Xtra sensitivity in small spaces
The VibroFlex Xtra Fiber is a fiber-optic vibrometer sensor head designed for short measurement distances and hard-to-reach areas. Slim, flexible fiber cables access even the most confined spaces and narrow openings. The SWIR laser delivers high optical sensitivity for demanding surfaces in R&D and quality assurance, while the permanently attached fiber cable and compact mini fiber heads ensure stable, reliable measurements
VibroFlex – the superior flexibility of laser vibration measurement.
Highlights
- High-fidelity data from all surfaces – even on dark, biological or moving objects
- Micron-sized measurement spot for tiny structure
- High dynamic range up to 30 m/
- 10 mm diameter fiber-optic head reaches hard-to-access areas
- Wide range of optical accessories available
