Abstract:
1. An apparatus for the spectral selection and detection of spectral regions of a light beam, the apparatus comprising: a first selection unit including a first spectral splitting device configured to spectrally split the light beam; and a first device configured to deflect a portion of the spectrally split light beam so as to provide a deflected first spectral region in first and second beam paths and an undeflected second spectral region; and a first detection unit including a plurality of first detectors, at least a first one of the first detectors being disposed in the first beam path of the spectral region, at least a second one of the first detectors being disposed in the second beam path of the first spectral region, each of the first and second first detectors having a respective different detection property or using a respective different detection method, and each of the first and second first detectors including at least one of:
