Abstract
The present invention relates to an illumination filter system (2) for medical imaging, in particular multispectral fluorescence imaging, as performed e.g. in a microscope (1) or endoscope, such as a surgical microscope, in particular a surgical multispectral fluorescence microscope, comprising a first optical filter (35). The present invention also relates to an observation system (3) for medical imaging, in particular multispectral fluorescence imaging, as performed e.g. in a microscope (1) or endoscope, in particular a multispectral fluorescence microscope, comprising a beam splitter (21) adapted to split a light image (13) into a first light portion (16, 17) along a first light path (18) and a second light portion (20) along a second light path (19). To improve known illumination filter systems and observation systems, so these systems work with one light source only, are capable of capturing simultaneously at least one fluorescence signal and a signal of visible reflected light and allow a homogeneous illumination for obtaining different images from the object illuminated, the first optical filter (36) is adapted to quench light of at least one fluorescence excitation band wit…
