Device for the spectral selection and detection of the spectral regions of a light beam

摘要

An apparatus for the spectral selection and detection of spectral regions of a light beam includes a selection unit and a detection unit. The selection unit includes a spectral splitting device and a light blocking and reflecting device. The spectral splitting device is for spectrally splitting the light beam. The light blocking and reflecting device is for blocking a first spectral region and reflecting at least part of an unblocked second spectral region. The detection unit includes a number of detectors. At least one of the detectors is disposed in a first beam path of the blocked second spectral region. At least one of the detectors is disposed in a second beam path of the reflected first spectral region. Each of the detectors has a different detection property or uses a respective different detection method.
