Nova-Xtra
Digital Free Beam SWIR Laser Vibrometer: Detect distant vibrations up to 300 m with our precision-enhancing Extra-Large-Lens system!
The Optomet Nova-Xtra is an extension of the Nova series and enables vibration measurements on distant objects with an extra-long range up to 300 m.
Higher laser power
Enhanced by the powerful yet discreet SWIR laser, the Nova-Xtra guarantees exceptional signal strength, ensuring optimal performance even in challenging conditions. This remarkable feature makes it the ultimate tool for professionals in civil engineering and the aerospace industry, who demand accuracy and reliability in their measurements.
Photodetectors in this wavelength range have an efficiency of more than 98%. In conjunction with the higher laser power, the signal level is 20 dB higher than that of conventional laser Doppler vibrometers.
Stability
With just a single longitudinal laser mode, the sensitivity is independent of changes in the measuring distance. The immediate operational readiness of the device after switching on and stability against fluctuations in the ambient temperature are further advantageous properties.
IR camera
For added convenience and versatility, the Nova-Xtra offers an optional IR camera. This additional feature allows you to visualize and precisely locate the laser spot on the object of interest, further enhancing your workflow and facilitating precise measurements.
Highlights
• Infrared laser (SWIR) for optimum signal quality
• Structural health monitoring by means of non-contact laser vibration measurement

Available Decoders
A wide variety of high-performance real-time decoders are available for the evaluation of the interferometric measuring signals. The Optomet UltraDSP technology enables the measurement of frequencies up to 25 MHz and vibrational velocities up to 25 m/s with the Fiber-Series, displacements can be resolved to less than 100 fm. All vibrometers incorporate a velocity decoder, and displacement and acceleration decoders are optionally available. Numerous measuring ranges per decoder ensure that measurements can always be performed with the optimum sensitivity.
Decoders can be easily retrofitted or upgraded. Start with a basic system and adapt the capabilities of the measuring instrument as required. This requires no return of the instrument to the factory and no waiting times for your production or research project. The table below provides an overview of the configuration options. We will also be happy to assist you in the selection of the best decoder for your measuring task.
