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.
Highlights
