Patent ID: 7675617

Claim:
An optical array for the spectrally selective identification of light of a light beam, comprising optics for the spatial spectral decomposition of the light beam; a selector for selecting a predeterminable continuous spectral range of the decomposed light beam; a detector for detecting light from the selected spectral range of the decomposed light beam; at least one blocking element which can be introduced into the light beam prior to the detector, in order to mask out a predeterminable spectral subrange lying within the selected continuous spectral range; and wherein the position of the at least one blocking element in the light beam can be altered; wherein the at least one blocking element is embodied in tiltable fashion; wherein the at least one blocking element is embodied as a thin web; wherein the at least one blocking element is mirror-coated; and further comprising a photodetector, onto which wavelength components masked out by the at least one blocking element can be reflected.
