Nanopositioning stage controllers with 24-bit resolution, will allow better than 100 picometers of command resolution for long-travel, piezo nanopositioning systems (1 mm and up). The converters offer an improvement of more than two orders of magnitude over 16-bit converters.
The controllers come in bench-top, rack-mount, and OEM card versions from single-channel units to multiaxis controllers with 12 channels/rack. The controllers feature a high-speed USB interface; an RS‑232 interface for industrial controllers, extensive software libraries and GUIs; support for LabView, Matlab, and text-based programming languages; analog interface for NI cards and analog control signals; up to 12 channels for multiaxis positioning applications; choice of position feedback sensors: capacitive and piezoresistive/strain gauges; an integrated servocontroller with a notch filter; and user programmable data tables for random waveform generation.
