Superior flexibility in optical vibration measurement
Laser Doppler vibrometers from Polytec combine precise optical vibration measurement with easy and rapid operation. Measuring without contact, they sense the true vibrations of microscopic to macro-sized structures and lightweight components with the highest accuracy.
With VibroFlex, Polytec offers superior flexibility in optical vibration measurement with a modular sensor solution that adapts to your needs, from microscopic structures to large machinery at safe stand-off distances. Use it for research and product development to accelerate time-to-market, or for cost-efficient in-line inspections
times
The VibroFlex Connect+ front-end provides phase-synchronous reference acquisition, encoder based order analysis, an integrated signal generator, and PTP-synchronized multivibrometer setups with WiFi control via VibSoft.
Resolve vibrations from DC up to 32 MHz, quantify sub-picometer displacements, and capture velocities up to 30 m/s. Fiberoptics enable access to confined spaces, differential optics allow analysis of relative motions, and the integrated camera ensures precise laser positioning. Measure reliably on virtually all surfaces and at large distances.
