Queensgate: Leading Performance Nanopositioning For Microscopy

By Simon Bush, Prior Scientific

Queensgate, a brand of Prior Scientific, has a prolific 40-year history in the design of nanopositioning instruments and sensors, having supplied technology used in the manufacture of the majority of the world’s hard disks and on the international space station. Since joining the Prior Scientific group, they have turned part of their attention to the field of microscopy, and are now pleased to announce the launch of the OP400 objective positioner and NanoScan SP nanopositioning stage range.

The Best Step-Settle and Positioning Performance
High throughput screening and analysis are mainstays of biological and materials science imaging. For this reason, the OP400 and SP range are designed with speed in mind, offering rapid full-range travel alongside the fastest step-settle time available on the market. This means that long-distance z-stacking at high resolution has never been faster. High speed scanning can lead to oscillation, which in turn can lead to poor quality images and z-stacks, or even cause damage to the nanopositioning system. Queensgate products are designed to have high resonant frequency; combined with Queensgate’s proprietary digital control technology, this means that these systems can operate at best-in-class speeds without the risk of oscillation. Queengate’s expertise means that discarding images at the beginning of each stack due to system instability, or compromising on zstack acquisition speed, is no longer necessary.
