Abstract: A viewing device for a stereo projection system, having a first and a second viewing window, each having an optically filtering filter layer system, wherein each viewing window has a filter spectrum in the visual spectral range having a plurality of pass bands that are separated from each other by blocking regions, and wherein each pass band of the filter spectrum of the first viewing window is covered by an associated blocking region of the filter spectrum of the second viewing window. Each filter layer system can be designed as an absorption filter layer system having a plurality of substances absorbing in differing spectral ranges, wherein at least one of the absorbing substances is a cyanine dye in the supramolecular configuration of a J-aggregate.

Abstract: The invention relates to the field of 3D cinema projection using wavelength-division multiplexing. Three-dimensional color images are generated and viewed using a filter pair. Respectively differently pre-specified regions of the visible spectrum are filtered out by the two filters of the filter pair such that a plurality of delimited spectral intervals are transmitted in the blue, green and red domain of color perception. Here, the position of the transmitting intervals for the two perspective partial images is different. The respectively filtered-out regions are produced by absorption bands. The absorption bands here can be generated by a plurality of different colorants in the filter material. The filters can, for example, be disposed in glasses for viewing three-dimensional color images with two viewing openings for the eyes of an observer.
