ABSTRACT:
For distributing the flux density of an input light flow (11), this input light flow is split-up in at least two light flows (12, 13) comprising different cross-sectional parts of the input light flow (11), and an output light flow (15) is output to which two partial flows each comprising a flux density fraction of at least one of the light flows (12, 13) are superimposed in one direction by means of a partial reflection at a partially reflecting optical surface (9). Additionally, at least one further output light flow (17) is output to which two further partial flows each comprising further flux density fractions of the same light flows (12, 13) as in case of the first output light flow (15) are superimposed in a further direction by means of the same partial reflection at the partially reflecting optical surface (9).
