Abstract:
A laser focussing arrangement comprising a focussing mirror (M1) with a curved surface arranged on a carrier which is displaceable in one plane, and having a spherical reflecting surface, characterized in that the displaceable carrier is formed by a rocking member (10) which is at least approximately z-shaped when seen in top view, the rocking member having a rocking longitudinal arm (27) which is articulately connected on both ends to transverse arms (25, 26), the longitudinal arm carrying the focussing mirror (M1), in that the transverse arms (25, 26) are arranged so as to be pivotable about pivot axes perpendicular to the plane of displacement, and in that the center of curvature (M) of the spherical reflecting surface (43) of the focussing mirror (M1) lies at least substantially on an axis extending through the geometric center of the longitudinal arm (27), perpendicular to the plane of displacement.
