A high resolution optical scanner is disclosed for scanning a light beam onto a receiving medium. The scanner includes a light source for generating a light beam, optical means for anamorphically shaping the beam, and a rotatable polygon for moving the light beam through a predetermined scan angle. In order to obtain high resolution throughout a scan line, a mirror, having power in the tangential plane and in the sagittal plane, is positioned to intercept the beam from the polygon and direct it to the receiving medium.
