ABSTRACT:
An electronic device of the invention includes a tip emitter formed in a well that is defined in a substrate. An extractor disposed about the well extracts emissions from the tip emitter. A wide lens focuses the emissions through its opening. The opening is sufficiently large and spaced far enough away to encompass the majority of a divergence angle of the emissions. The emissions are focused into a spot.
