Filter arrangement for a wavelength division multiplex stereo system and stereo glasses, stereo projector or stereo display of a wavelength division multiplex stereo system

The invention relates to a filter assembly 30 for a wavelength division multiplex stereo system 10. This is provided with at least a first sheet-shaped filter 31 having at least one narrow band transmission or block area and represents an interference filter 31. Furthermore, a second layer shaped filter 32 according to the invention is at least provided, which is connected flat to the first layer-shaped filter 31 and the filter dye is a 32nd The second sheet-shaped filter 32 has in this case at least one transmission or block or absorption portion which in its position corresponds to that of the at least one narrow band transmission or block portion of the first sheet-shaped filter 31st Preferably, all transmission or block or absorption regions correspond. Furthermore, the invention relates to a stereoscopic glasses 20, a stereo viewer 12, or a stereo display, which are each provided with at least two inventive filter arrangements 30, wherein the narrow-band transmission or block or absorption ranges of these filter assemblies 30 do not have a mutual overlap. With this invention, an efficient and convenient implementation of a Wellenlangenmultipex stereo system 10 is possible.
