Greater magnification is possible because electron waves are shorter than light waves. Highest magnification requires shortest possible electron waves, hence higher voltage. The portable models sacrifice extreme magnification, but R.C.A. gives 5,000 diameters, G.E. 10,000 (compared to 2,000 useful upper limit in the best microscopes using light waves). Both can be "blown up" photographically to give in effect 100,000 diameters or more. The G.E. instrument, developed by Dr. Simon Ramo and Dr. Charles H. Bachman, has a horizontal system, is 52 inches high, operates on a 110-volt light circuit, The R.C.A. model, only 16 inches...
