Laser Doppler vibrometers

Polytec vibration sensors are laser Doppler vibrometers that have become the globally established gold standard for non-contact vibration analysis. The complete product portfolio offers solutions to any vibration measurement task in research, development, production testing and long-term monitoring. Whether single-point or differential measurement, determining rotational vibrations or in-plane motions, visualizing the dynamic behavior of microsystems or full-field structural vibrations: Polytec laser sensors provide a quick, non-contact and non-intrusive measurement solution.

Single-point vibrometers

Measuring the transfer functions, amplitudes and resonance frequencies in a non-intrusive way with the simple “point and shoot” method is the single-point vibrometer’s specialty. You measure an object’s vibrations in the direction of the laser beam. From robust industrial vibrometers, to particularly compact designs, or systems with a modular approach – Polytec will always provide you with the ideal tools to suit your individual vibration measurement task.

Full-field vibrometers

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.

Microscope-based vibrometers

Inspired by the rapid further development of microelectromechanical systems (MEMS), Polytec is presenting an innovative product line of microscope systems for validating microsystems’ dynamics and topography.

Special-application vibrometers

If you’ve got special requirements, then you need special tools. No matter whether you’re carrying out measurement for ultrasonic applications in the very high frequency range, or need rotational vibrometers for rotating structures, or in-plane vibrometers for measuring vibrations perpendicular to the measurement beam – you’ll find the perfect solution at Polytec.

Software

Data acquisition, visualization and evaluation form the very essence of Polytec’s high-tech vibration measurement tools. And for this very purpose, Polytec is offering you high-performance software packages for device control, data acquisition and data processing that enable users to represent their measuring results in an intuitive and animated way and to exchange data with external software for the purpose of experimental modal analysis or FEM calculation, for example.

Accessories

Every application has its own measurement challenge. Here, the application-oriented setup and accessories make the difference, making metrology become a complete solution. For Polytec designers and engineers, comfort and flexibility are values with high priority, to make your Polytec vibromters work in any situation you need.

Measurement services

The range of measurement services offered by Polytec makes high-precision vibration analysies available to anyone by using our engineering services or system rentals. That way, you can use ultra-modern measuring technology and see, if you want to invest in your own equipment. We also offer our customers dedicated training sessions and application support services.

Technical service

Polytec instruments provide maximum precision. Our calibration service supplies you with valid proof time and time again. Our preventative maintenance service helps you to avoid failures and repairs, while our maintenance packages even help you to cut costs, too. But if you think something isn’t running the way it should, you’ll quickly find the help you need – no matter where in the world you’re based.
