Nano-optical elements – a new breakthrough direction in security technology. Electron beam origination technology is used in the production of originals of the nano-optical elements. The technology is well protected against counterfeiting or imitation by both the high price of e-beam equipment and the complexity of the technology. E-beam technology provides a wide range of security features for visual control. The effect is easy for verification: from a normal viewing position an observer sees one image, but after rotation of an element through 180 degrees, an observer sees a different image in the same place. Initially nano-optical elements have to be calculated in Fresnel approach. After that the nano-structures are recorded by using electron beam lithography. The security feature is well protected against counterfeiting by the 10 nanometers accuracy of the microrelief fabrication. Breakthrough technology for automatic verification of CLR (Covert LaserReadable) images has also been developed.
