digital pathology scanner lighting unit and digital pathology scanner

摘要

The present invention relates to digital pathology and in particular to a digital pathology digitizer lighting unit. In order to provide digital illumination scanning with enhanced illumination, a digital pathology digitizer lighting unit (10) comprising a light source (12), a light mixing chamber (14) and a light diffuser is provided. (16). The light source comprises a plurality of light elements (18) which are disposed longitudinally along a linearly extending direction. the mixing chamber comprises a transparent volume (22) providing a mixing distance (dm) between the plurality of the light elements and the light diffuser such that a light of uniform intensity is provided at a downstream edge ( 26) 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. In addition, the light diffuser comprises a diffusion material such that light is transformed into light having uniformity at different angles, particularly at low angles.
