A new class – for new ideas
VibroScan QTec measures vibrations in a new way – non-contact and with unprecedented precision. With its groundbreaking multi-path interferometry and diversity combining, QTec® sets new standards in terms of optical sensitivity and interference immunity.
For the first time, QTec technology has been successfully transferred from the infrared SWIR laser to the visible helium-neon laser. With its small laser measuring spot, the precise helium-neon laser is suitable for measurements on the finest structures and even measures in and through water. These properties are a decisive advantage when determining operating vibration modes and eigenmodes in microsystems, electronics and medical devices, for example when analyzing sensor systems, hydrophones or ultrasonic components, over the entire frequency range up to 32 MHz.
The VibroScan QTec scanning vibrometer guarantees maximum portability. The VibroLink Ethernet data interface reliably transmits vibration measurement data to your notebook and serves as an automation interface.

Faster results with QTec® multi-path interferometry
The patented QTec® multi-path interferometer technology now also significantly boosts the signal quality for the visible helium-neon laser and guarantees maximum optical sensitivity. QTec® enables highly accurate results with the shortest measurement times regardless of the surface - even on dark, biological, rotating or moving objects. This safe laser technology is perfect for challenging applications, especially for smaller measurement objects. QTec® makes vibration measurements faster, easier and more reliable than ever – for the most robust, unambiguous results.
