PicoScale Product Overview

The PicoScale is a powerful tool for displacement measurements. It is an interferometric displacement sensor based on an extremely compact Michelson interferometer with picometer resolution. Real-time position measurements allow to track target velocities of up to 1 m/s. The target reflectivities can be chosen almost arbitrarily and long working ranges are possible. Numerous digital and analog input and output interfaces allow to easily integrate the PicoScale in complex experimental setups.
