Abstract:
1. A diaphragm device with which individual wavelengths or ranges of wavelengths in the path of a beam of spectrally dispersed light can be suppressed, the diaphragm device comprising: at least one array of at least two diaphragms, wherein the individual diaphragms of the at least one array are arranged in a mutually defined relation with respect to each other so that they may be coupled in the path of the beam, wherein the diaphragms of the at least one array include diaphragm screens, and wherein the surface areas of the diaphragm screens in the path of the beam pointing to the direction of the incidence of light are one of light absorbing and light reflecting; and means for arranging each diaphragm of the at least one array, in the coupled state, in a given relation to an individual wavelength or a range of wavelengths.
