Position noise

The amplitude of the stage shaking when it is on a static command. It is usually measured and specified with RMS (1 σ) value. It is commonly used to define the resolution of the nanopositioners and is a combination of sensor noise, driver electronics noise and command noise, etc.

Linearity error

The error between the actual position and the first-order best fit line (straight line). nPoint’s nanopositioning products are calibrated with laser interferometry and the non linearity errors are compensated with a fourth order polynomial.
