Diaphragm device
A diaphragm device with which individual wavelengths or ranges of wavelengths in the path of a beam of spectrally dispersed light can be suppressed. Such a diaphragm device comprises at least one array of diaphragms, wherein the individual diaphragms of the array are arranged in a definite relation to each other and may be coupled in the path of the beam and each diaphragm of the array in the coupled state is arranged in a given relation to an individual wavelength or a range of wavelengths.
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 individual diaphragms,
wherein the individual diaphragms of the at least one array are arranged along a predetermined direction in a mutually defined relation with respect to each other, and wherein the array of at least two individual diaphragms is positioned in a fixed manner in the predetermined direction and the individual diaphragms of the array are coupled in the path of the beam, 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,
wherein the individual diaphragms in the array are arranged in the path of the beam and the diaphragms comprise adjustable optical shutters.
2. The diaphragm device according to claim 1 , wherein the optical shutter comprises Liquid Crystal Displays or Digital Micro-Devices.
