It is capable of measuring the difference in lattice spacing between specimens of high-quality float-zone silicon to Δd/d ≈ 6 × 10-9. It has recently undergone a thorough update of its control systems and mechanics. These upgrades result in the ability to collect data with improved stability, less settling time of the instrument, and less operator intervention.The Review of scientific instrumentsThe NIST silicon lattice comparator upgrade.PMC105940649999-NISTHenins ACline JPSzabo CIMendenhall MHfalseThe NIST silicon lattice comparator upgrade.The NIST silicon lattice comparator has been in service, in various forms, since the 1970s.
