Abstract
An optical device includes a substrate having a surface, a peripheral edge, an area of vision, and a boundary portion of the surface between the peripheral edge and the area of vision. At least a portion of the boundary portion is textured. A coating is applied to the surface of the substrate over the area of vision and the textured boundary portion. In some embodiments, the substrate is comprised of a polymeric material and the coating is comprised of multiple layers of dielectric material and the substrate is textured such that the textured portion increases adhesion and the durability of the dielectric coating.
Claims23
An optical device comprising:
- a substrate having a surface, a peripheral edge, an area of vision, and a boundary portion on a portion of the surface between the peripheral edge and the area of vision, at least a portion of the boundary portion being textured;
