Smaller Worlds – John Andrew Clarke of Queensgate Instruments looks at the shrinking world of nanopositioning

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 […]

The incredible world of nano positioning

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. Positioning control With data and processing demands increasing year on year, there is a constant drive to make technology ever smaller. This presents new challenges for manufacture and inspection […]

Meeting the demands of positioning and sensing in UVAC environments

UVAC versions of the Queensgate Series NanoSensors and our DPT-D and DPT-E ranges of Digital Piezo Actuators are widely used in Synchrotrons and Beamline applications. NX/NZ NanoSensors The NX/NZ non-contact position measuring systems are based on the principle of capacitance micrometry with superior resolution and stability performance.

Subnanometre positioning in a vacuum – the NC Nanosensor capacitive sensor series

The NC NanosensorTM capacitive sensor series, has been specially developed to meet the requirements of partial accelerators. The NCG-1-AL-UHV Capacitive Sensors are the longest range sensors in the Queensgate range. Designed for high resolution positioning in harsh environments. The NanoSensors are non-heating and maintain their zero position when powered down. Originally developed for magnet positioning inside vacuum, it offers […]

Astronomy and space science nanopositioning solutions

Space and space challenges 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. These included precision capacitance micrometers used in the “force
moment sensor”, part of the robot-arm mechanisms used on the International Space Station and the Space Shuttle.
The capacitive sensing systems […]

The National Physical Laboratory (NPL) – Testing nanopositioning devices for Queensgate

The National Physical Laboratory (NPL) has a long standing collaboration with Queensgate Instruments in the area of provision of metrology for nanopositioning. NPL and Queensgate recently completed an Innovate UK project in which NPL developed optical interferometry to enable Queensgate to verify the performance of the next generation of its nanopositioning stages. Queensgate’s nanopositioning devices […]
