The invention includes a hybrid lens with a fixed focal length, which includes five lenses. The lens is suitable for use in a LIDAR measuring system. In addition, the use of a biaspherical plastic lens is proposed for correcting image field opacity and/or astigmatism and/or for mapping an image object.
