LC.400 Series
Piezo Controller OEM
nPoint has many options for OEM nanopositioning electronics. Based on the LC.400 series DSP digital control system closed-loop operation can be provided for three or more channels. Custom systems can be developed for easy integration.
nPoint controllers combine ultra low-noise driver electronics and motion sensing modules with DSP-based servo control. User-generated positioning commands are supplied via the analog BNC inputs, the USB interface, or via custom interface. nPoint’s linearization technique achieves positioning linearity better than 99.97% over the entire range of travel.
The LC.400 series controllers are compatible with capacitive and strain gage sensing technology to provide the most flexible nanopositioning controller on 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 are available to provide the necessary current for high-speed applications/ high-load configurations.
