Calibration By Interferometry

Interferometry is the highest level of accuracy for length measurement. Offering a unique rapid turnaround service for interferometry calibrations, Avon-Dynamic Calibration are proudly one of only a few UK based laboratories offering UKAS (ISO17025) calibration of gauge blocks by Interferometry (Class A), long series gauge blocks and length bars.

Our Interferometry services are conducted at our purpose-built BS EN ISO/IEC 17025 accredited calibration and testing laboratory. The scope of our Interferometry services includes gauge blocks, long series gauge blocks, length bars, length bar accessories, optical flats and optical parallels. Our services cover tungsten carbide, steel and ceramic equipment. We will communicate with you if the equipment needs any extra repair or replacement services, but our in-house team will deliver on turnaround time and make sure your equipment is ready to be used again.
