Laminated glazing
A laminated glazing includes a first glass layer, a second glass layer, and a third layer between the first glass layer and the second glass layer. The third layer has an optical property that differs in a first region as compared to a second region, the first region being within five inches of one side of the laminated glazing and the second region extending from the first region toward another side of the laminated glazing.
1. A laminated glazing, comprising:
a first glass layer;
a second glass layer; and
an optical coating layer that has multiple sublayers between the first glass layer and the second glass layer, the optical coating layer having more of the sublayers in a first region than in a second region, wherein the optical coating layer includes a texture formed on a surface of the optical coating layer that abuts a surface of the second glass layer.
2. The laminated glazing of claim 1 , wherein the optical coating layer includes an optical coating material that has a concentration that is greater in the first region than in the second region.
3. The laminated glazing of claim 1 , wherein the sublayers include at least a first sublayer that is formed from a first optical coating material and a second sublayer that is formed from a second optical coating material that is different from the first optical coating material.
4. The laminated glazing of claim 1 , wherein the first region is an outer region, and the second region is a central region.
5. The laminated glazing of claim 1 , wherein the first region is within five inches of one side of the laminated glazing and the second region extends from the first region toward another side of the laminated glazing.
6. The laminated glazing of claim 1 , wherein the first glass layer and the second glass layer have substantially the same index of refraction.
7. The laminated glazing of claim 4 , wherein the texture is rougher in the first region than in the second region.
8. A laminated glazing, comprising:
a first glass layer;
a second glass layer; and
an interlayer between the first glass layer and the second glass layer, the interlayer having a texture that provides diffuse reflectance,
wherein the diffuse reflectance of the interlayer reduces in a gradual manner moving inward from an outer periphery of the laminated glazing.
9. The laminated glazing of claim 8 , wherein the texture is rougher near the outer periphery of the laminated glazing and gradually becomes smoother moving inward from the outer periphery to gradually reduce the diffuse reflectance moving inward from the outer periphery of the laminated glazing.
10. The laminated glazing of claim 8 , wherein the diffuse reflectance varies in a gradual stepped manner with multiple stepped changes between locations of the laminated glazing.
11. The laminated glazing of claim 8 , wherein the diffuse reflectance varies in a gradient manner between locations of the laminated glazing.
12. The laminated glazing of claim 8 , wherein the interlayer includes an optical coating material that defines an optical property.
13. The laminated glazing of claim 12 , wherein the optical coating material has a concentration that is greater in a first region than in a second region.
14. The laminated glazing of claim 13 , wherein the concentration of the optical coating material is zero in the second region.
15. The laminated glazing of claim 8 , wherein the diffuse reflectance of the interlayer reduces in a gradient manner moving inward from the outer periphery of the laminated glazing.
16. A laminated glazing, comprising:
a first glass layer;
a second glass layer; and
an optical coating layer that restricts optical transmittance between the first glass layer and the second glass layer,
wherein the optical transmittance of the optical coating layer varies in a gradual stepped manner with multiple stepped changes between locations of the laminated glazing.
17. The laminated glazing of claim 16 , wherein the optical transmittance increases moving inward from an outer periphery of the laminated glazing.
18. The laminated glazing of claim 16 , wherein the optical transmittance is defined by a texture formed on a surface of the optical coating layer.
19. The laminated glazing of claim 18 , wherein the texture is rougher in a first region of the optical coating layer than in a second region of the optical coating layer, the first region being within five inches of one side of the laminated glazing and the second region extending from the first region toward another side of the laminated glazing.
20. The laminated glazing of claim 19 , wherein the surface of the optical coating layer is smooth in the second region.
