Endoscopic and/or exoscopic imaging device for spectral imaging, and method for the operation thereof

A surgical imaging device for spectral imaging, in particular multispectral imaging and/or hyperspectral, imaging for an, the surgical imaging device including at least one shaft;

• at least one imaging channel arranged at least partly in the shaft the imaging channel having at least one first imaging branch which includes at least one first spectrally selective beam splitter which spectrally selectively splits an optical image representation of an original spectral range into at least one first spectral partial image representation of a first spectral range and at least one further first spectral partial image representation of a further first spectral range, wherein the first spectral range is different from the further first spectral range;
• wherein the first imaging branch further includes a first image sensor, at least for capturing the first spectral partial image representation-PO, and at least one first relay optical unit for relaying the further first partial image representation, the imaging device comprising:
• at least one second spectrally selective beam splitter disposed within the at least one second imagining branch of the imaging channel, the at least second spectrally selective beam splitter spectrally selectively splits the further first partial image representation of the further first spectral range into at least one second spectral partial image representation of a second spectral range and at least one further second spectral partial image representation of a further second spectral range, wherein the second spectral range is different from the further second spectral range and;
• wherein the second imaging branch further includes at least one second image sensor for capturing the second spectral partial image representation, and at least one second relay optical unit, for relaying the further second partial image representation, wherein the first relay optical unit of the first imaging branch and the second relay optical unit of the second imaging branch are arranged one behind the other such that an image plane of the first relay optical unit is identical to an object plane of the second relay optical unit.
