Abstract

An optical device includes a substrate and a coating applied to the substrate, wherein the optical device has a first side exposed to an environment and a second side that is unexposed.

First claim

We claim:

1. An optical device, comprising:
a substrate having a first side positioned toward an environment and a second side positioned toward another device;
an antireflective coating including NbTiO x applied to the first side of the substrate;
an electrical conducting coating applied to the second side of the substrate; and
a glare reducing coating applied to the electrical conducting coating;
wherein the optical device has a first side exposed to the environment and a second side that does not face the environment.

2. The optical device of claim 1 , wherein the substrate includes plastics, synthetic sapphire, glass and synthetic diamond.

3. The optical device of claim 1 , wherein the optical device includes two or more substrates.

4. The optical device of claim 3 , wherein the two or more substrates are a laminate.

5. The optical device of claim 1 , further comprising a protectant coating.

6. The optical device of claim 5 , wherein the protectant coating is applied to the antireflective coating.

7. The optical device of claim 5 , wherein the protectant coating is a fluorinated alkyl ether polymer having a functionalized silane.

8. The optical device of claim 1 , further comprising a bandpass filter.

9. The optical device of claim 8 , wherein the bandpass filter is applied to glare reducing coating.

10. The optical device of claim 1 , wherein a second anti-reflective coating is applied to the glare reducing coating.

11. The optical device of claim 1 , wherein the anti-reflective coating is a stack including a first plurality of dielectric layers having a first refractive index interleaved with at least a second plurality of dielectric layers having a second refractive index.

12. The optical device of claim 1 , wherein the anti-reflective coating is a dielectric stack of a first layer of NbTiO x , a first layer of Sift, a second layer of NbTiO x , and a second layer of SiO 2 .

13. The optical device of claim 1 , wherein the electrical conducting coating includes indium tin oxide, nano-based transparent composites, or optically transparent conductors.

14. The optical device of claim 1 , wherein the electrical conducting coating is transparent at a wavelength of light between 850 nm to 2000 nm.

15. The optical device of claim 1 , wherein the glare reducing coating is a multilayer circular polarizer including a linear polarizer combined with a quarter wave optical retarder.
