Measuring displacements on the picometer scale

Controllers & Accessories

The optional PICOSCALE Breakout Box provides a simple and convenient access to the many different interfaces of the PICOSCALE controller.

Sensor Heads and Options

The PICOSCALE sensor heads are mandatory equipment to perform high resolution displacement measurements.

Measuring Displacements


For high precision displacement measurements, SmarAct offers the PICOSCALE Interferometer, a powerful sensor with picometer resolution. Based on an extremely compact Michelson interferometer, non-invasive displacement measurements with low restrictions on the target reflectivity can be realized very efficiently.

Sensor heads are available for general purpose or optimized for specific tasks like angular or differential measurements. Furthermore, we provide sensor heads for use in vacuum, cryogenic or other harsh environments. Due to their compactness, they fit into almost every setup. Powerful firmware modules and versatile accessories complement the PICOSCALE portfolio to emphasize its use as a laboratory device for synchronization with other devices, signal generation, real-time calculation and many more applications.
