Detection arrangement for an optical scanning microscope and optical scanning microscope

A detection arrangement for an optical scanning microscope, the detection arrangement comprising

• a beam splitter configured to:
• receive descanned detection light,
• split the detection light into a first part and a second part,
• direct the first part of the detection light into a first beam path, and
• direct the second part of the detection light into a second beam path;
• a first dispersive element disposed in the first beam path and configured to spectrally separate the first part of the detection light along a first spectral separation direction;
• a first array detector disposed in the first beam path and configured to receive the spectrally separated first part of the detection light;
• a second dispersive element disposed in the second beam path and configured to spectrally separate the second part of the detection light along a second spectral separation direction;
• and
• a second array detector disposed along the second beam path and configured to receive the spectrally separated second part of the detection light;
• wherein the beam splitter, the first dispersive element, and the second dispersive element are configured such that a first reference direction corresponding to the first spectral separation direction imaged back via the first beam path to a plane arranged before the beam splitter and a second reference direction corresponding to the second spectral separation direction imaged back via the second beam path to the plane arranged before the beam splitter are different from each other.
