The (220) lattice spacing of a silicon crystal was measured by combined x-ray and optical interferometry to about 3 x 10(-8) relative accuracy. The value obtained is d220 = 192015.551 +/- 0.005 fm. After correcting for the impurity-induced lattice contraction, d220 = 192 015.569 +/- 0.006 fm is obtained.
