Abstract
An optical scanning device for the production of cartesian images with the aid of heat rays, comprising a rotatable refractive polygon (2) with plane parallel surfaces (2a, 2b), the central axis (3) of the polygon (2) being inclined by a polygon inclination angle ( beta ) relative to its rotational axis (6), and the inclination angle ( beta ) being selected in dependence on the inclined setting of the plane parallel surfaces (2a, 2b) in such a manner as to provide compensation of the astigmatism in image production by the polygon. Instead of an inclined setting of the polygon, an aspherical mirror may be provided in the ray path, the mirror having a curvature so matched to the optical characteristics of the polygon as to compensate for the astigmatism (see Fig. 2 not shown). <IMAGE>
