Vibration analysis for RnD
Resolve from DC to 32 MHz bandwidth, sub-picometer displacements and up to 30 m/s fast movements.
Measure vibrations reliably and with laser precision on all surfaces – no matter if dark, oily, shiny or (red) hot.
Patented QTec® powerful on all surfaces
Always stable signal, 20 dB better SNR for faster and clearer results without post-processing: QTec® laser vibrometers use multi-path interferometry and reception diversity for recombining the best readings from different perspectives for faster and more consistent results while avoiding the need for averaging. This safe laser technology is perfect for challenging applications such as NDT, biomedical, long distance displacement measurements, quasi-static displacement measurement and shaker feedback control. The patented and highly innovative technology QTec® makes vibration measurements faster, easier and more reliable than ever - for the most robust, unambiguous results.
Best SNR with patented QTec® multi-path interferometry
The patented QTec® laser interferometer technology grants outstanding measurement data quality and best SNR (signal-to-noise ratio). Using the multi-detector concept of QTec® avoids speckle-dropouts and secures an all-time stable signal, for vibration analysis on fast moving or rotating sample objects.
