Claim:
1. A viewing device for a stereo projection system comprising: a first viewing window; and a second viewing window, the first and second viewing window each having an optically filtering filter layer system, wherein the first and second viewing window each have a filter spectrum in the visual spectral range with a plurality of pass bands that are separated from each other by blocking regions, 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, wherein each filter layer system is designed as an absorption filter layer system having a plurality of substances absorbing in differing spectral ranges, wherein a first one of the absorbing substances is a cyanine dye in the supramolecular configuration of a J-aggregate, and wherein a second one of the absorbing substances is a rhodamine or squaraine dye.
