Abstract
Planck is a European Space Agency (ESA) satellite, launched in May 2009, which will map the cosmic microwave background
anisotropies in intensity and polarisation with unprecedented detail and sensitivity. It will also provide full-sky maps of astrophysical
foregrounds. An accurate knowledge of the telescope beam patterns is an essential element for a correct analysis of the acquired
astrophysical data.We present a detailed description of the optical design of the High Frequency Instrument (HFI) together with some
of the optical performances measured during the calibration campaigns.We report on the evolution of the knowledge of the pre-launch
HFI beam patterns when coupled to ideal telescope elements, and on their significance for the HFI data analysis procedure.
