Abstract
At least one composite workpiece includes: a substrate body including at least one first surface and at least one second surface, the at least one first surface of the substrate body being shaped convexly at least in areas and the at least one second surface of the substrate body being shaped concavely at least in areas, and the at least one composite workpiece has a bow with an absolute value of between 0.1 μm and 50 μm due to the curved shape of the at least one first surface and the at least one second surface; and at least one first coating, at least the at least one first surface of the substrate body being coated at least in areas with the first coating.

At least one composite workpiece, comprising:
- a substrate body comprising at least one first surface and at least one second surface, the at least one first surface of the substrate body being shaped convexly at least in areas and the at least one second surface of the substrate body being shaped concavely at least in areas, and the at least one composite workpiece has a bow with an absolute value of between 0.1 μm and 50 μm due to the curved shape of the at least one first surface and the at least one second surface;
- and
- at least one first coating, at least the at least one first surface of the substrate body being coated at least in areas with the first coating.
A method of manufacturing a composite workpiece, the composite workpiece comprising a substrate body comprising:
- at least one first surface and at least one second surface, the at least one first surface of the substrate body being shaped convexly at least in areas and the at least one second surface of the substrate body being shaped concavely at least in areas, and the at least one composite workpiece has a bow with an absolute value of between 0.1 μm and 50 μm due to the curved shape of the at least one first surface and the at least one second surface;
- and at least one first coating, at least the at least one first surface of the substrate body being coated at least in areas with the first coating, the method comprising:
- providing the substrate body;
- applying a coating onto a surface of the substrate body;
- and
- maintaining a substrate temperature at less than or equal to 200° C. at least temporarily or continuously during the application of the coating onto the surface of the substrate body.
Augmented reality glasses, comprising:
- at least one composite workpiece comprising:
- a substrate body comprising at least one first surface and at least one second surface, the at least one first surface of the substrate body being shaped convexly at least in areas and the at least one second surface of the substrate body being shaped concavely at least in areas, and the at least one composite workpiece has a bow with an absolute value of between 0.1 μm and 50 μm due to the curved shape of the at least one first surface and the at least one second surface;
- and
- at least one first coating, at least the at least one first surface of the substrate body being coated at least in areas with the first coating.
