an optical article according to claim 1 , wherein forming the light-transmissive thin film containing silicide includes depositing silicon and metal on the surface of the first layer.
3. A method for producing an optical article according to claim 1 , wherein forming the light-transmissive thin film containing silicide includes depositing a transition metal silicide on the surface of the first layer.
4. A method for producing an optical article according to claim 1 , wherein:
the first layer contains metal oxide, and
forming the light-transmissive thin film containing silicide includes implanting silicon into the surface of the first layer.
5. A method for producing an optical article according to claim 2 , further comprising forming an antifouling layer on the light-transmissive thin film containing silicide directly or with an additional layer in between.
6. An optical article comprising:
an optical substrate,
a first layer that is light-transmissive and formed on the optical substrate directly or with an additional layer in between, and
a light-transmissive thin film containing silicide formed on a surface of the first layer to provide an antistatic function and/or an electromagnetic wave shielding function,
wherein the first layer is included in an inorganic or organic antireflection layer.
7. An optical article according to claim 6 , wherein the antireflection layer has a multilayer structure, and the antireflection layer includes the first layer and the light-transmissive thin film containing silicide.
8. An optical article according to claim 7 , further comprising an antifouling layer formed on the light-transmissive thin film containing silicide directly or with an additional layer in between.
9. An optical article according to claim 6 , wherein the optical substrate is a plastic lens substrate.
10. An optical article according to claim 9 , wherein the optical article is a spectacle lens.
11. A pair of spectacles comprising:
the spectacle lens of claim 10 , and
a frame having mounted thereto the spectacle lens.
12. A system comprising:
the optical article according to claim 6 , and
an image-forming apparatus for projecting an image through the optical article.
13. A system comprising:
the optical article according to claim 6 , and
an imaging apparatus for capturing an image through the optical article.
14. A system comprising:
the optical article according to claim 6 , and
a medium that allows access through the optical article.
