ABSTRACT:
A microlens array having first and second sets of spherically-shaped microlenses. The second set of spherically-shaped microlenses are located in the areas between individual microlenses of the first set in such a way that there is minimized gapping over the entire microlens array. A semiconductor-based imager includes a pixel array having embedded pixel cells, each with a photosensor, and a microlens array having spherically-shaped microlenses as just described.
