The ECR4040 enables precise 360° endless rotation of samples in both directions. With an integrated 1/2" aperture it is suitable for optical experiments.
The positioner is designed for ambient conditions (/RT).
Our aluminum models combine a powerful piezoelectric motor with a lightweight body for easy integration in setups in atmospheric conditions.
