Psv 500 scanning vibrometers study measurement samples from micro to macro size. Psv 500 allow vibration measurement in a frequency range from dc to 25 mhz capturing vibrational velocities of 0 01 µm s up to 30 m s. Polytec manufactures a wide range of laser vibrometers that are the acknowledged gold standard for non contact vibration measurement.
