ABSTRACT:
The present invention relates to an optical scanning device that comprises a light source to emit a beam of light, and a beam splitter to split that beam into several beamlets, and further a first objective lens to direct said beamlets onto a focal plane wherein each of said beamlets impinges on the focal plane spacially separated from each other, wherein the beam splitter comprises several birefringent elements for splitting said beam, preferably a stack of Wollaston prisms.
