摘要
A contrasting process and device allows a relief contrast to be obtained for microscopic amplitude and/or phase objects. The input aperture (L') of the condenser (2) is partially and asymmetrically masked at the same time as an image (S') of a sector diaphragm (S) is generated in the output aperture (L") of the objective lens (3), a phase segment (8) of a phase plate (7) covering the image (S') at least partially. The size of the phase segment (8) may be adapted to the size of the image (S') cutout; it may however also be substantially smaller. In the latter case, the sector diaphragm (5) may have additional attenuating sectors (D) made of semi-transparent material with a defined attenuating factor, for example 15 %. The process and device are suitable for transmitted light and/or reflected light microscopy in a normal or inversed beam path.
