The brightness of the solar F-corona along the ecliptic is calculated in the visual and near-IR spectral range, and the results are discussed with respect to future observations. It is shown that dust particles close to the sun have a strong influence on the corona brightness, which enables their investigation by remote sensing experiments. Comparison of model calculations with the observations indicates that the zodiacal dust cloud remains mainly undisturbed up to the beginning of a dust-free zone that amounts to about 5 solar radii. Calculations of visual brightness and polarization indicate a change of particle properties for a solar distance smaller than 20, which has to be proven by future experiments. The IR F-corona brightness has contributions from solar radiation scattered at dust particles up to wavelengths of 5 microns. The superposition with the thermal emission of particles produces a significant feature at the edge of the dust-free zone but the existence of an additional dust ring cannot be supported. The observational data at 10 microns are found to be in contradiction to the present study.
