Full-field optical vibration measurement 

With the PSV-500 Scanning Vibrometer, you reliably and precisely measure vibrations in research and product development. 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 (NDT).

Highlights

  • Non-contact and full-field with FEM-like spatial resolution
  • Measure even on tiny structures due to smallest laser spot
  • Measure through water and other transparent media
  • Available as a compact notebook version or a classic rack system
  • Open interface for your applications
  • Expandable to 3D measurement system
  • Versatile accessories and software options

Scanning Vibrometers adopt to your measurement needs

Whatever question regarding vibration measurement drives you, there is a PSV Polytec Scanning Vibrometer to provide the answer – for frequencies from DC to 25 MHz, capturing vibrational velocities of 0.01 µm/s up to 30 m/s, studying samples from micro to macro. The precise helium-neon laser with its small laser measuring spot is suitable for measurements on extremely fine structures and even measures in and through water and other transparent media. For challenging measurements on technical surfaces, on dark, biological, moving or rotating test structures, the new PSV QTec Scanning Vibrometer is the ideal choice. 

Choose between solid rack type or flexible and portable notebook version. Whenever your requirements grow, benefit from upgrades and options or expand it to a full 3D scanning vibration measurement system.

Highlights

  • Non-contact laser vibration measurement
  • Full-field measurement with high spatial resolution
  • Available as a compact notebook version or a classic rack system
  • Open data and control interfaces for simple adaptation to your application
  • Can be upgraded and extended to create a 3D system
  • Versatile accessories and software options
