Laser Vibrometers

Polytec’s laser vibrometers have become the globally recognized standard for non-contact vibration measurements. But that’s hardly surprising, since the extensive range of products offers you solutions to virtually any vibration-related issue in research, development, production and long-term monitoring. Whether they’re used for single-point or differential measurements, to determine rotational or in-plane vibrations, to visualize vibrations on MEMS and microscopic systems or for representing entire structural vibrations in a complete, areal way: Polytec’s laser vibrometers provide a quick, non-contact and non-intrusive solution to your problem.

Full-field vibrometers

Full-field vibrometers keep the focus firmly on complex vibration behaviour over the entire surface and work contactlessly according to the laser Doppler principle. Polytec offers you turnkey solutions for everything from characterizing stationary vibration processes with scanning vibrometers to multipoint vibrometers (that measure in parallel) for non-stationary and transient processes. They shorten development times by giving you a comprehensive and precise insight into the dynamic behaviour of vibrating structures. They visualize eigenmodes and operational deflection shapes in a meaningful way and provide you with data quality that takes simulation model validation to a whole new level. Full-field vibrometers are complete solutions that are made up of sensor technology, data acquisition and analysis software. You can gradually retrofit and expand all the systems and also fully automate scanning vibrometers as your requirements grow.

PSV-500 Scanning Vibrometer

The Scanning Vibrometer provides you with a flexible vibration measurement platform that can be expanded at any time and that you can use to quickly and intuitively complete the most challenging vibration measuring tasks. This testing solution makes recording operational deflection shapes and Eigen modes child’s play.

PSV-500-3D Scanning Vibrometer

3D scanning vibrometers complete your vibration measurement tasks in product development in a reliable and precise way. The deflection shapes and eigenmodes detected help you with everything from NVH, acoustic and structurally dynamic issues to ultrasonic analyses, FEM validation and non-destructive testing.

MPV-800 Multipoint Vibrometer

48 eyes see more than one. The multipoint vibrometer opens up completely new vibration analysis possibilities for you – even for transient processes and on surfaces where tactile measurement methods reach their limits. The laser-based MPV-800 describes deflection shapes as a function of frequency and – for the first time ever – time too.


By combining a 3D scanning vibrometer and an industrial robot, RoboVib® offers you an automated measuring station for measuring everything from complex components to complete vehicle bodies. Both the amount of time required and the sources of error – especially in experimental modal analysis – are reduced significantly. So you can thoroughly test a vehicle body, for example, in just one to two days, whereas you would previously have needed weeks to even prepare for the test itself.
