We demonstrate a novel method of scanning super high resolution images using a broad band light source and a conventional microscope. We experimentally and through simulations show that this is accomplished through a near-focusing mechanism by utilizing self assembled lenses. We will provide bright- and dark-field, and fluorescence modes results that show resolution below 100 nm and magnifications between 2 and 7 times.  Interestingly, the emission intensity of fluorescent nano-particles with diameters ~ 90-240 nm was found to increase between 2-10 times when compared to their intensity without self-assembled lenses. The throughput rate of the capturing images enhanced many times with an array of lenses. The proposed method is easy to accomplish, inexpensive, highly reproducible, and provide a way of achieving super-spatial resolution in a far-field mode without any changes in the hardware and software of the microscope.
