In most fields of engineering, working to micrometre accuracy is considered to be the standard, with typical high-quality bearings having tolerances within hundreds or even tens of microns. But pioneers working in nanopositioning are now operating at tens of picometres – a million times smaller. For comparison, an atom is around one to five-hundred picometres in diameter, and a human hair is 100,000,000 picometres across.
Queensgate Instruments specialize in creating nano positioning and sensing solutions for high-technology industries, with variants suitable for precision measurement in UHV, radiation environments and cryogenic temperatures.
Over the decades, Queensgate Instruments has undertaken various one-off space-borne projects as subcontractor and in collaboration with companies working for NASA and ESA.
