Abstract
A plan apochromat corrected microscope objective including multiple subsystems with optical components and/or component groups, wherein an optical component or a component group can move axially in the interior of the microscope objective. The axially movable component or the component group includes a concave-convex lens or lens group oriented toward the object plane, with a form factor of: wherein X is the form factor, cis the curvature of the surface oriented in the direction of the object plane, and cis the curvature of the surface oriented in the direction of the image plane, of the axially movable lens or lens group, X lying within a range from −8<X<−1.
