Abstract
An apparatus and method for creating an aperture between the lenslets of a lenslet array, which lenslet array has been produced by a process that leaves at least partially opaque barriers between the lenslets, comprising utilizing a photoresist over the entire surface of the lenslets and the spaces therebetween and shining ultraviolet light from the back of the array so that light exposes the photoresist in the lenslet portions and not in the areas therebetween.
