Patent ID: 8858099

Claim:
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: f T ′ f W ′ = AF and s T ′ = s W ′ wherein f′ T is the focal length of the anamorphic objective with respect to the first plane of symmetry, f′ W is the focal length of the anamorphic objective with respect to the second plane of symmetry, wherein f′ T is greater than f′ W , AF is a predetermined anamorphic factor, s′ T is a first distance between the second objective section and the image acquisition unit in the first plane of symmetry, and s′ W is a second distance between the second objective section and the image acquisition unit in the second plane of symmetry, 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.
