Abstract: A structured polarizer (linear polarizing filter) with side-by-side in a plane (lateral) regions having different polarization directions, complete extinction and complete transparency, is presented with two superpositioned planes (polarizers) with a polarizer whose surface can be structured. The polarization properties of a plane is structured in such a way and the planes are mutually oriented in such a way that polarizing regions with different polarization directions and/or polarization properties, such as contrast, polarization-direction-dependent absorption properties as a function of the wavelength, and/or non-polarizing regions, such as transparent or opaque and/or regions having a predefined absorption for specified wavelengths are obtained.
