    Patent number: 6631020
    Abstract: The focal distance (f) of a laser (1) beam (2) is adjusted by projecting the beam (2) onto the center of a mirror (3) of variable curvature and controlled by a depression circuit or by electrostatic forces. Thus the focus (4) can be displaced in a direction which is inaccessible to the usual means such as turning but rigid mirrors.
