OFV-5000 Xtra Laser Vibrometer The OFV-5000 Xtra Vibrometer Controller in combination with the new MLV-I-0 Sensor Head is designed to flexibly measure vibrational velocity, displacement and acceleration. The Xtra optical sensitivity gathers high-fidelity data from all surfaces even on dark, biological, rotating or moving sample objects. An alternative exchangeable fiber lens as an addon to the MLV-I-0 head enables a dual purpose use for small objects and facilitates overhead measurements. The compactness of this robust sensor with different lens options leads to a versatile use and an easy integration into test setups. This non-contact approach solves challenging applications like NDT, biomedical, long distance displacement measurements, quasi-static displacement measurement and shaker control. Highlights Non-contact vibration sensor with Xtra sensitivity High-fidelity data from all surfaces even on dark, biological or moving objects From µm-sized to large, distant objects High dynamic with wide bandwidth up to 4 MHz Remote operation keeps laser precisely focused OFV-5000 Xtra Laser Vibrometer Xtra sensitivity and versatility Datasheet
