Abstract

A device is described for two- dimensional scanning with the aid of a pivotable plane mirror 4 and a rotatable mirror drum 3. By including a correction element 5 between the plane mirror 4 and the image plane bo of an objective system 1 and by ensuring that the axis of rotation r of the plane mirror 4 passes substantially through the centre of curvature of the image plane bo, a satisfactory correction is obtained both for the image plane curvature as a result of the rotating mirror drum 3 and the image plane curvature as a result of the pivotable plane mirror 4. <IMAGE>
