QTec® - Reinventing vibrometry
QTec® reinvents laser vibrometry by eliminating the root cause of noise delivering superior optical sensitivity, enabling high-fidelity measurements on all surfaces. In order to achieve this, QTec vibrometers use an innovative multi-path interferometer utilizing the highest quality signal of each path to reach the best results. This patented technology is combined with the well-proven infrared Xtra sensor design for faster, easier measurements and a consistent result.

Any questions about the QTec® multipath interferometry?
QTec® - Fast, easy, and reliable results
Ultra-fast electronics in the sensor head weight the detected signals in real-time and only the best part of the signal is transferred to a common output, making QTec® sensor heads compatible to current single channel vibrometer decoders.
The capability of QTec® to measure independently of the surface properties makes it a safe choice for all applications providing fast, easy, and reliable results.
