Abstract
The present invention relates to a security element for protecting valuable articles, having a first and a second authenticating feature. The first authenticating feature comprises a first arrangement having a plurality of focusing elements present in a first grid, and a second arrangement having a plurality of microscopic structures present in a second grid. Here, the first and second arrangement are disposed in such a way that the microscopic structures of the second arrangement are seen magnified when viewed through the focusing elements of the first arrangement. The second authenticating feature is machine and/or visually verifiable and is not influenced by the first arrangement of the first authenticating feature.
