The SP-DI series of laser measuring interferometers is a system for differential position and angle measurements with the highest accuracy by minimizing the dead path (the difference between the position of the reference and the measured object). The differential interferometer guarantees high long-term measurement stability.
The instrument is suitable, for example, for measuring positioning systems, for long-term measurement of mechanical properties of materials and dilatometry. It can also be adapted to be compatible with vacuum measurements.
