Abstract:
1. An anamorphic objective for imaging an object onto an image acquisition unit, comprising: at least one first plane of symmetry and at least one second plane of symmetry, wherein the first plane of symmetry is oriented perpendicular to the second plane of symmetry; at least one first objective section and at least one second objective section, wherein, from the object to be imaged in a direction of the image acquisition unit, the first objective section is firstly arranged followed by the second objective section; a diaphragm arranged between the first objective section and the second objective section; at least one first anamorphic optical element arranged in the first objective section; and at least one second anamorphic optical element arranged in the second objective section, wherein the anamorphic objective fulfills the following conditions: wherein wherein the first anamorphic optical element, which is arranged in the first objective section, has a first refractive power in the first plane of symmetry and a second refractive power in the second plane of symmetry, and wherein the first refractive power and the second refractive power have different signs.
