An anamorphic zoom lens is designed for altering the size and aspect ratio of a laser beam. The design is based on using a Galilean beam expander in which the optical elements consist of two rotating cylinders. The rotation of the cylinders allows the spherical and cylindrical powers of the rotating cylindrical lens to be altered in such a manner that the magnification is anamorphic. A simple anamorphic zoom lens based on rotating cylindrical lenses is designed and then implemented. Operation of the anamorphic lens demonstrates a 1 to 1 to 10 to 1 aspect ratio beam conversion.
变形变焦透镜被设计用于改变激光束的尺寸和纵横比。该设计基于使用伽利略扩束器，其中光学元件由两个旋转圆柱体组成。圆柱体的旋转使得旋转柱面透镜的球面和柱面光焦度得以改变，从而使放大率呈现变形特性。设计并实现了一种基于旋转柱面透镜的简单变形变焦透镜。该变形透镜的操作展示了1:1到10:1的纵横比光束转换。
