Nanometer

A measure of length equal to one one-billionth of a meter. In other words, a nanometer is .000000001 meters. Nanometers are important in the semiconductor industry.

This uncertainty in measurement is only a couple of picometers' worth but is extremely important for scientists who need very precise measurements.

Uncertainty at a grand scale: Heisenberg's principle observed in macroscopic objects

For step heights, measurement uncertainties in the subnanometer range - and for measurements of the mean structure spacing on extensive lattice standards even in the range of 10 picometers - have been achieved and confirmed in comparison with optical diffraction measurements.The new measuring instrument is available for dimensional precision measurements with nm resolution on 3D micro and nano structures such as micro gears, micro balls, hardness indenters and nano lattice standards as well as for comparisons of measures; moreover, it serves as a platform for research and development tasks.

The unit provides eight calibration references between 1297 nm and 1306 nm and 12 references between 1531 nm and 1550 nm, each with a stability of a few picometers. NIST scientists are now investigating methods to incorporate calibration references in the 850 nm region.

The ICP/OES delivers high resolution with < 5 picometers for the UV range and < 10 picom-eters for the visible range, all due to its optical design, which integrates a high density holographic grating and 1-m focal length optics.

With positioning accuracies better than 60 picometers (0.06 nm) in X, Y, and Z, these nanopositioning sensors are, according to Asylum Research, the quietest available on an AFM.
