Imaging optical system

The present invention provides an imaging optical system. An imaging optical system according to an embodiment of the present invention includes a plurality of lenses arranged side by side from the object side to the image side. The lenses can zoom a first area of an object side image of the lens closest to the image side in the lens with respect to an object side image of the lens closest to theobject side in the lens and compress a second area of an image side image of the lens closest to the image side in the lens with respect to an object side image of the lens closest to the object sidein the lens. The object side surfaces and the image side surfaces of the plurality of lenses, respectively, may have a conic constant not equal to zero. 本发明提供种摄像光学系统。根据本发明的实施例的摄像光学系统包括从物体侧到像侧并排布置的多个透镜，并且所述多个透镜可以将所述多个透镜中的最靠近像侧的透镜的像侧图像的第区域相比于所述多个透镜中的最靠近物体侧的透镜的物体侧图像而扩大，并将所述多个透镜中的最靠近像侧的透镜的像侧图像的第二区域相比于所述多个透镜中的最靠近物体侧的透镜的物体侧图像而压缩，而且所述多个透镜分别的物体侧表面和像侧表面可以具有不等于零的圆锥常数。
