Abstract
An optical flat bed scanning system, particularly useable in a typesetter, has an optical device to linearize beam deflection positions in a planar deflection plane with essentially two elements. The optical device comprises an aplanatic unit lens with an approximately planar surface and a spherically convex surface and a field flattening mirror with a spherical reflecting surface.
