Abstract: A thin glass article is provided that has a first face, a second face, one or more edges joining the first and second faces, and a thickness between the first and second faces, where the faces and the one or more edges together form an outer surface of the thin glass article. The thin glass article has an ion-exchanged surface layer on its outer surface. The ion-exchanged surface layer is non-uniform, wherein the non-uniform ion-exchanged surface layer has an associated compressive surface stress which varies between a minimum and a maximum value over the outer surface and/or a depth of layer which varies between a minimum and a maximum value over the outer surface. A method for producing a thin glass article and a use of a thin glass article are also provided.

Abstract: An optical arrangement for a camera module with an image sensor is provided. The optical arrangement includes optical components having a transparent cover element; an infrared absorbing cut-off filter; and an optical lens. The optical components are arranged, along an incident optical beam path going through the optical components onto the image sensor, in a sequence through the transparent cover element, then the infrared absorbing cut-off filter, and then the optical lens.
