Dimensional
Dimensional Metrology at NPL encompasses provision of national measurement standards for dimensional metrology using a variety of techniques including optical and contact measurement, as well as supply of measurement services, instruments and facilities, contract research, consultancy, training and knowledge transfer.
Dimensional research

-
NPL is the home of the frequency-stabilised lasers that provide the practical realisation of the metre within the UK. These lasers have a very stable vacuum wavelength (i.e. a very stable frequency) that is obtained by controlling the frequency to that of an atomic or molecular absorption.
-
NPL is currently engaged in research to improve metrology at the nano metre level which builds on a number of instruments previously developed at NPL which were designed for measuring surface texture and form with traceability to the metre.
Dimensional case studies
-
NPL has developed a range of non-contact dimensional standards with sub-micron accuracies for calibrating vision inspection machines.
-
NPL can now measure the thermal performance of pipe insulation helping toward energy efficient building construction.
-
A new device to make non-contact, pain free measurements of leg ulcers.
