摘要

"Structure of grade micro optics, method for producing the same, and product containing one or several visual effects, holographic or corresponding.The invention relates to a grid structure (g) micro optics formed on a substrate (s) that is preferably produced as a structure of grid surface.The invention relates also to a method for producing the above structure of grid.In addition, the invention refers to a product that comprises one or several areas of pattern (a, B, C, d)The areas of unique pattern are formed by means of the grid structure according to the invention.According to the invention,The grid structure (g) is arranged to produce a visual effect to an observer holographic or diffraction of light by corresponding based on guidance from the light difratada from ESTVourself of grade and corresponding to the wavelength of the project (sym) substantially to only a few orders of diffraction (m).The order of diffraction only thus corresponds to a certain direction of observation of the visual effect observed on the mentioned wavelength of the project.According to the invention, the grid structure is arranged to leave a free range of angles between adjacent directions of observation.So that the grid structure (g) is examined and directions corresponding to the mentioned range of angles produces, to the observer, a clearly observable effect based on the diffraction.The above structure of grid and thus substantially transparent.The invention is suitable to produce visual effects that are transparent in the way described above, but, at the same time, clearly visible in the directions of observation, for example,On the transparent substrates such as these.
