  • Patent number: 4684808
    Abstract: A scanning lens system for a particle beam scanning device having deflection elements and optical lenses for corpuscular radiation characterized by the deflecting elements being deflecting dipole elements which are disposed in the particle beam directly preceding at least one imaging lens so that the deflection chromatic aberration for arbitrary deflection angles should disappear and the lens field of a magnetic projection lens should be free of magnetic deflection elements. As a result of the arrangement, the isotropic deflection chromatic aberrations of the dynamically deflecting dipole elements compensates the isotropic off-axis chromatic aberrations of at least one imaging lens and at least one imaging lens forms an image rotation-free system.
