Laser vibrometer products
Polytec’s laser vibrometers have become the globally recognized standard for non-contact vibration measurements. The extensive range of products offers you solutions to virtually any vibration-related issue in research, development, production and long-term monitoring.
Whether they are used for single-point or differential measurements, to determine rotational or in-plane vibrations, to visualize vibrations on MEMS and microscopic systems or for measuring and animating modal and operational deflection shapes: Polytec’s laser vibrometers provide a quick, non-contact and non-intrusive solution to your problem.
Single-point vibrometers
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 are laser vibration sensors that 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 vibrometers
Full-field vibrometer are vibration measurement systems that allow engineers to conduct areal deflection shape measurements as fundament for validating simulation models and identifying 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 and MEMS, Polytec presents this highly innovative product line of microscope-based measurement systems. MSA Micr System Analyzers from Polytec validate dynamics and topography of microsystems reliably with utmost precision.

PolyLab educational program
Do you want to prepare your students for the cutting-edge technology they will encounter in the industry? While many engineering disciplines involve the study of vibro-acoustics, the cost constraints mean that numerous school labs today are equipped only with basic accelerometers and microphones. Our PolyLab & PolyLab+ educational programs aim to bridge this gap, offering students the opportunity to familiarize themselves with state-of-the-art technology widely used in various industries.
PolyLab & PolyLab+ programs employ technology that goes beyond the limitations of traditional transducers. Vibrometers are indispensable for measuring on lightweight, very small structures, high-temperature surfaces, and underwater tests. Additionally, they can measure sub-picometer amplitudes and frequencies as high as 8 GHz.
Contact us to assess whether your institution qualifies for PolyLab or PolyLab+, and you may be eligible to receive free vibrometer loaners for educational purposes, ranging from 6 weeks up to 2 years.
