发明名称 Security element for protecting valuable objects, e.g. documents, includes focusing components for enlarging views of microscopic structures as one of two authenication features
摘要 In a security element (A) having first and second authenication features (AF's), the first AF consists of focusing components and microscopic structures, arranged in first and second rasters respectively and placed such that the microstructures appear enlarged when viewed through the focusing components. The second AF is mechanically and/or visually examinable, and not influenced by the focusing component arrangement of the first AF. An independent claim is included for the production of (A), by forming the first AF by combining the focusing component and microscopic structure arrangements, then combining the second AF with at least one second AF.
