    This problem is overcome by milling a sample chamber with a focused ion beam. Figure 14 shows a FIB milled pit (114 × 108 × 65 μm) that was cut within 114 hours (FEI FIB200, Ga-source, 30 kV, 11500 pA). The smooth floor produced by FIB milling provides excellent observation of the contained sample using a transmitted light microscope.
