ABSTRACT:
A laser beam is focused as a cone whose apex is to be located on the surface of a part to be treated. A reference distance between the surface and a given point of the focusing element is determined, at which the apex is located on the surface. The actual distance between the surface and the given point is measured and the difference between the actual distance and the reference distance is determined. The focusing element is displaced so that the difference determined is cancelled.
