Patent ID: 7158295

Claim:
An apparatus for determining directional transport processes with a scanning microscope comprising: a deflection means for coupling an illuminating light beam into a first multi-focus generating device; a scanning module for scanning the illuminating light beam across a specimen and for graphical display of the specimen on a peripheral device; the first multi-focus generating device for generating at least a first and a second non-parallel illuminating light beams propagating toward a rotation point in the scanning module, wherein the multi-focus generating device is disposed between the deflection means and the scanning module, and the rotation point defined as a point of intersection of the first and the second non-parallel illuminating light beams, the rotation point being located in a focal plane of an optical system of the scanning microscope, and the first non-parallel illuminating light beams defining a first focus in the specimen, the second non-parallel illuminating light beams defining a second focus in the specimen, the first and the second foci being disposed in a plane of the specimen; and wherein the multi-focus generating device comprises a dichroic beam splitter that splits the illuminating light beam into the first and the second non-parallel illuminating light beams, and a displaceable and/or pivotable deflection mirror serves to deflect the first or the second non-parallel illuminating light beam.
