Disclosed is an optical array (2) for the spectrally selective identification of light of a light beam, particularly for identifying light of a detecting light beam (3) in a preferably confocal scanning microscope (1). Said optical array comprises a means (18) for the spatial spectral decomposition of the light beam, means for selecting a given continuous spectral range, and a detector (28). The inventive optical array (2) is characterized by at least one blocking element (25, 26, 27) which can be introduced into the light beam in order to stop down a given partial spectral region located within the selected continuous spectral range.
