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 introduced which has significant advantages for fast imaging.As part of Prior Scientific, Queensgate have developed longer-range stages providing significant advantages for image acquisition using multiphoton microscopy. Piecewise adaptive linearity compensation will improve linearization for longer range (400 µm to 800 µm) multi-axis stages (XY and XYZ) and stages with local linearity errors.Improved linearization will extend the use of the long-range multi-axis stage to surface imaging applications which require sub-nanometre resolutions and reduce image distortion. This has application in life science, semiconductor wafer testing and manufacture and has potential for quantum photonics.

Queensgate在高速、高精度应用方面拥有独特的控制能力。超低噪声电子器件允许在更高的带宽下工作;超过40%的级谐振频率，低皮米分辨率。加速和减速控制可实现最快的步进稳定时间，最近引入了速度控制，这对快速成像具有显著优势。作为Prior Scientific的一部分，Queensgate开发了更长距离的载物台，为使用多光子显微镜进行图像采集提供了显著优势。分段自适应线性补偿将改善长距离（400 µm至800 µm）多轴工作台（XY和XYZ）和具有局部线性误差的工作台的线性化。改进的线性化将把长距离多轴工作台的使用扩展到需要亚纳米分辨率的表面成像应用中，并减少图像失真。这在生命科学、半导体晶片测试和制造中具有应用，并且具有量子光子学的潜力。
