nPoint controllers combine ultra low-noise driver electronics and motion sensing modules with DSP-based servo control. Up to six axes can be controlled simultaneously with the C.400 controller.

User-generated positioning commands are supplied via the analog BNC inputs, the USB interface or the optional high-speed serial interface. nPoint's linearization technique achieves positioning linearity better than 99.97% over the entire range of travel.

The C.400 is compatible with capacitive and strain gage sensing technology to provide the most flexible nanopositioning controller in the market. Moreover, stage calibration data and other parameters, such as control configurations, are stored in the ID-chip and are read automatically. High power amplifiers provide the necessary current for high-speed applications/ high-load configurations.
