Abstract (en)
[origin: WO2008012200A2] The present invention relates to an optical filter unit with an entrance and an exit and a wave-modulating element arranged between entrance and exit. In order to provide an optical filter unit in which at least one characteristic of the wave-modulating element is influenced less strongly during the passage through the filter unit, the invention proposes that a compensation element which compensates at least partially for at least one characteristic of the wave-modulating element is provided in the optical direction between the wave-modulating element and exit.
