- 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
- Xtra upgrade option for outstanding optical sensitivity
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.
Choose between solid rack type or flexible and portable notebook version. Whenever your requirements grow, benefit from upgrades and options. Add the optional Xtra technology to get high fidelity data even at large stand-off distances or on uncooperative surfaces or expand it to a full 3D vibration measurement system.
