Subnanometer positioning for microscopy

The new PI nano series nanopositioning stages can be used for scanning microscopy, single molecule microscopy, 3D imaging, and autofocusing. They have a 20 mm (0.8 in.) profile, a large aperture and deliver subnanometer resolution in 2 and 3 axes. The included piezo controller has a 24-bit USB port, Ethernet, RS-232, and an analog interface, and it supports all major image acquisition software. The piezo stage can be used with the optional M-545 manual XY microscope stage, which is available in different versions for Olympus, Nikon, Zeiss and Leica microscopes.

For highly stable, closed loop operation, piezoresistive sensors are applied directly to the moving structure and precisely measure the displacement of the stage platform. The very high sensitivity of these sensors provides optimum position stability and responsiveness as well as sub-nanometer resolution. The proprietary servo controller significantly improves the motion linearity compared to conventional piezoresistive sensor controllers.
