Prior Scientific (Queensgate)

Prior Scientific

Queensgate Instruments was founded in 1979 and spun out of the ground breaking research in nanomotion at Imperial College in London. The company defined new levels of accuracy and performance in nanopositioning systems. Queensgate’s early research and product developments proved to the world that it could play a major part in the research and development in various industries requiring the highest precision.

 

Queensgate founders wrote ‘The Nanopositioning Book’ which defined the world of Nanopositioning.
