Laser Doppler vibrometers

The laser Doppler vibrometer VibroOne is the one-box solution for non-contact vibration measurement. It is specifically designed for tightly packed setups, whether in research laboratories, challenging production environments or for non-contact analysis of tiny details on microstructures or biomedical probes. The optional inline HD+ camera helps positioning the laser precisely and provides proper test documentation.

VibroGo® is the truly portable, battery powered digital laser vibrometer for field studies and quick and easy condition monitoring of machines and facilities on the go. Non-contact measurement of vibrational displacement, velocity and acceleration over a wide frequency range from DC to 100 kHz and from safe distances up to 30 m.

With the modular laser vibrometer VibroFlex, Polytec introduces the new flexibility in optical vibration measurement with a modular sensor solution that adapts to the users needs: Add microscope objectives for observing tiny structures or measure noise, vibration, harshness (NVH) on large, complex samples like machinery, motors etc. Discover acoustics and vibration phenomena in research and product development for a faster time-to-market or reliably and cost-efficiently inspect production parts in-line.

The Industrial Vibration Sensor is key to fast and non-contact vibro-acoustic quality inspection, structure-borne noise analysis and reliable pass-fail decisions. Its robust and compact design means you can optimally integrate it into process control systems and production environments with very short cycle times. The vibrometer is wear-free and saves you from using expensive servo-mechanisms or noise protection cabins.

Modular vibrometer systems offer both outstanding signal quality and maximum flexibility. They are made up of a sensor head and a controller that you can combine as required. You can therefore flexibly adapt your vibration measurement system to suit your individual measuring tasks and expand it as and when required.

The flexible vibration-measuring device with an integrated camera and a compact design is ideal for quality assurance and research. Additional microscope lenses expand the range of possible tasks that you can complete to include very small samples.

The PSV Scanning Vibrometer measures vibrations on an entire surface in a non-contact and laser precise way. This flexible measurement platform allows researchers and developers to master the most challenging vibration measurement tasks with ease. Upgrade or expand it to a full 3D system, once your application-specific demands grow. Detect and visualize operational deflection shapes and Eigen modes with this cutting-edge laser Doppler vibrometer.

PSV-3D Scanning Vibrometers measure 3D dynamics in research and product development in a reliable and precise way. The deflection shapes and Eigen modes detected help you with everything from NVH, acoustic and structurally dynamic issues to ultrasonic analyses, FEM validation and non-destructive testing.

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.

The all-in-one optical measurement solution for static and dynamic 3D characterization of MEMS and microstructures. The MSA-600 advances development and QC processes - and integrated into commercially available probe stations it even allows testing on wafer-level.

This brand new, patented measurement technology allows for comprehensive and representative analysis of Si encapsulated MEMS, measuring dynamics right through silicon caps. Our PolyXperts are looking forward to receiving your capped MEMS samples for modal testing, feasibility studies and consulting throughout all phases from development over prototyping to manufacturing of your encapsulated microstructures.

The 3D Micro System Analyzer records vibration components in all three spatial directions at once. The optical measurement system enables high-resolution 3D vibration analysis with amplitude resolutions in the sub-picometer range, for both in-plane and out-of-plane vibration components.

You use the entry-level device for microscope vibrometry to record vibrations on small components and microsystems with a high degree of precision over the entire surface. The device works contactlessly and therefore measures the dynamics of even small samples in a completely undistorted way.

The HSV-100 High Speed Vibrometer allows you to simultaneously measure displacements and vibrational velocities up to 40 m/s. To measure the valve train dynamics, the system can be expanded to include as many channels as you like and allows you to compensate for the test bench’s vibrations.

You can use the IPV-100 In-Plane Vibrometer to perform non-contact and non-invasive vibration and movement measurements perpendicular to the measurement axis (e.g. stroke movements of pistons, valve shafts and tools) or highly dynamic strain measurements.

The RSV-150 Remote Sensing Vibrometer performs high-precision measurements from a safe distance. Use this long-range laser vibration sensor to quickly and remotely measure vibrations and displacements on structures and machines. Point, shoot and measure with sub-micrometer resolution even at a distance of several hundred meters. Also suitable for drop and shock tests up to 24 m/s and frequencies up to the MHz range.

The RLV-5500 Rotational Laser Vibrometer measures the angular velocity and angular displacement of rotational vibrations on any shape of rotating structure. It precisely analyzes the rotational dynamics of drivetrains, gas turbines, electrical generators, printers and copiers, and thus enables you to develop products efficiently and quickly perform troubleshooting operations.

The package of Strain Processor in combination with a PSV-3D Scanning Vibrometers allow a non-contact, optical measuring alternative for dynamic stress and strain distribution and Finite Element model updates.

Standard spare parts we provide from stock. To keep your system up to the latest revisions, we supply parts with the latest improvements and firmware revisions included. 

Single-point laser Doppler vibrometers measure transfer functions, amplitudes and resonance frequencies without contact in a non-intrusive way thanks to the simple “point and shoot” principle. Single-point vibrometers measure object vibrations in the direction of the laser beam (out-of-plane motions). From modular concepts to robust industrial vibrometers or compact designs – Polytec will always provide you with the ideal measuerement tool to solve your individual vibration measurement task.

Full-field vibrometer models allow users to perform areal deflection shape measurements that are used to validate simulation models and identify vibration hotspots. They keep the focus firmly on complex vibration behaviour over the entire surface. Polytec’s product range includes everything from scanning vibrometers for stationary processes to multipoint vibrometers (that measure in parallel) for non-stationary and transient processes.

Inspired by the rapid further development of micro-electromechanical systems (MEMS), Polytec presents this highly innovative line of microscope-based measurement instruments for the reliable and most accurate analysis and validation of microsystems' dynamics and topography.
