We have determined the polarized reflectance spectra Rua, Rib and R~c of the high temperature superconductor Bi2Sr2CaCu208 in the normal state. The photon energy was varied between 30 meV and 6 eV. By fitting a Lorentz-Drude model or by performing a Kramers-Kronig analysis, respectively, the spectra
