The invention relates to an apparatus for transmitted light illumination for light microscopes, in particular stereo microscopes or macroscopes. The apparatus has a light source for emitting an illuminating light beam, and a holding device for holding a sample to be examined, wherein a deflection device is provided between the light source and the holding device for contrast adjustment, wherein an angle distribution of the illuminating light bundle relative to an optical axis can be varied with the deflection device. The apparatus is characterized in that the deflection device comprises a prism film. The invention also relates to a method for transmitted light illumination for light microscopes and a microscope system. |
