Survey Of The Collective French Effort On X-Ray Multi Layered Optics

In this overview we emphasise the present effort on multilayers studies in France. Several French laboratories have coordinated a research program in view to develop the different technologies now used to prepare multilayered optics.This program takes into account the needs to overcome the constraints of the grazing incidence X-UV optics for the synchrotron source users, plasmas physicists and astrophysicists.
