2results about How to "Guaranteed optical properties" patented technology

The present application can provide an optical modulation device, an optical device including the same, or a manufacturing method, which can stably maintain designed optical characteristics even after a packaging process in which pressure is applied, such as an autoclave process. The present application can also provide an optical modulation device, an optical device including the same, or a manufacturing method, which can stably maintain an orientation state of an optical modulation layer while effectively securing adhesion between an upper substrate and a lower substrate.

The present application provides a structure capable of easily imparting a hydrophobic function while maintaining the optical properties of a sensor device, and easily replacing the sensor device. A structure 100 mounted to the outer surface of a sensor device 400 having a curved surface shape on the outer surface includes a substrate 101, and a fine concavo-convex structure layer provided on both surfaces of the substrate 101, the fine concavo-convex structure layer having a first fine concavo-convex structure layer 102 on the side of the sensor device 400, and a second fine concavo-convex structure layer 103 on the side opposite to the side of the sensor device 400, the second fine concavo-convex structure layer 103 having hydrophobicity, the structure 100 having a three-dimensional shape following the curved surface shape of the outer surface.
