Analysis of introducing aperiodicity in microlens arrays in a superlens-based magnifier for an improvement in resolution

Microlens arrays (MLAs) have tiny lenses with a diameter less than a millimetre, typically placed in a periodic arrangement. A compact magnifier using two layers of MLAs has been demonstrated by us. In this project, we intend to increase the resolving power of the MLA magnifier by adjusting the periodicity of the microlenses, which would minimize the spherical aberration of the MLA magnifier. In a sense, this would be analogous to making the lens curvature aspheric in singlet lenses. In this project, the optimal adjustment of the microlens periodicity which will result in the highest improvement in the resolution of the MLA magnifier will be investigated.
