Abstract
According to one aspect of the present invention, there is provided an anamorphic objective lens having optical elements arranged along an optical axis in a sequence from an object side to an image side, the optical elements including: a first objective section arranged on the object side; a second objective section arranged on the image side; and a diaphragm arranged between the first and second objective sections, wherein the second objective section includes at least one astigmatizer.
Claims26
An anamorphic objective lens comprising optical elements arranged along an optical axis in a sequence from an object side to an image side, the optical elements comprising:
- a first objective section arranged on the object side;
- a second objective section arranged on the image side;
- and
- a diaphragm disposed between the first and second objective sections,
- wherein the second objective section comprises at least one astigmatizer for modifying or reducing or eliminating astigmatic imaging effects.
An anamorphic objective lens having optical elements arranged along an optical axis in a sequence from an object side to an image side, the optical elements comprising:
- a first objective section arranged on the object side;
- a second objective section arranged on the image side;
- a diaphragm arranged between the first and second objective sections;
- an adjustable focusing device, in particular a focusing device arranged in the first objective section and movable relative to the second objective section;
- and
- at least one astigmatizer for modifying or reducing or eliminating astigmatic imaging effects and which, during operation of the anamorphic objective lens, is fixed with respect to the second objective section, in particular with respect to the optical elements of the second objective section.
A method for adjusting an anamorphic objective lens, the method comprising:
- one or more assembly steps before putting the lens into operation, in which the optical elements of the lens are mounted (310), in which the astigmatizer is first mounted and then adjusted (320) to modify or reduce or eliminate astigmatic imaging effects, and in which the astigmatizer and/or the elements of the astigmatizer are fixed (330) after the adjustment is completed.
