Abstract
An F-theta objective is provided that has five individual lenses with a first individual lens as biconcave lens with a focal length, a second individual lens as meniscus with a focal length, a third individual lens as meniscus with a focal length, a fourth individual lens as a biconvex lens with a focal length and a fifth individual lens as a plano-convex lens with a focal length and a total focal length f of the F-theta objective. A ratio between the focal lengths to the total focal length satisfies predetermined conditions.
