Abstract: The invention relates to an illumination filter (36, 44) for an illumination filter system (2) for medical imaging, in particular multispectral fluorescence imaging, as performed e.g. in a microscope (1) or endoscope, in particular a multispectral fluorescence microscope. The present invention provides an illumination filter for medical imaging, in particular a multispectral fluorescence imaging, that is capable of capturing simultaneously more than one fluorescence signal, and allow a homogeneous illumination for obtaining different images from the object illuminated by comprising a spatial filter pattern (43) masking a defined filtering fraction of a first illumination path (47) on the filter and masking a defined filtering fraction of a second illumination path (48, 49, 50) on the filter, wherein the filtering fraction of the first and the second illumination paths (47, 48, 49, 50) are different.
