Advanced scanning patterns have advantages for techniques such as AFM as they increase the scanning speed and enable movement without abrupt changes in velocity, however high precision positioning during the scanning is also required. Other applications such as nanolithography, semiconductor testing and photonics use advanced scanning patterns and require...

Prior Scientific are looking for an innovative solution to develop Queensgate control for Z/tip/tilt and tip/tilt nanopositioning stages and effective strategies for calibration. The project proposed will require further development of the NPL nanopositioning test rig using a combination of interferometers and autocollimators to measure angular displaceme...

Prior Scientific are looking for an innovative solution which allows Queensgate nanopositioning stages to continue to meet the increasing demands for semiconductor, hard disc testing and atomic force microscopy which are anticipated to routinely require low-picometre accuracies. The project proposed will develop and test higher-order automatic linearity c...

Queensgate have unique control capability with expertise in high speed, high precision applications. Ultra-low noise electronics allow operation at higher bandwidths; over 40% of the stage resonant frequency with low picometre resolutions. Control of acceleration and deceleration enables the fastest step settle times, and recently velocity control was int...
