The completion of Webb’s mirror polishing is the most challenging and important technological milestone in the manufacture of the telescope. The mirrors were polished at L-3 Integrated Optical Systems – Tinsley to accuracies of less than one millionth of an inch. That accuracy is important for forming the sharpest images when the mirrors cool to -400*F (-240*C) in the deep cold of space.
