As part of a course in Optical Metrology and Instrumentation, our year 1 research students attend a week residential hosted by The Centre for Precision Technologies (CPT) at the University of Huddersfield.  This provided access to industry grade instrumentation as well as specialist guidance from experts at Huddersfield and the National Physics Laboratory (NPL). 

The overall objectives of this event were to better understand the importance of metrology in an industrial context, develop a greater understanding of measurement accuracy and uncertainties, and work as a team to develop and use optical instruments capable of measurements on a sub-micron scale.

Highlights included an introduction to ‘surface parameters’ by Prof. Liam Blunt, where participants found out about the different ways of describing engineering surfaces, and the importance of getting this right in a fascinating range of applications ranging from jet engines and formula one intercoolers to hip replacement joints!  Industrial measurement techniques, and training on a range of specialist facilities including focus variation profilers and electron beam microscopes was offered by Huddersfield’s in-house Metrology Engineer, Oliver Armitage.  We also welcomed Daniel O’Connor, Science Lead at NPL, who provided an insight into standards and traceability from a perspective of the UK’s National Physics Laboratory.

Lab work focussed on building, characterising and using a benchtop microscope capable of measuring surface profiles with sub micrometre accuracy.  Working in teams, the team assembled the optical systems, performed alignment and tested several target samples.  Part of the challenge involved analysing the data, using software written by the student teams.

Outside of the lab, students were able to enjoy visiting Huddersfield.  Teams explored the city, and the surrounding hills, and made good use of the local climbing centre!
