Half of them are concerned with the concept of low beta (small source size/ high divergence). This survey is an opto-mechanical review with all of the thermal/high heat-load issues on optics. This plan uses new package, OASYS aimed at making X-ray beam simulations for most optical parameters. White beam aspects are introduced, using ANSYS and COMSOL modules, leading to beam propagation FEA analysis with deformed optics. This presentation describes the optical aspects of the ESRF beamlines (high/low beta optics), and their transition towards this new source. Some key issues like IDs beam illumination; power filtering and optimization of the best part of the spectrum are detailed. Mirrors and monochromator crystals deformation will be presented, first for the day-one best conditions. As a second issue, OASYS enables to simulate the full beamline, from the IDs to the experiment, allowing simulating virtual experiments, with samples. This work is developed through many ESRF contributors; first the OASYS designers, Optics group, and then opto-mechanical experts, in association with mechanical engineering.
