Abstract: Lens assemblies according to the disclosure include an anamorphic lens component and a primary lens component. The anamorphic lens component includes cylindrical lens elements and one or more spherical lens elements disposed between the cylindrical lens elements and translatable along an optical axis of the anamorphic lens assembly with respect to the cylindrical lens elements. Optical characteristics of the anamorphic lens component are adjustable as the one or more spherical lens elements translate along the optical axis such that the cylindrical lens elements and the one or more spherical lens elements in combination produce a first astigmatism that is opposite to a second astigmatism produced by unequal movement of an image plane along horizontal and vertical axes as an object moves from infinity focus toward the lens assembly.

Abstract: Anamorphic lens assembly having first and second anamorphic lens components, each having an astigmatism at infinity focus that is greater than an astigmatism at close focus. As the anamorphic lens assembly transitions from infinity focus to close focus, the astigmatism decreases for both of the first and second anamorphic lens components, which allows for proper focusing at close focus (when the object is close to the lens assembly). The astigmatism of the first anamorphic lens component may be equal and opposite to the astigmatism of the second anamorphic lens component, such that the astigmatisms of the anamorphic lens components cancel out one another.
