Abstract
The present invention relates to digital pathology, and relates in particular to a digital pathology scanner illumination unit. In order to provide digital pathology scanning with improved illumination, a digital pathology scanner illumination unit () is provided that comprises a light source (), a light mixing chamber (), and a light diffuser (). The light source comprises a plurality of light elements () that are arranged longitudinally along a linear extension direction. The mixing chamber comprises a transparent volume () providing a mixing distance (DM) between the plurality of the light elements and the light diffuser such that light with a uniform intensity is provided at a downstream edge () of the mixing chamber; and the mixing chamber is arranged, in terms of light propagation, between the plurality of the light elements and the light diffuser. Further, the light diffuser comprises a diffusing material such that the light is transformed into light that has uniformity at different angles, in particular low angles.
