1. An immersion mixture, comprising:
a plurality of components, wherein at least two of the components have optical refractive powers different from one another, and the immersion mixture possesses an optical refractive power resulting from the respective proportions of the components,
wherein one of the components is a water-insoluble compound and a further component is a solvent suitable for dissolution or mixing of the water-insoluble compound,
wherein the water-insoluble compound is a fluorinated organic compound,
wherein the solvent suitable for dissolution or mixing of the water-insoluble compound comprises diethylacetoacetamide or malondialdehyde bis(dimethylacetal).
