Disclosed are an array and a method for the spectrally resolving detection
of a sample (22) that is illuminated by means of an illuminating
radiation (12) by detecting a sample radiation (24) emitted by the sample
(22). Said array comprises an illuminating beam path via which
illuminating radiation (12) can be delivered to the sample (22) from a
lighting source (10, 10'), and an observation beam path via which sample
radiation (24) can be delivered to a detector (40) an observation
radiation. An interferometer (30) that is disposed in a section of the
observation beam path, which does not comprise the sample (22), splits
incident input inteferometer radiation into two portions by means of an
interferometer beam splitter, directs said two radiation portions via two
paths which are provided with radiation-guiding means (34, 36) and whose
effective path length difference can be modified, and superimposes the
two radiation portions in a mutually interfering manner so as to form an
interferometer output radiation such that the spectral distribution of
the observation radiation (24) impinging at a specific point of the
detector (40) can be modified by modifying the effective path length
difference. The interferometer (30) is arranged in a beam path section
that is common to the illuminating beam path and the observation beam
path such that the effective path length difference in the illuminating
beam path changes when the effective path length difference is modified
in the observation beam path.
