    摘要: In an optical assembly having a light source which provides two optically different light components with essentially planar wavefronts on an optical axis, wherein the light components differ at least in their wavelength; in the case of an objective lens which projects the two optically different light components into a projection space; and in the case of an optical component which is arranged on the optical axis and has an plane through which the wavefronts of the two light components pass and in which at least two different areas of the optical component with different dispersion behaviors n(λ) abut against one another in the lateral direction with respect to the optical axis; the optical component causes phase shifts of the wavefronts of the two light components, wherein the phase shift of the wavefronts of the one light component differs by at least one quarter of the wavelength of that light component between the two different areas, and wherein the phase shift of the wavefronts of the other light component does not differ between the two different areas, such that an intensity distribution of the one light component in the projection space by interference with itself differs from an intensity distribution of the other light component in the projection space.
