New Tool Simplifies Polishing on Optical Lenses

Without silicon there would be no computer industry since most computer chips consist of this semiconductor material. The same is true for solar cells: They too are predominantly silicon-based. The monocrystals are cut in round slices approximately one millimeter thick, which experts call wafers. Their surfaces must be as smooth as glass; irregularities may only be a few nanometers wide, i.e. less than one ten thousandth of a hair. Therefore, after they have been cut out of a large silicon monocrystal, the wafers must be ground and polished.
