Nano-imaging through metallic nanostructures has recently attracted lost of attention with the proposals of superlens and nanolens. The difficulties, however, are in achieving color images and magnification for the practical observation of the image. We propose a nanolens, which is made of silver nanorods arranged in stacked layered configuration that provides broad resonance for achieving color imaging, as well as it provides long-distance image transfer without significant loss. A tapered arrangement of the nanorods within the stacked layers enables magnification of image for its far field observation by usual optics.
