Paper Abstract

By combining an aspherical reflector and a thick lens at its center, it is possible to produce an ultra wide-angle optic called the GEM. The device was originally conceived as means for broadcasting optical signals over nearly a full angular sphere. Since the fabrication and testing of several GEMs, wide angle receiving and imaging functions have also been evaluated.
