    • For this throughput calculation a total of six reflections were assumed in the MET system, including the mask, the two MET camera optics, and a condenser/illuminator assembly with three elements. Since there was no definite MET condenser design available when this paper was prepared, the choice of number of condenser elements is somewhat arbitrary, but realistic
